Genus 30. ENCHELYCORE, Kaup. 



The widely-cleft jaws (as is the case likewise in Enchyhjnassa) 

 cannot close on account of the length of the teeth. The hinder 

 nostril is also big, is situated before the eye, is longer than it is 

 broad, and measures from half to three-fourths of the diameter of the 

 eye, while the fore nostril-tube is unusually short, does not project 

 beyond the lip, and is not furnished with a lid. The eye is situated 

 in the middle of the snout, and the slender mandible is somewhat 

 curved upwards at the end. On the outer border of the nasal 

 bone there are 24 fine teeth, whereof only the first, sixth, and 

 tenth are elongated ; 8 longer movable ones in the second row, 

 equalling in height the 3 on the mesial line. Palatines, 18, with 3 

 bigger ones ; in the second row, 5 big movable ones. Vomerines, 

 15-16, small and pointed. Mandibulars, 37, the foremost 2 bigger, 

 the others fine ; in the second row, near the symphysis, 2 bigger, 

 movable teeth.
