Basileuterus nigrivertex Salvin

Basileuterus nigrivertex Salvin, 1895: 3 (Cajabamba, Suecha, and Huamachuco) .

Now Myiothlypis nigrocristata (Lafresnaye, 1840) . See Hellmayr, 1935: 478; Ridgely and Tudor, 1989: 186–187; Curson, 2010b: 788; and Lovette et al., 2010: 766.

SYNTYPES: AMNH 505579 , female, collected at Cajabamba , 9000 ft, 07.37S, 78.03W ( Stephens and Traylor, 1983), Cajamarca, Peru, in January 1894 ; AMNH 505580 , female, collected at Cajabamba , 9000 ft, in January 1894 ; AMNH 505582 , female, collected at Huamachuco , 10,400 ft, 07.48S, 78.04W ( Stephens and Traylor, 1983), La Libertad, Peru, in February 1894 ; AMNH 505583 , sex?, collected at Suecha , Huamachuco, 9000 ft, Peru, in February 1894, all collected by O.T. Baron.

COMMENTS: Salvin (1895: 1–22) reported on the birds collected by Baron on his first trip to Peru, the collection being partly in the Salvin and Godman Collection (now in BMNH) and partly in the Rothschild Collection ; species that were represented in the Rothschild Collection were indicated with an asterisk next to the name. A number of new forms were described in this paper but no holotypes were designated; therefore all the specimens of a new form in both collections are syntypes. The above syntypes were not listed by Hartert in any of his Rothschild Collection type lists and they had not previously been recognized as types. However, all four are labeled ‘‘ Basileuterus nigrivertex Salvin’’ in what is apparently Salvin’s hand, and AMNH 505580 and 505583 are both marked ‘‘Co-type’’ in the same hand. Syntypes in BMNH are listed by Warren and Harrison (1971: 383) .

Another specimen collected by Baron on his second trip was collected in 1895 and is not a type. Baron (1897) published a description of his collecting localities.
