mouse gray, becoming dark mouse gray on the hind neck; a slight 

 buffy tinge to the edges of some of the feathers of the crown. Upper- 

 parts and lower fore neck chestnut brown with traces of vermicula- 

 tions; upper breast chestnut brown, shading into vinaceous buff on 

 the lower abdomen; feathers of the flanks and abdomen with dusky 

 brown bars, the tips vinaceous buff; under tail coverts heavily barred 

 with dusky brown, the tips vinaceous buffy. Primaries hair brown, 

 the outer edges of the outer webs showing a brownish tinge ; secondaries 

 hair brown with outer webs and tips broadly margined with chestnut 

 brown. Wing, 143 ; culmen, 23 ; tarsus, 40 ; middle toe with nail, 36. 

 This tinamou was seen only at La Azulita where a male bird was 

 flushed from a nest on April 21st. The nest was simply a hollow 

 between the roots of a small tree in the deep woods, and contained 

 three fresh eggs, of a deep pink color. Unfortunately through a misr 

 hap these eggs were lost. 



Many times in the next week the whistling call of this bird was 

 heard, so it is probably fairly common, but very hard to secure because 

 of its secretive habits. The only other species of tinamou inhabiting 

 this district was Tinamus tao septentrionalis, which was also very diffi- 

 cult to secure, although its call was heard every day. 



Local name, Suida. 



Crypturornis soui subsp. ? 

 Rio CogoUo, I. 

 A tinamou of the som series in immature plumage with pale tips 

 to the upper wing and tail coverts was taken on the Rio CogoUo Feb. 

 23rd. Several others were seen on the same day, but at no other time. 

 These birds were found in a mass of brush and vines which they re- 

 fused to leave. They seemed more inclined to flush than the larger 

 species, but would pitch again into the brush after a few yards. It 

 was almost impossible to secure them without damaging the specimen 

 badly. 



Crypturornis noctivagus spencei Chubb. 



Rio Cogollo, 3. 



These specimens are provisionally referred to C n. spencei (Bull. 

 Brit. Om. Club, Vol. 38, p. 29, 191 7) although no material has been 

 available from the vicinity of Caracas, the type locality of that form. 

 In comparison with C. n. noctivagus of Brazil, C. n. dissimilis of 

 Guiana, and C. n. cinnamameus of Central America, they are much 

 paler in general coloration, the breast being buffy instead of tawny
