Phelps and William H. PheIjPS, Jr. The situation of Cerro El Teteo, in the extreme southwest-ern part of the State of Taehira, in the Orinoco watershed, is described in our ''Five New Venezuelan Birds and Nine Ex-tensions of Ranges to Colombia."^ The ranges of ten species or subspecies are here extended to Venezuela and that of one subspecies to Colombia. We thank Dr. John T. Zimmer, Chairman of the Department of Birda of the American Museum of Natural History, for access to that collec-tion. Specimens are in the Phelps Collection, Caracas, unless otherwise specified. Names of colors are capitalized when direct comparison has been made with Ridgway's "Color Standards and Color Nomenclature," 1912. Wiug measurements are of the chord.

These specimens constitute an extension of range to Venezuela from southeastern Colombia where the subspecies is known only from the type locality and from "Bogota" (de Schauensee, Birds of Colombia, p. 418, 1949). Cerro El Teteo is less than 50 miles, due east, from Pamplona, on the southern approaches to the Paramo de Tama. Nyctibius griseus panamensis Ridgway Nyctihius griseus panamensis Ridgway, Proc. Biol.

These specimens constitute an extension of range of the subspecies to Venezuela from northern Colombia. Measurements of the adults: 1 $ — wing, 281 mm.; tail, 195; 1 $ — wing, 276; tail, 198. The following measurements of specimens from north of the Andes along the Colombian frontier in Urena, northwestern Taehira, and the Perija Mountains, Zulia, correspond decidedly to those of the smaller race, N. g. griseus (Gmelin) of southern Venezuela: 3 $ — wing, 242-260 (252); tail, 164-184 (174); 2 ?— wing, 248-256 (252); tail, 170-176 (173).
