 times and a half; the head is a little broader than high ; the dia- 

 meter of the eye is contained three times or three times and a half 

 in the length of the head ; the width of the interorbital space less 

 than one-half the diameter of the eye. The cleft of the mouth is 

 oblique, with the jaws equal anteriorly ; teeth of the outer series 

 enlarged ; canine teeth none. Dorsal fins lower than the body ; the

 The head is one-fourth less broad, and one-half less high, than long ; 

 the snout is depressed, obtuse, with the lower jaw prominent. The 

 eyes are on the upper surface of the head ; their diameter equals the 

 width of the interorbital space, and is one-sixth of the length of the 

 head. Canine teeth none ; the teeth of the outer series very slightly 

 enlarged. The second dorsal spine filiform, sometimes twice as high 

 as the body ; caudal somewhat pointed ; the upper pectoral rays are 

 silk-like ; the basal membrane of the ventral well developed.

 the length of the head one-fourth ; the head is depressed, with the 

 muzzle broad and rounded ; the diameter of the eye is one-fourth of 

 the length of the head, and equals the width of the interorbital space. 

 The cleft of the mouth is oblique, with the lower jaw slightly ])ro- 

 jecting beyond the upper. Canine teeth none. The middle rays of 

 the anterior dorsal prolonged, as high as, or higher than, the body ;
