flat; snout 4.12, blunt at tip, not projecting beyond tip of upper 

 jaw, its height at this point above premaxillary about 0.5 its 

 length, a small protruding tubercle at its extreme tip, traces of 

 lateral tubercles; nostrils close to eye, anterior circular, posterior 

 slit-like; suborbital about 0.75 diameter of eye in width; median 

 ridge indistinct, not reaching angle of preopercle; mouth large, 

 slightly oblique, tip of lower jaw included; maxillary 2.35, barely 

 reaching vertical to posterior margin of pupil; mandibular barbel 

 large, equal to diameter of eye in length; upper jaw with an outer 

 row of small canine-like teeth and an inner villiform band of small 

 teeth, a single row of small canines and an outer series of smaller 

 irregularly set teeth on mandible, mandibular teeth smaller, in about 

 three series in front of mouth, narrowing to a single row posteriorly, 

 bearing a strong resemblance to the arrangement found in species of 

 Chalinura, no teeth on vomer or palatines; gill membranes attached 

 to isthmus; opening of last gill-slit small; scales large, distinct, 9 

 rows from insertion of dorsal to and including lateral line, 7 rows 

 from last ray of first dorsal, 34 between middle of dorsal and vent; 

 free portion of each scale armed with well-developed spinules irregu- 

 larly arranged; spinules on the scales of head arranged more regu- 

 larly in about 12 radiating lines. 



Tip of snout to origin of dorsal 4.30 in total length; first dorsal spine 

 small, second 1.80 in head, basal portion smooth, small spinides on 

 distal portion; rays of second dorsal anteriorly small, not connected 

 with one another by membrane, gradually growing longer to middle 

 of fin, then gradually becoming shorter, longest ray about 0.4 diameter 

 of eye; tip of snout to origin of anal 3.50 in total length; anal rays 

 much better developed than those of second dorsal; tip of snout to 

 origin of ventrals 4.40 in total length; outer ventral ray 1.77 in head, 

 filamentous at tip; pectoral 1.77.
