 Fam. Pteropodidae. 



7. I^eropus poUocephalus Temm. 1827. 



P/erupus poUocephalus Temm. Mouogr. Mammalog., Tom. 1, p. 179 



(1827). 



A. Female, Seaforth, Mackay, 19. July 1882 (skin with skull). 



B. Seaforth, Mackay, 19. July 1882 (skeleton). 



Is found in great numbers at Mackay and at other places in 

 Central Queensland. Length of Cubitus : A. 142 mm, B. 143 mm. 



The skull. 



Length of skull A 61 mm, B 66 mm 



Breadth across zygomatic arches „ 29 „ „38 „ 



Sagittal crest completely wanting, although one of the spe- 

 cimens (B) appears to be füll grown. Two low crests extend back- 

 wards from the postorbital processes, which converge slightly po- 

 steriorly, but these have already entirely disappeared at the Sutura 

 coronalis. 



The skull of A, belonging to the younger specimen, is relatively 

 narrower across the zygomatic arches, as these run almost parallel, 

 whilst in B they converge in front. The processus postorbitalis is 

 also naturally shorter; the orbital crests are moreover in this spe- 

 cimen almost parallel. 



The dentition in both is normal: i| e\ p^ m| (34). 



The number of the teeth is complete in both specimens, and the 

 rudimentary upper p ^ is present, although it scarcely extends beyond 

 the gums in the living animal. The crowns of the teeth are not 

 coloured. 



In the Upper jaw both the innermost molars are placed a little 

 out of the series, compared with the premolars, so that the inner 

 margin of m ^ does not keep in the same line as the inner margin 

 of /) 2, but points towards the centre of this tooth. 



In the lower jaw there is a distinct space between the two first 

 incisors, which is greater than in Tt. gouldii. 



In the younger specimen the right upper canine is so deeply 

 grooved, that the tooth is completely divided into two closely united 

 halves.
