Phylloscopus trivirgatus becki Hartert

Phylloscopus trivirgatus becki Hartert, 1929: 13 (Guadalcanar) .

Now Phylloscopus poliocephalus becki Hartert, 1929 . See Mayr and Diamond, 2001: 391.

HOLOTYPE: AMNH 220107 , adult male, collected on Guadalcanal (5 Guadalcanar)

Island, Solomon Islands, on 20 July 1927, by Rollo H. Beck on the Whitney South Sea Expedition (no. 26817).

COMMENTS: The AMNH number of the holotype was cited in the original description. Hartert’s (1929) paper in which this name was published dealt with Solomon Islands birds collected by the Whitney South Sea Expedition , which were never part of the Rothschild Collection ; thus, this type bears only an AMNH type label. Only part of the collection was sent to England for his study. According to Hartert (1929: 13), the type series comprised three males and one female. Nine specimens were collected on Guadalcanal in July 1927, so it became necessary to determine which ones Hartert had in hand when he described this form. The Whitney label of the holotype has Hartert’s newly introduced name written in his characteristic hand and black ink and marked with a red line drawn across the end of the label ; two male specimens and the female? are labeled in the same ink and hand, and I have considered them the paratypes. Their measurements agree with those given by Hartert in the original description. The paratypes are: AMNH 220105 , male, 20 July 1927, wing 58 mm ; AMNH 220106 , male, 20 July 1927, wing 59 mm ; AMNH 220109 , female?, 19 July 1927, wing 56 mm. The wing of the holotype measures 59 mm. I do not consider the following to be paratypes: AMNH 218144 , 218145 , 220104 , and 220108, which are labeled by the same hand that filled in the AMNH type label, itself labeled at AMNH, and AMNH 225201 , cataloged later and identified in yet a third hand .

According to Beck’s unpublished Journal D (Archives, Dept. of Ornithology, AMNH), the France was anchored near Cape Hunter (ca. 09.49S, 159.51E) and the expedition personnel spent 20–28 July inland from there, reaching as high as 4000 ft.
