ut' both upper and lower anterior incisors, and by tlie marked 

 difference in the size of the u{)per canine and anterior pre- 

 molar. 



^. Pseudochirus albertisi coronatus, subsp. n. 



Similar in essential characters to the typical form, but the 

 fur of the body enormously lengthened (hairs of back 30 to 

 3o mm. long), the coloration deeper, richer and more coppery, 

 the brown of the hands, feet and tail darkened to shining black, 

 and the dorsal line extending on to the crown of the head, where 

 it trifurcates and forms a sort of cross. On the undersurface , 

 instead of a white mesial patch , sharply defined , th(^ lighter 

 colour is little defined , and strongly suffused with fulvous 

 brown. 



Cranially there is only available a young skull of coronatus 

 for comparison with old ones of lypicus, but the posterior part 

 of the nasals and the interorbital region just behind them are 

 so very much narrower than in typiciis that it seems unlikely 

 they would ever have attained the remarkable breadth characte- 

 ristic of that form. Tliis difference is so great that if it is not 

 reduced with age the two animals would have to be considered 

 as different species. The teeth seem to be essentially similar 

 in form , and also , allowing for their unworn and uncrushed 

 state, in size. 



Dimensions of the type, a young sjiecimen in skin : 



Head and body (c) 250 ; tail (c) 220 mm. Skull, basal length 

 48.5; greatest breadth 32.2; nasals 17 X 8; horizontal length 

 of posterior upper premolar 4.5; of molars ^ - ^ combined 13.5. 



Hab. Arfak Mountains, N. W. New Guinea, at 2000 metres 

 altitude. 



Type. Brit. Mus. 94. 2. 14. 4. Collected b\ Mr. Burke. 



The British Museum possesses a specimen of the typical Pn. ai- 

 bertisi from Moeri also in the Arfak mountains at about 1000 m. 

 altitude. At these two altitudes Mr. Biirke also collected specimens 

 respectively referable to Phalanyer orientalis lypicus (1000 m.i 

 and Ph. o. veslitus, M.Edw. (2000) wiioso differences in pelage 

 are verv similar to these found in the two Pseudoc/tiri.
