vallatds) on the dorsum, about 2 inches in advance of the frenum ; 

 the muscles of the tongue and their action were minutely described ; 

 also those of the larynx and pharynx. 



The brain, which weighed only 3 oz., presented a. narrow, elon^ 

 gated, depressed form, tlie back part of the cerebral hemispheres 

 resting against, but not overlapping, the cerebellum. The hemi- 

 spheres showed a few symmetrical convolutions ; they were united 

 by a large corpus callosum : the olfactory lobes are very large and 

 hollow. Many plexuses and other peculiarities of the vascular system 

 were noticed. 



This memoir v^ll appear, illustrated with numerous figures, in the

This little species, of which there are two examples in the National 

 Collection, both apparently Bogota skins, differs from all its conge- 

 ners in the colouring of the lower surface of the body, which is of a 

 pale reddish buff, growing much whiter in the middle of the belly. 

 Above the plumage is lead-coloured, with a greenish tinge super- 

 induced towards the lower part of the back. The wings and tail are 

 brown, with slight greenish edgings ; the ear-coverts and Avhole side 

 of the face are black. In the second specimen, apparently not so 

 mature, there is a light- coloured spot on the front, just above the 

 nostrils. The bill of this species agrees with that of Chlorospingus 

 atropileusy (Lafr.), in size, but is rather straighter in form, as in

•f - This bird seems intermediate between Tachyphonus and Pi/ranga, 

 and might be placed in either of these groups. The white axillary 

 feathers point to the former genus, the yellow rump to the latter. 

 The bill, however, is more compressed than is usual in Pgranga, and 

 agrees nearly with thsxio£ Tachgj^honus coronatus,(Viei\l.)M The upper
