BIRDS IN THE MUSEUM OF VASSAR COLLEGE. 115 
Diglossa aterrima Lafr. The natives say that it changes 
its colors if taken to Pichincha, becoming like D. Lafresnayi. 
Rupicola sanguinolenta Gould. This splendid “Cock of 
the Rock " is found only, we believe, on the western Andean 
slope. The R. Peruviana is confined to the eastern slope, 
and the R. crocea to the mountains of Guiana. It fre- 
quents shady ravines and is very shy. It “plays "possum," 
falling apparently dead when shot at, but soon flies off. It 
makes a guttural noise not unlike the grunt of a hog. Like 
the Bird of Paradise, Peacock, Turkey, etc., the Cock of 
the Rock makes an extraordinary display of its finery just 
prior to the breeding season. 
Chrysomitris Mexicana Bp. Tyre of Fringilla Texensis 
ir. 
Ocyalus latirostris Sw., Clypicterus oseryi and Amblycer- 
sus solitarius. These splendid specimens of Icteride were 
obtained on the Upper Amazon, where they appear to be rare. 
Icterus G'race-annae Cass. This seems to be the only spec- 
imen found since its description. The type is in the Phila- 
delphia Academy. This fixes the locality (Machala near 
Guayaquil), which was not positively known. 
Cephalopterus ornatus Vieill. This Umbrella Bird came 
from the Upper Amazon. It was formerly thought to be 
confined to the islands in the Rio Negro. It is found only 
on the eastern side of the Andes; the C. penduliger being re- 
stricted to the western slope, and C. glabricollis to Contin 
America. The throat lappet of penduliger is nearly ten 
inches long; that of ornatus about four, and of glabricollis 
insignifieant. According to Fraser, the appendage seems 
generally held in a bunch like a rose under the throat, and 
to fall after death. ` 
Chlorenas vinacea and Ortolida guttata; from the Upper 
Amazon. Near Savonita on the west slope of the Andes is 
an Ortolida whose note sounds like £rabajá, trabajá (work! 
work !), and the response of the answering bird is manana, 
manana (to-morrow), a parody on Spanish character.
