3. Pseudochirus cupreus, sp. n. 



Size decidedly larger than in Ps. albertisL General colour 

 uniform dark coppery, very similar to that of Ps. cdbertisi co- 

 ronatus. Dorsal streak , although distinct , not strongly marked , 

 not reaching forwards on to the crown, and soon ending poste- 

 riorly. Ears with the marginal part of their inner , as well as 

 the whole of their outer surfaces well clothed with woolly hairs, 

 among which there are a few longer black bristles, but these 

 are both fewer and shorter than in Ps. albertisi. Under surface 

 with irregular patches of white on the chest and in the inguinal 

 region, the belly dull butty grey. Limbs darkening terminally, 

 the hands and feet black. Tail at its base very thickly hairy and 

 coloured like the body, but terminally, on the part which is naked 

 below, it is very thinly haired above as well, becoming gra- 

 dually practically naked at the extreme tip. The hairs on this 

 terminal part are black. Naked part below tip very coarsely 

 shagreened. 



Skull much larger and heavier than in the species above re- 

 ferred to. Nasals less markedly narrowed in front and expanded 

 behind than in Ps. albertisi. Interorbital space broad in front , 

 rapidly narrowing to a well defined waist ; supraorbital ridges 

 almost obsolete in front of the waist, but behind, on the brain- 

 case, they coalesce into a high median sagittal crest, a coalescence 

 wliich has not taken place in the oldest skulls of Ps. albertisi 

 or corinnae liefore me. Bullae well swollen , botli below and 

 behind. 



Teeth, apart from their greater size, agreeing fairly with those 

 of Ps. albertisi, although the upper canine is rather larger than 

 the premolar behind it, and the lower incisors are rather larger 

 and less concave above. Molars very large and massive.

Head and body (c) 425 ; tail (c) 330. Skull, basal length (c) 

 70; greatest breadth 47; nasals 23.5 X 11.8; interorbital con- 

 striction 7.2; palate breadth outside 7n^ 22.3, inside tn^ 13.6.
