1866.] DR. G. HARTLAUB ON A NEW CRATEROPUS. 435 



narrow as in Dasyurus ; the first pair directed forwards, and slightly 

 longer than the others. Premolars three in the upper jaw, the 

 middle one largest, the first somewhat smaller, and the third and 

 last very diminutive and tubercular. Molars of the usual triangular 

 form, with rather blunt tubercles, increasing in size from the first to 

 the third, the fourth being narrow and transverse. The lower jaw is 

 short and strong, and the articulating condyle placed still higher 

 comparatively than in any other species of this group. The incisors 

 are three in number, the first pair being the largest. Canines smaller 

 than those of the upper jaw, but sharp and pointed, without the 

 broad base common to other small Dasyures. Of premolars only 

 two are found in the lower jaw, the second larger than the third. 

 There are four molars, the first and last being the smallest, the two 

 middle ones of about equal size ; on the first the anterior tubercle is 

 scarcely indicated, showing, with the absent third premolar, a close 

 approach to the genus Dasyurus. Tail thick, compressed, with a 

 crest of black hair upon the apical half, similar to the tail of Ckce- 

 ropus. 



1. Ch.etocercus cristicauda, sp. nov. (PI. XXXVI.) 



General structure similar to that of Phascogale calura ; limbs 

 strong, furnished with long claws ; five toes to the fore and hind 

 feet, the inner toe of the latter a short nailless thumb ; the hair upon 

 the fore feet is very long and shaggy. 



General colour a leaden grey at the base of fur, tipped with sandy 

 and rufous. Tail : basal portion reddish, darker towards the tip. 



Total length 8 inches, tail 3^, head to base of ear 1, tarsi and 

 toes 1-J-. 



Hub. South Australia, probably the neighbourhood of Lake Alex- 

 andria. 



The Australian Museum received a specimen of this animal, which 

 is not in very good condition, from Fr. G. Waterhouse, Esq., of the 

 Institute Museum, Adelaide, a gentleman who has done much to 

 investigate the fauna of South Australia.
