908 ROBERT COLLETT, 



The skeleton. 



Some measurements taken from the skeleton (A) are here added: 



Length of skull (to end of nasalia) 64 mm 



Width across the zygomatic arches 34 „ 



Length of dental series in upper jaw 15 „ 



Length of lower jaw to base of incisors .... 40 „ 



Length of dental series in lower jaw 14 „ 



Length of scapula 35 „ 



Breadth of scapula 15 „ 



Length of humerus 39 „ 



Length of ulna 52 „ 



Length of radius 46 „ 



Greatest height of pclvis 52 „ 



Greatest breadth of pelvis (across the ends of ossa ilii) 36 „ 



Breadth across both tuberös, ischii 31 „ 



Height of Symphysis of pelvis 21 „ 



Length of femur 62 „ 



Length of tibia 69 „ 



Length of fibula 67 „ 



Length of bind foot (to end of claw of the 4"' toe) 61 „ 



Length of hallux (without claw) 12 „ 



The scapula 1) in its shape agrees bettor with the scapula of the 

 Petauri, than of the Hypsiprymni, as the spina (as in Petaurista 

 volans) divides the scapula into two, almost equally large portions, 

 whilst in Aepyprymnus rufescens the infra-spinal portion is about 3 

 to 4 times larger than the supra-spinal. 



Also the outline of scapula is almost the same, as in Petaurista. 

 Its back margin continues past the terminal point of the spina as a 

 very rounded line, whilst in Aepyprymnus^ at this point, the line 

 forms an angle. The lower margin is nearly straight, and only exhibits 

 an almost imperceptible curvature in the middle. The Collum is com- 

 paratively broad, at the narrowest part 7 mm, m equal to almost half 

 the greatest breadth of the scapula. 



The Processus coracoidcus is, on the contrary, as in Aepyprymnus^ 

 Short, but distiuct, and rises barely 2 mm above the fossa glenoidahs. It 



1) Only the left is present, and of this the front portions of the 

 spina and the acromiou are broken otf.
