3. RH1NOPTERA. 



Snout deeply divided by a mesial notch. The cranial-fin does 

 not lie in the same plane with the breast-fin, but more beneath, and 

 it is joined to the under root of the breast-fin. Moreover, the rays 

 of the cranial-fin begin wider behind than the rays of the breast-fin 

 end. The under edge of the nasal-flap straight ; its outer angle 

 pointed. On each side of their dorsal surface is a longitudinal fold. 

 The borders of both jaws straight. The teeth stand in from three 

 to five rows of broad six-cornered crowns, near to one another, and 

 diminishing in size towards the sides. Moreover, on the outside is 

 a smaller row, which is not broader than long : they occupy the 

 whole breadth of the jaw.
