5i4 BIRDS OF BRITISH GUIANA. 



proportion to the size of the bird itself. Its width and depth at the 

 base are equal, which is about two-thirds the length of the exposed 

 culmen ; the tip of the upper mandible is slightly hooked, but there 

 is no trace of a tooth on its cutting edges. There is a tuft of 

 velvet-like feathers immediately behind the nostrils. The wing is 

 rounded, the second, third, and fourth primaries are longest iind 

 equal, the first is slightly shorter than the fourth but much longer 

 than the fifth. The tail is square at the tip and about two-thirds 

 the length of the wing. The tarsus exceeds the length of the 

 exposed culmen by about one-third. Coloration : male and 

 female slightly different.

Habits. Beebe (Tropical Wild Life in British Guiana, p. 137) 

 records this species from Bartica, which, so far as I have been able 

 to gather, is the first known occurrence of the species in the 

 colony. It may be mentioned, however, that Messrs. . Penard 

 (Vogels van Guyana, ii. p. 463) described a new form of this 

 species, founded on its larger wing-measurement, viz., It'S. This 

 does not appear to be of any great importance, however, when we 

 find that the wing-measurement of some of the Cayenne birds 

 reaches 9"1. If, on the other hand, Messrs. Penard's bird should
