Ampelion
If Ampelion was published after September 1846, ie 12/31/1846 Heliochera would be the genus name.
Thanks Mark. This led me to review my notes on
Ampelion, and to realize that, having started with Neave, I had indeed completely overlooked the appearance of the name on p. 21. |

On p. 21
https://biodiversitylibrary.org/page/40008067, the name was merely combined with one available species-group name, (
Ampelis rufaxilla Tschudi, published in 1844), in a list of known Peruvian birds.
On p. 137
https://biodiversitylibrary.org/page/40008183, a Latin diagnosis (by Tschudi?) and a German description (by Cabanis) were added; and three more, non-Peruvian species were included (
Procnias cucullata,
Ampelis rubrocristata,
Procnias melanocephala), in addition to
A. rufaxilla.
It seems in any case critical for the current use of the generic name that p. 21 pre-dates p. 137, because it is
only then that the type can be the single species included on that page. Should the two pages be given the same date (e.g., 31 Dec 1846), as they are clearly the same work, and as the same name, attributed to the same author, is used on both for what cannot reasonably be claimed to be two distinct concepts (one Peruvian species in a Peru-only list; that same Peruvian species and three others outside of the restricted context of this list), they would have to be considered in combination; if so there would be four OINS instead of one, and the type would be
Procnias cucullata Swainson 1821, because Gray designated that species in 1849
https://biodiversitylibrary.org/page/43592014. This would make
Ampelion a synonym of
Carpornis Gray 1846. (This name was indeed used for what is now
Carpornis until the mid-20th C.)
Some discussion of the dates of publication in Zimmer 1926:
https://biodiversitylibrary.org/page/36282989
1845 seems to be the most widely accepted year nowadays. It appears to derive mainly from Wagner, in the second
Heft of
Arch. Naturgesch. of 1846
https://biodiversitylibrary.org/page/13705313 , having listed
Lieferung VI of Tschudi's work, incl. the conclusions of the mammalogy and the first part of the ornithology, among the productions of 1845.
In
Isis https://books.google.com/books?id=GNOMs_DXZP8C&pg=PA311, OTOH, the same
Lieferung VI, with pp. 1-32 of the bird text, was announced in
Heft III-IV of the 1846 volume as dating from 1846.
Even if 1845 was not accepted, perhaps some "not-later-than" date could be derived from this ? (E.g., not later than 30 April 1846, based on the announcement in the April issue of
Isis ? Not sure to which extent this journal is known to have been in schedule at this time.)
