The height of the body equals the length of the head, and is con- 

 tained thrice and two-thirds in the total length (without caudal) ; 

 males have the body comparatively shorter. Snout rather obtuse, 

 the mandible being directed obliquely upwards. The diameter of 

 the eye is two-thirds of the length of the snout, one-fifth of that of 

 the head, and rather less than one-half of the width of the inter- 

 orbital space, in large specimens ; in younger examples the snout is 

 shorter. Dorsal and anal of moderate size, higher in males than in 

 females. The origin of the dorsal is midway between the extremity 

 of the caudal and the anterior margin of the orbit in females, but in 

 males it is exactly in the middle of the total length ; it corresponds 

 to the seventeenth scale of the lateral line ; it is distinctly in ad- 

 vance of the vertical from the base of the anal, the first anal ray 

 being below the fourth of the dorsal. Coloration uniform (in spirits). 



The opening tube of the oviduct is attached to the anterior rays 

 of the anal fin.

Specimens, two inches long, sent by Prof. Agassiz under the name 

 of Fumhdus spihtus (Holbr.), to the Liverpool Free Public Museum, 

 appear to me to be the young of F. heteroclitus ; they are obscurely 

 spotted on the sides, and have a black dot in the middle of the last 

 dorsal rays.

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

 length (with the caudal), the length of the head a little less than 

 one-fourth. The diameter of the eye equals the length of the snout, 

 and is one-fourth of that of the head. Origin of the dorsal fin mid- 

 way between the extremity of the caudal and the end of the snout ; 

 origin of the anal fin opposite the middle of the dorsal. Fins small. 

 A black stripe on the middle of the side, from the anterior third of 

 the body to the base of the caudal. (Gir.)
