 Snout very blunt; rounded when \'iewed fi-om al)ove; truncate when 

 seen from the side. 



Eyes high in head; directed obliquely upward; interorbital space 

 very narrow, flaws subequal, the lower slightly included. Mouth 

 rather small; the cleft somewhat oblique. Lips larg(>. Maxillary, 

 except the tip of the distal end, concealed; extending to a vertical 

 through a point a little behind anterior edge of orbit. Space between 

 or))it and maxillary about equal to longitudinal diameter of eye. 

 Tongue Inroad; rounded anteriorly; its free edge narrow. Teeth sim- 

 ple; in narrow l)ands on jaws; outer ones largest, slender, sharp, 

 slightly curved; the ones on sides of lower jaw enlarged, though not 

 notal)ly so, there l)eing no strong canines. Gill-opening not extending 

 far forward; the width of isthmus about equal to length of maxillary. 

 Inner edge of shoulder girdle projecting as a sharp ridge, without 

 papilla? or other dermal modifications. Gill-rakers on first arch, 2 + T 

 or 8; short and pointed. Anterior nostril with a high rim. No

 immediately anterior to pectorals, the breast in front of ventrals, and a 

 narrow space extending l)ackward ncnrly to vent naked. 



Dorsal tins separate from each other and from the caudal; second spine 

 highest; the others successively shorter, when depressed just reaching 

 origin of soft dorsal; dorsal rays, when depressed, falling far short of 

 base of caudal. Anal inserted directlv below base of third dorsal ray; 

 the rays somewhat longer posteriorly, when depressed extending as far 

 back as the dorsal. Pectorals pointed, their tips reaching a vertical 

 through insertion of soft dorsal; the upper ravs with appendages. 

 Ventrals long, not extending so far posteriorly as pectorals; free from 

 body except at ])ase.

 dai'ker spots and reticulations; sides with six or seven poorly defined 

 lateral spots, the last and most conspicuous one at l)ase of (-ludal fin.
