■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.

According to the description, E. albidactyhis (Gill) would appear

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

 diameter of the eye is contained three times and one-third in the 

 length of the head ; interorbital space somewhat concave. Teeth 

 longer than usual. Dorsal fin low, and nearly of equal height. Pec-

 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 

 a third. The depth of the head equals the distance between the ex- 

 tremity of the snout and the hind margin of the orbit. Snout some-
