Length of head 2,1, depth of body i^^ in the total length;* 

 depth of head 1^, width of head '2'i in its length. Eye very 

 large, situated on the upper half of the side of the head, its 

 diameter one-third of the length of the head; snout obtuse, shorter 

 than the eye; interorbital region flat, its width 3f in the length 

 of the head. Maxillary not quite extending to the vertical from 



* In this aad all future papers the t jtal length, as taken in connection 

 with the comparative measurements^, is tne distance between the extremity 

 of the jaws and the base of the caudcd tin, unless special mention to the 

 contrary is made; in giving the length oi the fish this fin is of course 

 included. In taking the measurement of the head the free opercular flap 

 is not included, nor, unless definitely stated to the contrary, such portion 

 of the lower jaw as may project beyond the upper.
