depression, its front profile nearly evenly semicircular, surface 

 generally convex, and length from middle of front snout ex- 

 tremity to eye about 3/5 its width. Eye a little ellipsoid, rather 

 high, and center falls about first third in head. Mouth small, 

 transversely crescentic, opens down and forward. Maxillary 

 small, reaches back trifle beyond front pupil edge though not 

 quite to eye center. Lips rather thick and fleshy, moderately 

 broad, with small papillae and obsolete plications. Jaw edges 

 obtuse, broad. ^Mandible shallow in front, rami well elevated 

 inside mouth. Tongue adnate, thick, fleshy, depressed. Nostrils 

 together, close before and about opposite eye center, anterior 

 large pore and posterior larger and with slight cutaneous flap in 

 front. Interorbital broad, rather unevenly convex, depressed in 

 front. Cranial bones somewhat cavernous. First suborbital 

 nearly of equilateral triangular form, length i 14 in eye. Sec- 

 ond suborbital much smaller and narrower, and third equally 

 narrow, though its length nearly equals eye. Last also with 

 very obsolete striae. Opercle and subopercle strongly striate, 

 former with width about half its length. 



Gill-opening forward about last fourth in head length. Gill- 

 rakers about 30+ 17. slender, i 4 '5 in eye. Filaments i 1/2 

 in eye. PseudobranchicT obsolete, less than filaments. Branch- 

 iostegals 3, robust, median a little more enlarged or bulky than 

 others. Isthmus width i i/io in eye. 



Scales large, moderately imbricated, of mostly uniform size, 

 disposed in series parallel with 1. 1., and each with manv radiat- 

 ing striae. Scales on breast but little smaller than others, though 

 those along bases of dorsal and anal smallest. Scales on base 

 of caudal rather small. Axillary ventral scaly flap scarcely de- 

 veloped. L. 1. complete, median along side, inclined little be- 

 low middle of caudal peduncle side. Tubes simple, extend 

 horizontallv to hind scale edges. No tubercles.
