 Plate 30, fig. 1. 



Dorsal ii,9-88; anal 88; ventrals 7; pectorals 18. 



Head 3.95 in total length, short, broad, greatest breadth and 

 greatest depth being about equal; ridges on occiput distinct, arranged 

 as in commutahilis ; suborbital ridge salient, ending abrubtlr in front 

 of angle of preopercle; body rounded, greatest depth 7.40 in total 

 length; vent less than diameter of pupil in front of origin of anal; 

 tail compressed, tapering; eve subelliptical, horizontal diameter 3.50 

 in head, about 0.75 length of snout, 1.21 in postorbital; vertical 

 diameter about 0.75 horizontal diameter; interorbital 4.45 in head, 

 1.54 in postorbital, broad, slightly concave; snout 2.62, short, broad, 

 a strong median ridge on doKal surface; laterally convex, rather 

 blunt at tip; wddth of snout at anterior margin of eye equal to its 

 length, its width midway between tip and eye about 0.7 its length;

postorbital portion of head 1.09 in snout; nostrils as in commutabuis; 

 mouth large, its anterior margin in vertical from posterior margin of 

 anterior nostril, as in the type of commutabUis, its distance from tip 

 of snout 2.97 in head, 1.03 in postorbital; mandibular barbel about 

 0.3 horizontal diameter of eye; teeth incurved, cardiform; scales large, 

 imbricate, quite deciduous, 5 in each series from origin of dorsal and 

 from last dorsal ray to and including lateral line; scales on body 

 armed vriih. from 5 to 7 well-developed radiating ridges; the median 

 ridge in many of the scales somewhat stronger than the others; scales 

 of head and body similar to those found on commutahUis except that 

 the ridges are more pronounced, especially those on imder side of head. 

 First dorsal spine small, second longest, nearly as long as snout 

 plus eye; interdorsal 0.22 length of head; second dorsal low; anal rays 

 better developed than the corresponding rays of second dorsal, 

 longest ray about 0.75 horizontal diameter of eye; ventrals small,
