body 5 to G in the total length; depth of head 2j-\j- to 21 ((^), 2|- 

 to 2i (g), widtli of head If to U (S), If to 1| (g;, of iuter- 

 or])ital region i'r^ to 4;} (^), 5 to 5| (g), diameter of eye 4| to 5i 

 in the length of the head; snout broad, rounded in front, and 

 much depressed, one-half to tliree-fifths of a diameter longer tlian 

 the eye. Maxillary extending to the vertical from the posterior 

 margin of the eye (q), the middle of the e^^e (g), its length 

 l/o to I'f iS), '^ to 21 (9) in that of the head. The teeth of the 

 inner series are the largest, those preceding them growing 

 gradually smaller. Eleven or twelve gill-rakers on the lower 

 l)rancli of the anterior arch. The space between the origin of the 

 first dorsal fin and the extremity of the snout is greater than its 

 distance from the base of the last soft ray; outer margin of the 

 spinous dorsal convex, the second or thiirl ray the longest, 2i to 

 2h in the length of the head, and reaching when laid back in the 

 ^ to, in the 9 not so far as the origin of the second dorsal; in 

 the (J the seventh and eight soft rays are the longest, 1^ to If, 

 in the 9 the third and fourth are the longest, 2^^ to 2^ in the 

 length of the head : the anal fin commences a little behind the 

 origin of the second dorsal and is in all respects similar to it : 

 fourth venti-al ray not greatly produced bej'-ond the third or fifth 

 and not nearly reaching to the vent in either sex, its length 14 to 

 1-| in that of the head: middle pectoral ra3's the longest; they are 

 in the ^ much longer than the fourth ventral ray, I'eaching well 

 beyond the vertical from the origin of the second dorsal, and 1-|- 

 to 1 ^- in the length of the head, in the 9 subequal to tlie fourth 

 ventral ray, reach to or not quite to the vertical from the dorsal 

 interspace, and IJ to 1§ in the head : caudal rounded, 1^- to 1-^- 

 in the length of the head; the peduncle rathai" slender, not differ- 

 ing appreciably in l^oth sexes, its length If to If in that of the 

 head, its depth 2.V to 2'^ in its length. G-enital papilla very small 

 and triangular in the ^, ol)long and notched in the 9, in which 

 it is somewhat larger. Scales small and irregular anteriorl)'; 

 those on the tail with an angular border; occij)ital scales small, 

 deeply embedded, and non-imbricate, extending forwards almost 

 to the eyes.
