336 Mr. P. L. Sclater on the Range 



Humboldt also met with a nocturnal bird in the caverns 

 of Icononzo or Pandi, near Bogota, where it is called Caca ; 

 and Roulin, who visited its breeding-places in the same 

 caverns in 1827, showed that this bird was the Steatornis 

 (Compt. Rend. iii. p. 94). Roulin also met with Steatornis 

 in the "Quebradanegra" or " Quebradahonda" of Guaduas, 

 in an adjoining canton of Bogota. 



The occurrence of Steatornis in Trinidad was first made 

 known by Latham, who described it anew as the " Trinidad 

 Goatsucker" (Gen. Hist. B. vii. p. 365), from observations 

 and a specimen furnished to him by Mr. J. V. Thompson. 

 In 1838 M. Hautessier visited the caverns which it inhabits 

 on the sea near the Boca del Drago, at the north-west, 

 corner of that island*, and obtained specimens of the 

 bird and its nest and eggs (see Compt. Rend, vii. p. 474 

 1838; and Rev. Zool. 1838, p. 164). Another Guacharo 

 cave in Trinidad was visited by Mr. E. C. Taylor in 1863 

 (Ibis, 1864, p. 88) , and Sir Arthur Gordon (Governor of the 

 island) actually brought a specimen of the bird alive to 

 the Zoological Society's Gardens in 1869 (see P. Z. S. 1869, 

 p. 467). 



Besides the cavern of Caripe in Venezuela, the Guacharo 

 is also found at Copas, north-west of Merida, in the ravine 

 crossed by the Puente Natural of Copas, as testified by Goer- 

 ing (P. Z. S. 1870, p. 779). 



In British Guiana the Guacharo occurs in a cave near the 

 Indian village of Ackar, on the Upper Mazaruni River 

 (Brown, 'Canoe and Camp Life in Brit. Guiana/ p. 386), 

 and in the vertical rocks of Roraima (Salvin, c Ibis/ 1885, 

 p. 439). 



In the U.S. of Colombia, besides the two localities indi- 

 cated by Roulin, the Guacharo is also found in the chasm 

 called " Hoyo del Aire," fourteen miles N.N.E. of Velez 

 (Holton's ' New Grenada/ New York, 1857, p. 263), and 

 near Sta. Elena, in the State of Antioquia (Scl. et Salv. 

 P. Z. S. 1879, p. 532). 



* See also ' Report U.S. Fish Commission, 1884,' p. 90, for an account 

 of a visit to these caves (cf. Ibis, 1887, p. 477).
