D.12. A’ 13. .V. 6: L. lat..34. -L. transv. 12. 
The height of the body, taken on the level of the base of the pectoral, is two-ninths 
of the total length (without caudal). Head depressed, its length being one-fourth of 
the total. Interorbital space very broad, slightly convex, its width being one-half of 
the length of the head. Snout broad, obtuse, much depressed, with the lower jaw 
scarcely projecting beyond the upper; mandible longer than the eye. Upper lip of 
moderate breadth, not extending to the angle of the mouth. The diameter of the eye 
is less than the length of the snout, two-ninths of that of the head, and less than one- 
half of the width of the interorbital space. The origin of the dorsal fin is somewhat 
nearer to the extremity of the caudal than to the orbit, and corresponds to the nine- 
teenth scale of the lateral line. The first anal ray is opposite to the third of the dorsal. 
Dorsal and anal fins subquadrangular, with the outer margins convex: both are a little 
longer than high. Caudal fin subtruncate, scaly on its basal half. Pectoral fins shorter 
than the head without snout, not extending to the base of the ventrals. Brownish 
olive, paler below, each scale, especially those on the tail, with a vertical dark purplish 
violet spot on the centre. Dorsal with three or four series of blackish dots, anal with 
a whitish margin. 
A single male, 34 inches long, was obtained by Mr. Salvin at Chiapam.

D.12 (13). A. 14-15 (16). L. lat. 32-35. L. transv. 12. 
The height of the body, taken on the level of the base of the pectoral, equals the 
length of the head, and is one-fourth or rather more than one-fourth of the total length 
(without caudal). Head thick and broad; interorbital space broad, slightly convex, its 
width being a little less than one-half of the length of the head. Snout broad, obtuse, 
with the lower jaw slightly projecting beyond the upper; mandible longer than the eye. 
The diameter of the eye is equal to, or, in the larger specimens, less than the length of 
the snout, one-fourth of that of the head, and one-half of the width of the interorbital 
space. ‘The origin of the dorsal fin is midway between the extremity of the caudal and 
the posterior margin of the orbit, and corresponds to the nineteenth scale of the lateral 
line. The first anal ray corresponds to the second of the dorsal. Dorsal and anal fins 
subquadrangular, rather low, longer than high in the male, and as long as high in the 
female. Two-thirds of caudal covered with small scales. Brown above and on the 
sides, pale below; females with a very indistinct dark band along the side. Fins 
immaculate; anal with a light margin. 
The sexual opening of the female is not attached to the anterior anal rays
