notochordal, but the connecting canal in the centre of the body is 

 very small. The ribs are slender and appear to articulate low down 

 and to be single-headed. 



The shoulder girdle is fairly well preserved. The interclavicle is 

 of large size. The anterior part is probably semicircular, but is not 

 well displayed. The posterior median portion is very long and 

 narrow. The clavicles are large and curve round in front of the scapulae. 

 The scapula, coracoid, and precoracoid are so completely anchylosed 

 together that it is impossible to determine the limits of the elements. 

 The scapula is apparently short and broad. Behind it is thickened 

 and rounded, but the anterior portion is thin. The coracoid is short 

 and broad, and posteriorly it terminates abruptly as if for articula- 

 tion with the sternum. The precoracoid is large and flat. There 

 is a fair-sized oval foramen in what is probably the precoracoid. 



There is no trace of the anterior limbs. 



Of the pelvis the pubes and ischia are fairly well preserved and 

 are of the typical plate-like type. The pubis, so far as displayed, 

 appears to be somewhat quadrangular in shape. At the symphysis 

 the inner parts of the two bones lie in nearly the same plane. The 

 outer and anterior corner of the pubis is bent downwards as in 

 Howesia and Erythrosuchus. There is a fair-sized pubic foramen 

 in the posterior part of the bone. The ischium is very much like 

 that in Howesia. The symphysis is apparently complete from the 

 front of the pubes to near the posterior end of the ischia. 



The femur is a moderately stout bone, nearly straight, and with 

 a rather enlarged upper end. Though there has been a pad of 

 cartilage on the head of the bone it has not been thick. There are 

 no remains of the other bones of the hind limb. 



Abdominal ribs are well developed over the whole abdominal 

 region. There seems to be a long median piece with a lateral piece 

 on each side ; and there are probably four series to each vertebra. 



In the dorsal region and possibly also in the cervical there are a- 

 large number of dermal ossification^. These are little bony particles, 

 the largest of which are smaller- than a hemp-seed, and the smallest 

 about a third the size of the largest. They appear to be confined to 

 the vertebral region, and have apparently been fixed in the integu- 

 ment at a little distance from each other. 



The following are some of the principal measurements : — 



Probable length of animal from snout to back of pelvis ... 270 mm. 



Length of mandible (about) 55 



Length of interclavicle (about) 50 



Length of femur 49
