a small white wing-spot/' and suggest that it might be 

 correctly referable to C. gaianensis. We may therefore 

 regard the so-called species C. major as having probably 

 been founded upon a few mongrel examples obtained on the 

 border-line between the areas of distribution of C. luieola 

 and C. guianensis, and for this reason it would seem 

 advisable to sink the name altogetlier or regard it as a 

 synonym of C. luteola or C. guianensis. 



CnniEBA LUTEOLA MONTANA, subsp. UOV. 



Ttjpe. Ad. S,20.n.07, Merida (1600 metres), Brieeuocoll. 

 in Mus. Rotlischild., Tring. 



Measurements. Bill 14 mm. (exposed culmen) ; wing 

 63 mm. ; tarsus 16 mm. 



I hav^e examined a series of nineteen specimens from tiie 

 mountainous district of Merida (Western Venezuela) con- 

 tained in the collection of Mr. Walter llothschild at Tring. 

 These birds are darker and richer than typical specimens 

 of C. luteola (Cumanii) and have the coloration of the rump 

 more olive yellowish. They have also obviously larger bills 

 (average 14 mm., as compared with 11 mm. in typical 

 specimens) , and the wings are noticeably larger. The throat- 

 patch is dark ashy grey as compared with light ashy in 

 typical C. luteola. It is highly probable, therefore, that the 

 birds which inhabit the main mountain-chains of Venezuela 

 are generally larger and more richly coloured than those of 

 the coast district, as I have already pointed out in the case 

 of Ti'inidad birds ("^ Ibis,' 1907, p. 566). I have therefore 

 deemed it advisable to distinguish this mountain race from 

 the Merida and possibly other mountain districts by a 

 definite name.
