572 MR. W. R. B. OLIVER : REVIEW OF THE 



form of the rostrum. On the other hand, the anterior edge of the- 

 tooth in the New Brighton specimen is 15 mm. behind the 

 posterior margin of the mandibular symphysis ; in the Dominion 

 Museum specimen it is about 14 mm. in advance of it. According 

 to my description, the 8th to 10th dorsal vertebrae have the corre- 

 sponding ribs articulated to their transverse processes. Andrews 

 states that the 8th rib of M. boiodoini is articulated to a facet on 

 the posterior margin of the centrum of the 7th dorsal. The 

 superior margin of the acromion in the type of M. howdoini 

 overlaps the coracoid border, whereas it is clear of it in the present 

 specimen.
