The skull simUar to the former, so similar that it is not easy to 

 point out any difference in words. The teeth are rather more 

 numerous, viz. jg^, rather smaller, being six in an inch length of 

 margin. 



The hinder part of the palate, in front of the inner nasal opening, 

 narrower and very sharply keeled on the sides ; the sides of the 

 narrower and shallower central groove convex, smaller, and the 

 outer sides of the keels concave and shorter. 



The bladebone not so much produced behind the ridge, and with 

 an oblique hinder margin, without any truncation at the lower part. 

 The coracoid process is similar, but broader iu the middle of its 

 length, the lower edge being nearly straight.
