left side with the left mandible. Of the vertebrae there are impres- 

 sions of a few cervicals, imperfect impressions of a number of dorsals 

 with ribs, and well-preserved casts of many caudals with chevrons. 

 There are also seen impressions of a few abdominal ribs. The shoulder 

 girdle is represented by a well-preserved cast of the interclavicle, 

 both precoracoids, and the right coracoid. There are also evidences 

 of both clavicles and both scapulae. The left humerus is some- 

 what imperfect, but otherwise the limb is almost complete, all details 

 of the carpus and manus being beautifully preserved. Of the pelvis 

 most of both pubes and ischia are preserved, and of the hind limbs 

 the left femur, tibia, and fibula, and some remains of the foot. In 

 specimen B the remains are of a slightly larger individual. There is 

 no trace of the head, and only of a very few of the upper vertebrae, but 

 there are impressions of a large part of the very long tail and of a 

 number of abdominal ribs. The left fore limb is nearly perfect, the 

 carpus and phalanges being well shown. Part of the pelvis and of 

 one hind limb are preserved, but not very satisfactorily. 



Though it is to be regretted that no light can be thrown on the 

 temporal region of the skull and on the palate, much of interest is 

 revealed in the impression preserved. In general shape the skull 

 has probably been something like that of Palceohatteria. The snout 

 has been short and the orbit large. 



The maxillary bone is somewhat triangular in shape, and forms 

 the greater part of the side of the face. Posteriorly it extends to the 

 plane of the middle of the orbit, lying underneath the jugal. As pre- 

 served, there are evidences of ten small teeth, which are subequal 

 and simply pointed. There is evidence of dental replacement, as in 

 most reptiles. The anterior part of the bone is imperfect, but the 

 evidence, so far as it goes, is against there having been an enlarged 

 canine.. The premaxillary bone is preserved, but imperfect. It 

 supports at least two simply pointed teeth, which are rather larger 

 than the maxillary teeth. The jugal, so far as preserved, is a slender 

 bone which forms the suborbital arch. The lachrymal only forms a 

 small part of the face, and above ^t lies a somewhat larger bone — 

 presumably the prefrontal. 



The orbit is of large size, and is supported by a large number 

 of sclerotic plates. Of these there have probably been between 

 20 and 24. 



The lower jaw is fairly complete. The dentary is well developed, 

 and though nearly uniform in depth is slightly more developed in 

 front. One small-pointed molar is preserved, biat probably there 

 have been as many as in the maxilla. Posteriorly the jaw is not 

 unlike that of the Anomodonts. There is no distinct coronoid
