 depth of the body nearly as great as the length of the head, and 

 contained in the total length of the body about 8f times. Eyes 

 superior and slightly anterior in position, about 6|^ in the head, 3 

 in the snout and 1^ in the maxillary. Posterior margin of maxil- 

 lary about midway in the space between the tip of the snout and 

 the front margin of the eye. Upper and lower profile lines of 

 the head sloping anteriorly in the form of an isosceles ti'iangle, 

 when viewed laterally, with the mouth at the apex. Interorbital 

 space convex, about If in snout and a little over 4 in the length of 

 the head. The eye is 1^ in the interorbital space. Head entirely
