[QUOTE="l_raty, post: 3639650, member: 24811"] Out of the top of my head, at least this one is missing: [U]Taxon:[/U] [I]Larus argentatus lusitanius[/I] Joiris 1978 (Aves: Charadriiformes: Laridae) Joiris C. 1978. Le Goéland argenté portugais (Larus argentatus lusitanius), nouvelle forme de Goéland argenté à pattes jaunes. [I]Aves[/I] 15:17-18. [[URL="http://www.aves.be/fileadmin/Aves/Bulletins/Articles/15_1/15_1_17.pdf"]pdf[/URL]] [U]Types:[/U] Over 200 birds form the base of the description. In the absence of any explicit type designation, these are all syntypes. [U]History:[/U] Based on birds observed on rocky cliffs and islets near Peniche, ~75 km NNW of Lisbon, Portugal, alongside three birds that the author identified as '[I]L. a. argentatus[/I]'(*). Written description only, based on observation in the field; none of the syntypes collected, photographed, or illustrated in any other way; absolutely nothing preserved; no explanation or justification of these facts. [U]Current status[/U]: Most often synonymized with [I]michahellis[/I] Naumann. (The name is regularly used as a somewhat informal label to denote a geographical variant of the latter, that would be distinct in some aspects at least.) Usually regarded as available, however, even if reluctantly. *) Circumscription not made explicit. [I]L. a. argenteus[/I] Brehm (& Schilling [?]) was not yet universally recognized back then; it seems reasonably possible that the author intended his '[I]L. a. argentatus[/I]' as encompassing all European 'pink-legged herring gulls'. ([I]argentatus[/I] as currently defined is but a vagrant in Portugal. The author and journal are Belgian; in the text the taxon is called "our pink-legged [I]L. a. argentatus[/I]" without even citing [I]argenteus[/I]; yet the latter is by far the most frequent taxon in Belgium. The text also implies [I]argentatus[/I] is smaller and paler than [I]michahellis[/I]; this makes better sense if the taxon encompassed the current [I]argenteus[/I].) [/QUOTE]
