Show 140 MR. O. SALVIN ON THE BIRDS OF VERAGUA. [Jan. 24, 52. TACHYPHONUS DELATTRII, Lafr. Santa Fe and Santiago de Veragua. 53. ARREMON AURANTIIROSTRIS, Lafr. Santa Fe. 54. BUARREMON CRASSIROSTRIS. (Plate XIV.) Buarremon crassirostris,Cassin, Proc. Acad. Sc.Phil. 1865, p. 170. Buarremon mesoxanthus, Salvin, P. Z. S. 1866, p. 72. Santiago de Veragua and Cordillera de Tole. As in the case of Euphonia annee, Mr. Cassin's description of this bird has several months priority over mine. In comparing the species with B. castaneiceps, Scl. P. Z. S. 1859, p. 441, I have, I believe, indicated its true affinity. These two species constitute a very marked section of the genus Buarremon, which comprises several distinct groups, 55. BUARREMON BRUNNEINUCHUS (Lafr.). Santiago de Veragua ; Cordillera de Tole. Though strictly an inhabitant of mountainous regions, this species is remarkably constant in its characters, specimens from Mexico, Guatemala, Costa Rica, and Ecuador not differing in any appreciable degree. 56. SALTATOR MAGNOIDES, Lafr.; Scl. P. Z. S. 1856, p. 142. Saltator intermedius, Lawr. Ann. N. Y. Lye. viii. p. 175. Santa Fe; David (Bridges; LLicks). Two male specimens from Santa Fe have a slightly fulvous tinge on the under plumage, and more than is usually noticeable in Guatemalan specimens of this bird. This is, I have little doubt, the bird Mr. Lawrence has separated under the name of S. intermedius. In our article on the "Birds of Panama," Mr. Sclater and I united this bird with S. magnoides; but Mr. Lawrence, in his list of Mr. Hicks's Chiriqui collection (Ann. N. Y. Lye. viii. p. 175), maintains the opinion he formed as to their distinctness. The question at issue concerns the constancy of the characters Mr. Lawrence points out. They are as follows :-(1) In intermedius the feathers of the occiput are mingled with olive-green, (2) the white of the throat extends to the chin, (3) the fulvous of the throat is less bright but twice as extensive, (4) the black band of the chest one-third as wide as in the magnoides, (5) under plumage tinged with fulvous instead of clear cinereous, and (6) the crissum darker. I have before me eleven specimens from Guatemala, two from Costa Rica, three from Veragua, and three (two males and a female) from Panama, in all nine- » teen specimens. (1) All specimens have olive-green feathers on the occiput; but in Guatemalan specimens the remaining feathers are in general (not in all specimens) blacker. (2) In several of our Guatemalan specimens the white of the throat extends to the bill, in others it does not, nor does it in one of the Panama specimens. (3) As regards the brightness of the fulvous of the throat there is a consider- |
