TROCHILUS COLUBRIS.

On dissection the heart was found to he remarkably 
large, nearly as big as the cranium, and the stomach, 
though distended with food, uncommonly small, not 
exceeding the globe of the eye, and scarcely more than 
one-sixth part as large as the heart; the fibres of the 
last were also exceedingly strong. The brain was in 
large quantity, and very thin ; the tongue, from the tip 
to an extent equal with the length of the bill, was 
perforated, forming two closely attached parallel and 
cylindrical tubes ; the other extremities of the tongue 
corresponded exactly to those of the woodpecker, passing 
up the hind head, and reaching to the base of the upper 
mandible. These observations were verified in five 
different subjects, all of whose stomachs contained frag- 
ments of insects, and some of them whole ones.
