Crypturus berlepschi Roths., Bull. B. O. C, VII, 1897, p. v (Cachabfi, Ecuador). 



Apparently not uncommon in the Tropical Zone of the Pacific Coast, 

 though it appears not to have been before recorded from Colombia.

 Tinamus soui Hekbm., Tab. Aff. Anim., 1783, p. 165 (Cayenne). 



Two males from Villavicencio agree with two from Surinam, and indi- 

 cate that true soui ranges across northern South America to the- eastern 

 base of the Eastern Andes, doubtless as far south as the northern border 

 of the Amazonian forest line, or approximately to the Rio Guaviare. Fur- 

 ther south, in Colombia, it is replaced by C. s. caquetoe. Four males from 

 Trinidad ' are slightly larger, with larger bills than the four specimens above 

 mentioned but agree with them in color. I have seen no Guiana females.

Inhabits the Tropical Zone and lower border of the Subtropical Zone in 

 the Cauca and Magdalena Valleys. The birds from this area are difficult 

 to determine satisfactorily. The female is very close to the female of soui, 

 while the male is quite as near the male of modestus. Since, however, neither 

 of these names could be applied to them, it may, for the present, at least, 

 be advisable to use the name I have given above.
