To the Phalangista maculata, Desm., are referred specimens of a 

 Couscous which the authours had once regarded as the type of a new spe- 

 cies, and to which they had given the name of Cuscu$ chrysocephalus. 

 These differ from the individuals previously known by their large size, 

 their almost entirely woolly fur, and their colours. They possess the 

 small additional false molar in each jaw, which is generally indicative of 

 immaturity in the genus to which they belong. But notwithstanding this, 

 which, in conjunction with their size, would appear to indicate that they 

 were the young of a larger animal than the Cuscus maculatus, MM. Les- 

 son and Garnot regard them as belonging to that species, of which they 

 consider the specimen figured and described by them to be an individual 

 in its complete developement, and in a fine state of fur. It is placed in 

 a section of the genus Cuscv^s, Lacep., " Auriculis brevibus, non dis- 

 " tinctis, intus pilosis," and is thus characterized, " Cuscus major, 

 " corpore lanuginoso subalbido, supra maculis aterrimis sparso. Cauda 

 " prehensili rubra, tubeiculos^. Faciei pilis aureo-ful vis : extremitatibus 

 " supra brunneo-fuscis." Its length to the root of the tail is twentj'-five 

 inches, and that of the tail twenty inches, eleven inches of the latter being 

 naked : the former dimension, it may be remarked, exceeding in an in- 

 dividual with immature dentary characters by no less than seven inches and 

 a half that of M. Temminck's largest adult specimen of his Phalangista 

 maculata. From the anatomical observations appended we learn that the 

 sternum is extremely narrow, being in fact only a slip for the attachment 

 of the cartilages of the ribs : the stomach, which is reniform, occupies the 

 whole of the epigastric region extending a little into the left hypochonr- 

 drium; the pyloric valve is thick and fleshy; the duodenum forms a 

 single curve in front of the vertebrcB ; the small intestines, about nine 

 feet and a half in length, join the rectum perpendicularly; and the 

 coicumh large, with a vermiform appendage seventeen or eighteen inches 

 in length : the liver is divided into five unequal lobes, tw^o of them being 

 much larger than the others, and notched ; the gall-bladder is large, 

 elongated, and placed between the large right lobe and the third in size, 

 by which it is hidden : the spleen is small, elongated, and somewhat 

 triangular : the kidneys are small, and resemble those of the human 

 subject : and the penis is placed behind the scrotum, its glans terminat- 

 ing in a pointed prolongation.
