186 PHALASaEEID^. 



striated pads ; soles thickly hairy under the heels ; the rest naked, 

 ■with low rounded pads, not sharply defined. Tail thick, evenly 

 bushy to its end, not tapering, its terminal third or half with a 

 naked line beneath; its extreme tip naked all round. A gland 

 present on the chest. 



Skull stout and heavily built. Nasal notch shallow. Porehead 

 flattened. Supraorbital edges ridged, not inflated. Palate im- 

 perfect. BuUsB low and flattened, scarcely inflated. Base of 

 masseteric fossa with no trace of ^n opening into the inferior 

 canal.

Upper incisors very uniform in length ; i.' exceeding the others at 

 most by about a millimetre, its anterior surface flattened ; its inner 

 terminal corner touching that of its fellow of the other side. 

 Canine situated some way from the back of i.', emerging from the 

 bone partly or even wholly in front of the premaxUlo-maxillary 

 suture ; its length generally less than, at most barely equalling, that 

 of i.^ P.' present or absent; if present, sufiiciently large to be 

 functional; p.° whoUy absent; p.* large, obliquely set, its anterior 

 end turned outwards, its cutting-edge indistinctly ridged, as in the 

 Maeropodidce, but these ridges only visible when the tooth is 

 unworn. Molars quadricuspid, the cusps tending to form transverse 

 ridges. . Lower anterior incisors large, less spatulate and less 

 horizontal than in the previous genera. I.^ proportionally larger 

 than usual, and apparently always persistent ; other intermediate 

 teeth generally altogether absent, sometimes represented by a single 

 minute one (probably p."). P.* large, obliquely placed, and ridged, 

 not dissimilar to that of Hypsiprymnodon. Molars similar in 

 character to those in the upper jaw. 



Range. Australia and Tasmania. 



This genus, while widely different from Pseudochints in its 

 cranial and dental characters, is yet not easily deflnable externally. 

 Its fore feet, however, appear to be of more normal construction 

 than in that genus, its tail is more densely haired terminally, 

 although in this character it is approached by Pseudochints lemu- 

 ■roides, and, in most specimens, the discoloration of the fur caused 

 by the chest-gland forms an easy method of recognizing its 

 members.
