    ABSTRACT: The year that Gyps africanus was described is well known, but almost all recent
    authors cite an incorrect reference paper, published some years later. The evidence reveals that
    Salvadoriʹs description was published in at least three different versions, with differences in the
    wording. This seems most likely to have been caused by a failure in thorough planning of when
    and where to publish the papers read to the Reale Accademia delle Scienze di Torino, after the
    reports of such meetings ceased to be published in the Memorie della Reale Accademia delle Scienze
    and began to be published independently, in the Atti della Reale Accademia delle Scienze.
    Presently available evidence reveals the exact day on which the binomial Gyps africanus was
    introduced, and the original version of the reference text. In this the author used two spellings
    affricanus and africanus, a situation resolved by the application of Art. 24.2.4 of the Code
    (I.C.Z.N., 1999).

    KEYWORDS: Gyps africanus, Tommaso Salvadori, original description, original spelling, citation,

INTRODUCTION

     The name Gyps africanus was proposed and the taxon described by Tommaso Salvadori in
a paper read by Filippo De Filippi at the Reale Accademia delle Scienze di Torino (Royal
Academy of Sciences of Turin) during the session of 7 May 1865. The date is clearly
established, like that of every session of the Academy. However, an oral declaration is not
publication and the International Code of Zoological Nomenclature (I.C.Z.N., 1999) dates
publication from printing and distribution.
     Over the years a number of different titles (or their abbreviations) have been cited and
there has been some dispute over the source and the date of that publication. The purpose of
this article is to identify the full title of the journal concerned and the correct publication date.
     Following some initial doubt that this was a distinct species (see Anon., 1865b: 339; von
Heuglin, 1867a: 199), Salvadori’s new taxon was accepted and it has usually been attributed
to the genus Gyps as proposed by Salvadori, although it was attributed to Pseudogyps by Sclater
(1924: 48) and Friedmann (1930). This genus is sometimes split and Wolters (1975) placed the
species in the subgenus Pseudogyps.
     The year date 1865 has been in general use, see Sharpe (1874: 12), Swann (1919: 5),
Friedmann (1930: 42), Peters (1931: 262), Wolters (1975: 79), Stresemann & Amadon (1979: 305),
Brown (1982: 326), Dickinson (2003: 102), del Hoyo et al. (1994: 126), Dickinson & Remsen
(2013: 239), del Hoyo & Collar (2014: 526). Only Royal Society (1879: 821) and Mundy et al.
(1992: 122) differed citing 1869.

WHERE AND WHEN WAS THE FIRST DESCRIPTION OF GYPS AFRICANUS PUBLISHED?

    The survey tabulated above includes reports of the oral introduction of the name and
reports on the publication name and details.
    Since the work of Salvadori was read on 7 May 1865 in a session of the Academy of
Sciences of Turin, one would expect to find the publication in one of the two journals of the

Academy: Memorie della Reale Accademia delle Scienze di Torino (of which the first numbers date
back to the end of the 18th century) or Atti della Reale Accademia delle Scienze di Torino (the first
volume, 1865‐66, is dated 1866). In fact, the description of Gyps africanus never appeared in
these journals. Sobrero (1869: 2) explained that the reports of the sessions of the Academy prior
to 1864 (i.e., until the end of 1863) were always printed at the beginning of the volumes of the
journal Memorie, and that it was intended that the subsequent ones would appear in the
Acanemy’s new journal, the Atti. However, the first volume of the Atti published works read
to the Academy since November 1865; thus, the publications based on papers read between
31 January 1864 and 2 July 1865 appear neither in the Memorie nor in the Atti.
     The earlier reports mentioning this work by Salvadori either refer to the date of the
meeting of the Turin Academy of Sciences on 7 May 1865, at which Salvadoriʹs work was read,
or cite the Gazzetta Ufficiale n. 126 of 1865. Salvadori (1870: 721) was the first author to state
that the paper with the description of Gyps africanus had appeared in the Notizia storica dei
lavori fatti dalla reale Accademia delle Scienze di Torino (hereafter Notizia Storica), however, he did
not specify the date, although quoting the Gazzetta Ufficiale of 1865, and also referring to the
“Giorn. Off.ʺ. Almost all subsequent citations associate the first description with the Notizia
Storica, and (wrongly) date it to 1865, although, as shown above, they use different words and
abbreviations for the journal. Only Royal Society of London (1879: 821), Mundy et al. (1992:
122) and Aimassi et al. (2020: 82) have cited the Notizia Storica with Salvadoriʹs paper with the
date 1869.
     In fact, it appears that first publication was in the Gazzetta Ufficiale No. 126 of 27 May 1865
(Salvadori, 1865a; Figures 1a and 1b).
     Surprisingly, the same paper appeared in another journal, the Giornale delle Alpi, degli
Apennini e Vulcani (Salvadori, 1865b), but none of the authors listed above (Table 1) reported
the description of G. africanus from this journal, which was published only for a very short
period, between 1864 and 1866. Its name was changed to Rivista delle Alpi, degli Appennini e
Vulcani starting with issues 7‐10 in “Anno II”. Salvadoriʹs paper was finally republished as
part of an occasional work of the Turin Academy edited by the secretary Ascanio Sobrero, the
ʺNotizia Storicaʺ mentioned above (Salvadori, 1869). Two undated separates of this paper have
been found: one is present in the library of the Accademia di Agricoltura di Torino, and the
other is in the Museo Regionale di Scienze Naturali di Torino.

THE ORIGINAL SPELLING

   The texts of the different versions of Salvadoriʹs paper do not have exactly the same
wording, but it is not necessary to describe all the differences in detail. However, it is
important to focus on the spelling of the new taxon, which appears in two different ways:
    1. “affricanus” in the first (Salvadori, 1865a) and in the second work (Salvadori, 1865b), but
       towards the end of the paper, in both versions, G. africanus also appears, with a single
       “f” (Figure 2);
    2. “africanus” in the third work (Salvadori, 1869) (Figure 3) and in the undated reprint.
     Article 24.2.3 of the International Code of Zoological Nomenclature (I.C.Z.N., 1999)
introduces the requirement of selection of correct original spellings, which must take place “if
a name is spelled in more than one way in the original work” (in this case affricanus and
africanus). The same article of the Code establishes that “the first author to have cited them
together and to have selected one spelling as correct is the First Reviser”. Article 24.2.4
establishes that, if the original author of the name uses one of the two spellings as valid in a
subsequent work before any other action under Art. 24.2.3, he is considered to be the First
Reviser and the spelling used by him becomes the “correct original spelling”. No case has been
identified where Article 24.2.3 was applicable, but Salvadori (1869) only used the spelling
“africanus” and thus became the First Reviser.
     This case of double spelling is analogous to many of those listed by David et al. (2009),
Part I(b), Species‐group names. Fortunately, the First Reviserʹs non‐explicit choice corresponds
to the spelling “africanus”, the only one currently in use, so no further action is needed.

1   This edition of Salvadori’s paper can be found online in a volume kept in the Bodleian Library and digitized
    by Google books. Unfortunately, this book (which actually corresponds to the entire “Anno II”, 1865‐1866,
    parts 1‐11) was clumsily bound and, as a cover, it has the issue wrapper only relating to parts 7‐11, published
    in 1866 when the name of the journal had already been changed to “Rivista delle Alpi, degli Appennini e Vulcani”.
    Correct correspondence between volume and scan has been confirmed by Bodleian Library (Alan Brown, pers.
    comm., 17 January 2022).
