CATALOGUE OF MAMMALS FROM NEW GUINEA. 



Skull (figs. 5, 6, 7) depressed, very broad, with very large expanded 

 zygomatic arches ; the face narrow, compressed and nearly erect on 

 the sides, tapering in front ; the palate narrow, concave. The cutting 

 teeth ~ t ; the upper front elongate, projecting in front, rather taper- 

 ing and truncated at the tip ; the second and third compressed, chisel- 

 shaped, close together and to the front ; the second small, the third 

 larger ; the fourth separated from the others by a small space and 

 placed on the intermaxillary suture, compressed, curved rather like 

 a canine ; the lower front very long, projecting in front, curved, 

 rather tapering at the tip ; the second, third and fourth small, trun- 

 cated, separated from each other ; the second largest, close to the base 

 of the front tooth ; the third small, separated from the second by a 

 small space ; the fourth very small, far from the other ; and at the 

 base of the front edge of the first grinder, in the space between the 

 third and fourth on the right side of the jaw, is a cavity which 

 appears to have been filled with a tooth like the third one, but 

 there is no appearance of the tooth or cavity on the other side. 

 Canines? ( ^ ) , upper small, compressed, conical, tapering like, but 

 smaller than, what I have called the hinder cutting teeth (fig. 7). 

 Grinders j^t, small, in two nearly straight lines parallel to each 

 other, and the hinder ones in each jaw rather smaller than the 

 front ones ; the front upper small, triangular ; the others four-sided 

 and square,- with four tubercles, the outer front tubercle of the 

 second tooth being rather larger than the rest, which are nearly 

 equal among themselves, and the front lower grinder has only one 

 larger tubercle in the place of the two in the others (figs. 8, 9). 



This genus is very distinct from the other genera of Phalangistina, 

 in the elongated and depressed form of the tail, the formation of the 

 fore-feet, and especially in the disposition and form of the teeth, as 

 well as in the broad depressed skull.
