of first ray of pectoral 20.4 (19.0) ; length of longest pelvic ray 15.9 

 (16.7); length of longest anal ray 15.0 (15.1) ; length of longest ray of 

 upper caudal lobe 30.3 (30.0); length of longest ray of lower caudal 

 lobe 24.7 (27.1) ; shortest midcaudal ray 9.36 (9.82) ; distance from tip 

 of snout to dorsal origin 36.7 (36.9); snout to anal origin 72.6 (71.5); 

 snout to adipose origin 66.1 (66.4); snout to pelvic insertion 47.2 

 (45.8); snout to pectoral insertion 26.2 (25.8); snout to anus 53.5 

 (51.4); anus to anal origin 19.6 (19.2) ; length of maxillaty barbel 73.4 

 (79.4); length of outer mental barbel 29.6 (32.7); length of inner 

 mental barbel 14.6 (16.8); distance across ends of premaxillary band 

 of teeth 9.36 (9.35); diameter of bony orbit 5.69 (5.98). 



The following counts were made: Dorsal i, 6 (i, 6) ; anal v, 9 (v, 10); 

 pectoral i, 13 (i, 13); pelvic i, 5 (i, 5); branched rays in caudal fin 15 

 (15); gill rakers — (3 + 10). In addition the following counts were 

 made: Anal v, 8 in one fish, v, 9 in nine specimens; pectoral i, 14 in 

 six examples, and i, 13 in four; gill rakers 2 -\- 10 in one fish, 2 + 11 

 in another, 3 + 11 in two, and 3 + 10 in five specimens. 



Dorsal surface of head depressed anteriorly; ventral contour nearly 

 straight, the lower surface flattish so that the upper lip is on same 

 plane as lower jaw, the snout projecting a distance equal to diameter 

 of eye; supraoccipital process with a narrow base and projecting 

 backward a distance about equal to eye and not meeting the predorsal 

 plate; premaxillary band of villiform teeth wide, teeth depressible; 

 band of villiform teeth at front of dentaries; no teeth on vomer or 

 palatines; interorbital space slightly concave or flattish; gill rakers 

 not quite so long as pupil; adipose fin high, its height about 3.8 to 

 4 in its length; space between base of dorsal and adipose origin a little 

 greater than length of snout and eye; adipose fin base twice length of 

 anal fin base; adipose fin contained 4}2 to 4:% in standard length; 

 posterior margins of dorsal, anal, and pectorals a little concave; 

 pelvics rounded; caudal fin deeply forked, the upper lobe a little longer 

 than lower; length of caudal peduncle 1.2 in adipose fin length; frontal 

 fontanel extends to opposite rear margin of eye, this fontanel bordered 

 by two small cartilaginous ridges that converge forward and then ex- 

 pand at front of snout; nasal cavities bordered by a black cartilaginous 

 rod at sides and anteriorly; occipital fontanel minute; center of eye in 

 middle of head; first ray of dorsal and of pectoral simple, articulated, 

 and not spinous, these rays a little longer or equal to the first branched 

 ray; barbels somewhat flattened anteriorly, the maxillary one in 

 young reaching to caudal fin but in larger specimens only to end of 

 adipose fin; outer mental barbels with base farther back than inner 

 mental barbels, and reaching in young to pelvic insertion but only to 

 pectoral insertion in those about 150 mm. in standard length; inner 

 mental barbels reach to or almost to pectoral insertion ; gill membranes 

 extend forward and are free from the isthmus.
