premolar somewhat resembles mi, but is a little smaller; its anterior 

 division is rather narrower and has a trace of a (very short) longi- 

 tudinal edge in front of tbe foremost tubercle. 



The lower p i is narrower, and with sharper edges than the upper 

 one. The milk premolar is likewise smaller and narrower, and has, 

 more plainly , than in the upper jaw, the front tubercle extended to 

 a Short edge. 



The skeleton of the mature specimen (E), which is mounted 

 in the Museum of the Christiania University (together with the in- 

 complete skeletons of the other specimens), exhibits the following 

 number of vertebrae: 



C. 7, D. 13, L. 6, S. 2, C. 30. 



On the epistropheus, the processus spinosus in front is short and 

 rounded, but contracted behind. 



The Processus spinosi on the lumbar vertebrae are proportionally 

 low and rounded. 



The OS sacrum is comparatively long, and the two vertebrae, seen 

 from above, are each of about a normal length ; their processus spinosi 

 are very low, and not ankylosed at their base. 



The first pair of costae are remarkably strong and curved throughout 

 their entire length , forming almost an angle, likewise short in com- 

 parison to their strong curvature. 



Clavicula, strong and curved, also, when viewed from the side, 

 bent in the form of an S. 



Spina scapulae, elevated; the acromiou curves itself strongly 

 down towards the clavicula. 



Pelvis, comparatively short, especially ossa ischii, the length of 

 which from the centre of the acetabulum to the angle at their back 

 is equal to the length of the 2 last lumbar vertebrae. 



Femur, tibia and hind foot (to the end of the claw) are exactly 

 equal in length (see measurements). 



The metatarsal bones are flattened, as well as the phalanges ; the 

 2°^ and 3"^^ toes are comparatively long, and extend (claw not in- 

 cluded) forwards to the 2"^ phalanx of the 4''* toe. The 5* toe is 

 comparatively strong and long, and extends with the tip of its claw 

 to the middle of the claw on the 4*^ toe. 



Some measurements of the mounted skeleton are here given: 



Length of skull 111 mm 



Length of body, skull included about 550 „ 



Length of tail (measured from the first tail vertebra) 780 „
