trudes beyond the margin of tlie jaw, whilst i i is almost fully grown. 

 The true premolars, as well as the canine, are half grown; the milk- 

 premolar, which is quite small, and has a flat crown, still remains 

 criished in on the outside of the advancing p^ . Of the molars, but 

 ?wi is as yet visible beyond the margin of the jaw. 



In the lower jaw, the milk premolar is likewise present, whilst p^ 

 is in the act of breaking through. An anomaly is visible in the left 

 jaw, two equally large p'^ being present, the one before the other, 

 which, however, together are not rauch larger than ^ 2 on the oppo- 

 site side.

B. Herbert Vale, Dec. 1882 (skin with skull). 



C. Upper Herbert River, 24"^ Dec. 1882 (skin with skull). 



This species occurred in N. Queensland, according to Dr. L., in 

 somewhat less number than B. sciureus, although on the whole, they 

 were not scarce. 



Both the fullgrown specimens from Herbert Vale almost perfectly 

 agree with the S. Australian P. Ireviceps, although the upper surface 

 has a somewhat yellower tint, a character, which is just alleged to 

 the N. Australian form P. ariel (which, by recent authors, is likewise 

 recorded. from New Guinea , Batjan , Halmahera , New Britain , etc.). 

 The under surface is, however, not nearly so bright a yellow, as, ac- 

 cording to Gould's drawing (Mamm. Austr. pl. 2), is characteristic to 

 P. ariel; the specimens from Herbert Vale form, on the whole, a me- 

 dium between both forms. 



The young individual (A) on the other band, corresponds most 

 closely to Peters' Belideus notatus (in: Monatsber. Akad. Wiss. Berl. 

 1859, p. 14); it is of the same colour above, and has a broad white 

 tip to its tail ; but the light longitudinal stripe on the tail, which be- 

 longs to this form, is indistinct. 



Besides, concerning the colouring of the individuals, the black 

 stripe on the back in all of them is but slightly visible; especially 

 so on the nape, where it is almost invisible. The tail in all of them
