Both the larger specimeDS are füll grown; the species is easily 

 distinguishable by the distinct black stripe on the back, The male 

 (B) exhibited a peculiarity in its colour. On the hind portion of the 

 back, below the termination of the back stripe, three distinct trans- 

 verse bands are seen (not unlike the stripes in Myrmecohius). The 

 Upper band is short. and is situated close to the dorsal stripe; the 

 others are louger. All are black, with an equally broad lighter raargin 

 underneath i). 



Some measurements taken from the mounted male (B) give: 

 Length of body (head included) about ? 



Length of tail 468 mm 



Length of ear (measured along its inner margin) ... 68 „ 

 Length of hind foot (from heel to tip of claw) . . . 187 „ 



The ears are of medium length, their height somewhat less than 

 the distance from their inner margin to the angle of the mouth. The 

 tail is comparatively long. Thus is contained in the male spe- 

 cimen (B): 



the ear in the length of the hind foot 2,75. 



the skull in the length of the hind foot 1,59. 



the hind foot iu the length of the tail 2,50. 



The skull: 

 B. Length 117 mm, Breadth 61mm, Length of lower jaw 88 mm

No sagittal crest ; the frontal crests meet just at the interparietal 

 bone, and are very low on the parietalia, or (in C) even appear as 

 shallow grooves. The orbital margins are almost parallel in front, 

 until a Short protuberance is formed as an indication of a postorbital 

 process. 



The foramina palatina are large, and the bony bridge behind 

 them is scarcely higher, than the diaraeter of the innermost molar. 



The condylus of the lower jaw is slightly Qoncave. 



The teeth. The dentition is normal in both of the mature 

 specimens : 



* I, i) I, m i (28). 



In the Upper jaw the central incisor is strongly eraarginated, 

 running into an anterior sharpe and narrow lobe. «^ is very small, 



1) This instance is not without interest, as it shows, that these trans- 

 verse stripes, so well known amongst several of the Marsupiais, may 

 occur occasionally and individually in genera, in which they are else- 

 where unknown.
