snout, measured around from its tip to front of eye, 2^ ; width 

 of mouth 2; interorbital space 1%; space between front of 

 mouth and tip of snout 2 in its width ; front margin of first dor- 

 sal about I ^ in head ; base of first dorsal about i ^ ; front 

 margin oi second dorsal 3V7 i base of second dorsal 3^; front 

 margin of anal 39'^;.base of .anal 4%; least depth O'f caudal pe- 

 duncle 434 ; front margin of lower caudal lobe i ; pectoral along 

 upper margin i ; width of pectoral at base 2^/^ ; front margin 

 of ventral 3^ ; length of ventral 2^/1. Body elongate, de- 

 pressed, and trunk tapering back long and rather slender from 

 base of pectoral, at which point its greatest depth. Edges of 

 body dorsally and ventrally evenly convex, and without a median" 

 depression. In profile contour similar above and below, with 

 pharynx robust and cylindrical. Caudal peduncle rather cylindri- 

 cal, comparatively slender, and its least depth about half its 

 length. At origins of both caudal lobes a transverse crescentic 

 pit. Head large, very robust, greatly depressed, though perhaps 

 a little more evenly convex and less flattened below. Profiles 

 similar, and when viewed above edge is seen as very broadly 

 convex. Snout very broad, depressed, its margin not very tren- 

 chant, and its length about half its width. Eye small, lateral, 

 and near first third in length of head, evidently elongately ellip- 

 soid. Mouth very broadly and evenly convex, its length about 

 half its width, and symphysis forms about last fifth in length of 

 snout as measured to eye. Teeth in jaws all finely serrated along 

 margins, and with very inconspicuous cusps, if present. Upper 

 teeth all broad, and lower ones about half as wide. An evident 

 pit at each corner of mouth, though no' folds. Nostrils rather 

 small, inferior on snout about half way in its length, and with 

 but small flaps. Internasal space wide, about half of interorbital, 

 and latter broadly, though rather evenly convex. Gill-openings 

 5, last 2 over base of pectoral, and third longest, about 3 in in- 

 terorbital space. No spiracle. Body covered everywhere with 

 minute shagreen denticles, not very rough tO' touch. Around 

 superior edges of snout are many minute pores. Origin of first 

 dorsal about opposite first ^/i in space between origins of pec- 

 toral and ventral, or much nearer tip of snout than origin of 

 second dorsal, fin high, its apex just after its pOiSterior basal
