Skull (figs. 5, 6, 7) depressed, very broad, with very large expanded 
zygomatic arches ; the face narrow, compressed and nearly erect on 
the oe tapering in front ; the palate narrow, concave. The cutting 
teeth + = ; 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 re ee of the tooth or cavity on the other side. 
Canines? — —? upper small, compressed, conical, tapering like, but 
smaller one what I have called the hinder eutting teeth (fig. 7). 
Grinders + a small, in two nearly straight lines parallel to each 
other, ial 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.
