Larus gelastes (1 Viewer)

[Gonçalo Elias]

The name Larus gelastes has been proposed (and used!) for the Slender-billed Gull. As far as I understand it was proposed by Lichtenstein.

But at some stage it must have been considered invalid... I can't understand why. Any hints?

What date is it? Larus genei dates from Brème, 1839.

Not sure, but this publication mentions 1838 - please have a look at page 60

Here there is also the date 1838, but attributed to Thienemann

Lichtenstein does not appear to have published it.

This name was indeed first published by Thienemann in 1838 (https://www.biodiversitylibrary.org/page/43814161), who attributed it to "Licht.", and did not describe the bird. (He merely provided a range statement.)
The first description was published by Keyserling & Blasius 1840 (https://www.biodiversitylibrary.org/page/15245726 & https://www.biodiversitylibrary.org/page/43814161), who attributed the name to "Lichtenstein Berol. Mus.", i.e., Lichtenstein in the Berlin Museum. This is later than the publication of Larus genei.
