which is contained three times and one-third in the length of the 

 head. The pectorals extend to the end of the dorsal, and the ven- 

 trals to the middle of the anal. The insertion of the ventrals is 

 midway between the end of the snout and the extremity of the upper 

 caudal lobes. The origin of the dorsal is far in advance of that of 

 the anal ; it is of moderate height. Coloration of the pectorals uni- 

 form ; dorsal with a large dark blotch.

The height of the body is a little less than one-seventh of the total

 The height of the body is contained five times and a third in the 

 total length (without caudal), the length of the head four times and
