42 CLASS MAMMALIA. 



side of the limbs are rather of a more obscure colour than 

 the back. The tail is covered with hair in its entire extent, 

 with the exception of a narrow band placed underneath, 

 which commences about the middle, and continues to the 

 point. The skin which covers this band is slightly granu- 

 lated. The hairs of the tail are long, and of a very fine 

 black, except at the base, where they are of the same 

 colour as the back. 



The females are similar to the adult male. Young males 

 are of a gray colour, similar to that of the small gray squir- 

 rel, on the upper parts of the body and external face of the 

 limbs. The ends of the feet are reddish. The muzzle is 

 of a clear colour, bordering on soiled white. Under part 

 of the body is of a yellowish dirty white. The tail is gray 

 at its base, like the back, and grows progressively deeper 

 towards the extremity, which is quite black. The upper part 

 of the tail is marked with a narrow, black, longitudinal 

 line, very distinct, extending to the point, and beginning 

 about an inch and a half from the origin. 



The entire number of teeth in this species is eight and 

 thirty. The upper canine is not much pointed, and rather 

 resembles a false molar than a true canine. It is followed 

 after an interval by another small conical tooth, which 

 itself is distant from the molars. These last are six in 

 number, four true and two false. In the lower jaw, on the 

 bar which separates the incisors from the molars, are two 

 small teeth. There are five molars, one of which is false. 



According to Mr. Roll in, surgeon of our naval establish-

 sists on small prey, and chases the birds like the Didelphes. 



Its habitat is the eastern coast, in the environs of Port 

 Jackson. 



The Phalanger of Cook, (Phalangista Cookii,) is about 

 one foot two or three inches long. The tail is nearly equal 

 in length to the whole body. The upper part of the body
