canine or, in other words, the snout was constricted behind 

 the canine. Each tooth is elliptical in section, the somewhat 

 longer axis lying in the line of the jaw. The longer axis of the 

 cross-section of the canine is 3.5 mm. long, while the first 7 molars 

 occupy a length of 11 mm. 



In the right ramus of the lower jaw 8 molars are to be seen, 

 each placed directly beside the corresponding tooth of the upper 

 jaw, the teeth of the maxilla biting outside those of the dentary. 

 The point of the tooth is bluntly rounded, and not sharply pointed. 

 It is probable that there were 3 or 4 more molars present in the 

 complete set. The posterior molars are slightly smaller than 

 the anterior ones in both upper and lower jaws. 



There is a faint impression of one of the bones of the palate on 

 the right side having a curved outer border ; the bone is probably 

 thr palatine, forming the inner border of an oval suborbitul vacuity. 

 As preserved the skull is 56 mm. long ; but it was probably some- 

 what longer when complete. The front of the lower jaw was 

 narrow, fairly high, and sloped backwards. 



The neck has almost disappeared ; only traces of the cervical 

 vertebrae can be seen, with the exception of the last. The neck 

 was fairly long and contained apparently 7 vertebrae. The whole 

 skeleton lies in position, and there seems to have been no dis- 

 placement of the neck. If this supposition of 7 cervicals be correct 

 then there are in all 27 presacral vertebrae. The centra of the 

 cervicals are longer than those of the dorsals. Every centrum 

 is constricted in the middle and expanded at the articular ends. 

 In the last cervical the centrum has a longitudinal ventral median 

 keel ; in the dorsals the ventral surface is rounded and very 

 slightly flattened. All the dorsals are very similar in size. None 

 of the vertebrae show the transverse processes or the zygapophyses. 

 Judging from the position of the ribs, the transverse processes 

 were fairly short. There are no intercentra present, nor is it 

 likely that any occurred in life ; the articular surfaces of the centra 

 show no bevelling on the ventral side. 



There are three coalesced sacral vertebrae, of almost the same 

 size as the presacrals. The centra are rounded on their under 

 surface. The last cervical is 7 mm. long. The 3rd dorsal centrum 

 is 6.5 mm. long and has a maximum width of 6 mm. The three 

 sacrals are 6 mm., 6.5 mm., and 6.5 mm. in length respectively ; 

 the anterior end of the first is 7.5 mm. wide.
