The shape of the body is similar to that of the northern moon- 

 eye. The belly has a slight but obtuse keel in front of the ven- 

 trals and is compressed to a rather sharp edge behind the 

 ventrals. Head short, its length two ninths of total without 

 caudal; the eye much longer, about one third the length of head. 

 The greatest depth of the body is nearly one third of total 

 length. The pectoral is as long as the head without the snout; 

 the vi-ntral not much more than two thirds the length of head, 

 its origin under the ISth scale of the lateral line. The anal 

 origin is uni^ Tth developed ray of the dorsal. The longest 



anal ray is less than one half the head. The anal base is as 

 long as the head; iis last rav is less than one half the longest
