Troch. t. 21 7; H. violifrons, Intr. p. 122), and conclude that Carthagena, and not Veragua, must be its proper habitat. 139. PETASOPHORA CYANOTIS (Bourc); Gould, Mon. Troch. t. 228, Intr. p. 125. P. cabanisi, Lawr. Ann. Lye. N . Y. ix. p. 126. Calovevora ; Chitra ; V. de Chiriqui. The differences pointed out by Cabanis and Lawrence between Costa-Rican and New-Granadan"specimens of this bird appear to me to be exceedingly slight; and, so far as a considerable series of specimens show, the points of distinction are not so constantly present as seems requisite for the recognition of specific difference between the two races. 140. PETASOPHORA DELPHIN^E (Less.); Gould, Mon. Troch. t. 229, Intr. p. 125. Calovevora. This species is sparingly distributed throughout Central America, as far north as Coban in Vera Paz. Heliomaster longirostris. Calovevora; Chitra; Laguna del Castillo; Cordillera del Chucu. Thaumantias chionurus. Calovevora ; V. de Chiriqui. Amazilia riefferi. Calovevora ; Cordillera del Chucu. Erythronota niveiventris. Calovevora; Chitra; Cordillera del Chucu ; V. de Chiriqui. The range of this species seems almost entirely restricted to Veragua. W e have a single specimen which was collected on the Panama Railway-line by the late Mr. J. M'Leannan. 141. EUPHERUSA EGREGIA, Scl. & Salv. P. Z. S. 1868, p. 389; Lawr. Ann. Lye. N . Y. ix. p. 146. Since the above species was described we have received numerous specimens, both from Costa Rica and Veragua. The adult bird is exceedingly like E. eximia of Guatemala, but seems to differ constantly in the greater amount of white on the rectrices. Mr. Lawrence has given (I. ci) a carefully drawn account of the specific differences between the two species. 142. EUPHERUSA NIGRIVENTRIS, Lawr. Proc. Ac. Phil. 1867, p. 232. Cordillera del Chucu. Arce procured specimens of both sexes of this remarkable species in the above locality. The female, which has not yet been characterized, may be described as follows : - Supra viridescens, pileo paulo obscuriore : subtus sordide alba, hy- |
