markings of the common tamandua, the coloration being 

 nearly uniform yellowish brown, but varying from light straw 

 color to much darker in different individuals. In the other 

 specimen the nape, shoulders, and middle of the body all 

 around are dusky with the tips of the hairs yellow, and a 

 narrow median line of yellow extending from the shoulders 

 to the hips. This specimen strongly suggests the color pat- 

 tern of the common tamandua. The skull is larger than in 

 T. tetradactyla, with the rostral portion slenderer and rela- 

 tively longer, and the nasals are not abruptly expanded at 

 the posterior border, as is usually the case in T. tetradac- 

 tyla. 



All the specimens of Tamandua sent by Mr, Klages are of 

 the T. longicaudata type.

The 5 Suapure specimens and one of the 6 La Union speci- 

 mens are in the normal pelage of the type; the 2 El Llagual 

 specimens and 5 of the La Union specimens are melanistic. 

 In one of these the ventral surface is white; in another the 

 hairs of the ventral surface are dusky at base and conspicu- 

 ously tipped with white ; in all the others the ventral surface 

 is dusky, tinged with chestnut in two. There are traces of 

 the orange-rufous lateral line in several of the melanistic 

 specimens. The normal specimens are all white-bellied.
