On a Collection of Mammals from Central and Northern Queensland. 377 



The three mature specimens, the skins of which were brouglit 

 home, were two males and one female, the latter with a large young 

 one, and correspond in all important points with specimens from South 

 Australia. 



In all the hair covering is very thin and short (they were shot 

 during the sumraer months), whilst one specimen in the CJniversity 

 Museum from New South Wales has a close, long and woolly coat of 

 hair. The young one (A) which has not yet finally left its mothers 

 pouch, although nearly of the size of a fox, was coloured like the 

 mother (C). The bones of the skull were loosely connected ; p'^ is, 

 however, still present. 



In all the specimens the outer surface of the ears is uniformly 

 coloured down to the base, without exhibiting a trace of the colour 

 which GouLD, (in: Ann. Mag. Nat. Hist., vol. X, p. 1, 1842, and Mamm. 

 Austr. part XII, 1860) ascribes to his M. ocydromus, or (in: Proc. 

 Zool. Soc. Lond. 1842, p. 10) to his M. melanops.

The two largest males (E and F) and the two largest females 

 (B and C) all represented fully grown individuals, in which the last 

 molar shewed traces of being worn. Nevertheless the frontal crests 

 were diflferent in all. 



In F, the largest of the specimens, they were completely separated 

 in the whole of their course, so that they, without being connected, 

 adjoined the occipital crest. In the next largest male and in the some- 

 what younger male, D, and E, the ridges meet near the occipital crest. 



In the two females (B and C) the frontal crests were separate during 

 their entire course, until they meet close to the occipital crest. 



The skull diflfers from the following species of Halmaturus by 

 the Processus zygomaticus of the os temporale being about equally 

 broad everywhere , while in the Halmaturi it becomes narrower for- 

 wards, and has its greatest height at or behind the centre. 



The orbital margin on the frontale converges evenly towards 

 the back without forming a proc. postorbitalis, and is strongly rounded, 

 as the frontale is rather inflated, and forms a thiuly walled protuberance 

 on the orbital walls.
