Although superficially very like tlie other two species, C. crassn maj' be readily 

 recogniseil by its reduced interfemoral menibraiie and calcars, and by the different 

 proportions of its incisors and anterior premolars.

5. Vesperugo papuanus l'<t. i^i Dor. 

 Several specimens. 



<>. Chiniromys pulcher sj). nov. 



Kather larger tlian Vh. forbeni ; proiiortions as in that species. Fur longer and 

 softer, the hairs in the middle of the hack about 15 to 16 mm. in length. General 

 colour above soft rufous fawn, reddening posteriorly into deep ferruginous. An ill- 

 defined blackish band running from the sides of the muzzle backwards to surroun<l 

 the eye; no lighter spot behind the eye. Ears naked. Lips whitish. Under 

 surface bright reddish, the hairs whiter towards their bases. Upper surface of hands 

 and feet whitish. Tail clothed with the woolly rufous body fur for nearly an inch, the 

 remainder brown, scaly, and practically naked as in Ch. forhesi; the smooth prehensile 

 terminal portion just as in the older-known species, i'alate-ridges and mammae as 

 in Ch. fwbeai. 



Skull on the whole fairly similar to that of Cli. Jorbcui. The jieculiar riglil- 

 angled spring of the anterior zjgonia root is, however, less strongly marked; I he 

 upper profile is more bowed, an efi'ect which is increased b\' the supraorliital edges 

 being more developed vertically. Palate ending opiiosite the middle of, instead of 

 behind, the last molar. 



Molars rather broader and heavier than in Ch. favbesi ; their iiatteni on the whole 

 very similar, but there appears to be a tendency to an even gi'eater crenulation of the 

 cusps and ridges. 



Dimensions of the tyjie, an adult male in spirit : — Head and body 153 mm. ; tail 

 225; hind-foot 33"; ear 17'3 x 12-1. Skull, basal length 34-5 ; greatest breadth 

 225; nasals, length 12; interorbital breadth 6; interparietal, length 47, breadth 

 111 ; palate, length 18-5 ; palatal foramina 5 ; diastema ir2 ; length of upper moliir 

 series 5"7.

This very beautifully coloured Kat is a most interesting discovery, as no rejire- 

 sentative of the genus Chiruromys has been met with, so far as I know, since my 

 description of the genus and typical species seven years ago.* That ty])ical species, 

 Ch. forbeai, came from Sogere in the Owen Stanley Mountains, S.K. New Guinea, and 

 the discovery of a different but allied species in the D'Entrecasteaux Islands is therefore 

 not unnatural. 



The essential characters of the genus, its peculiar molar-structure, and its 

 prehensile tail have been fully dealt with in the original description, and it need only 

 here be said that Ch. pulcher agrees with Ch. fm-besi in every character of any 

 importance, while its very different coloration shows that as a species it is entirely 

 distinct.
