but without larger canines near angle of mouth ; those on symphysis 

 like those on side, but a little smaller ; no teeth on vomer and 

 palatines ; tongue broad, slightly rounded or truncate at tip. Maxillary 

 extending to vertical from antrior rim of orbit, entirely concealed under 

 preorbitai and lip. Anterior nostril with a long tube ; posterior nostril 

 w ithout it. No barbel on chin ; cheeks slightly tumid. Gill-opening 

 lateral ; isthmus broad, slightly shorter than postorbital part of head ; 

 gill-rakers on first gill-arch 7+10 in number, stumpy, very short; a 

 large slit behind last gill ; pseudobranchiae developed. Two dorsals 

 well separated from each other though by a short space. Origin of 

 first dorsal midway between tip of snout and posterior end of base of 

 second dorsal, or above the beginning of the second half of pectoral. 

 Origin of second dorsal nearer to caudal base than to posterior rim of 

 eye by length of snout. In the first dorsal the third or fourth spine 

 longest, equal to postorbital part of head, outer margin rather rounded, 

 with the membrane between spines distinctly scalloped. Second dorsal 

 slightly lower than the first, the highest ray being' the sixth ; the 

 margin broadly rounded, but scarcely scalloped. Anal immediately 

 behind vent, inserted below fourth ray of second dorsal ; rays highest 

 behind the middle part but somewhat shorter than the rays of second 

 dorsal ; the edge rounded, but not scalloped ; both vertical fins 

 not reaching to caudal base when folded backward. Pectoral rather 

 large ; no papilla on inner edge nor filamentous appendages above ; 

 rounded posteriorly, extending beyond vent. Ventral rather small, 

 free to base, not reaching to vent, distance between tip of ventral 

 and vent slightly less than one-half the distance between the 

 former and the orgin of ventral. Caudal rounded. Anal papilla well 

 developed. Scales rather large, finely ctenoid ; nape closely covered 

 with smaller cycloid scales, but occipital parts naked. Throat before 

 ventral with a very few number of small cycloid scales ; breast behind
