 the apex of th'i- V on niodian line I.etweeu nostrils; a narrow lian.l of spiiions si'ales snrronndini; 

 anterior segment of ,,rliit; |,reo|,ercular ansrle a little prodnced, its vrrti.-al mar-in ri.ncav.'; i,'ill- 

 niendjranes narrowly joined arross throat and largely free from isthnnis. 



Second dorsal spine with S strong serrations, evenly spaeed, mine of these <m the hasal fointh; 

 filanientons tip short, the entire spine contained 1.4 times in head; interspace, between dor.sals e.pial 

 to' base of the lirsf; .second d.n-sal very low; anal originating nnder third or fonrth ray of lirst dorsal, 

 its longest ravs ecpial to l<.ngth of sn.mt and eye; peebirals long and slen.ler, leacliing to ,,pposite 

 wventrenth anal rav. their length I.."! in that of head; tilament.ms ventral ray reaching base ..f twen- 

 tieth anal ray, its length eqnaling that of la-ad; distance from vent to axil ..f venlrals 0.7 its distance 



from front of anal. 



Scales small, verv decidnous, mostly lost in the type, 11 in a series from lateral line to base of 

 second dorsal spine; those <m back, under origin of sec.md dorsal, have each a strong nie.lian ridge 

 vvhieh Ijears 5 short strong spines directed very obli(iuely backward, and a pair of shorter lower ridge.s, 

 parallel with the lirst, and bearing fnmi 1 to H similar spines; cm breast, hea.l, and antedorsal region 

 the scales are smaller and bear usnally the median riilge only. 



Color, back and si.les grayish, checkered by narrow black lines margining the scales; sides 

 and lowerp'rtof head and abdomen jet-black; gill-m.-n,branes bhi.-kish on inner snrface as well as 



outer, but the lining membrane of month' an. 1 gill-cavity olherwi.se whitish; perit. nm dusky silvery; 



along the sides and tail about 12 narn.w black cross-lines, the posterior more distinct tlinn the anterior, 

 only^a few of them comi)lete; dor.sal uniformly dusky, anal translucent, with a wide Ijlack margin; 

 pectorals and ventrals, including the \ciitral lilament, blackish. 



Only the type known.

Head d(-pressed above ,.rbits, a l.nv convex curve thence to dorsal, the base of which .Iocs not 

 f,,rni a i,r..jection; contours of sn<.ut evenly and bluntly ronn.le.l; cheeks and suborbitals nearly ver- 

 tical, without projecting ridges or prominences; interorhital convex and very wide, .S.S times in length 

 of head; horizontal and vertical diameters of orbit equal, 1.4 in interorhital width, 5 in head; snout 

 projecting but little beyond mouth, its length contained 3.2o times in head; distance from premaxil- 

 laries to tip of snout 0.12 length of head; maxillary reaching a vertieal from middle of orbit, its length 

 2.4 in head; mandible well included ; premaxillary teeth in a moderate band; posterior teeth villiforni ; 

 outer teeth enlarged, formin- small canines, the enlarged teeth including some behind the outer series; 

 the premaxillary band narrows laterally, but contains always smaller teeth behind an outer series- 

 mandibular teeth uniform in size, intermediate in .size between inner and outer premaxillary teeth; 

 they form at symphvsis a very broad band which tapers rapi.lly toward sides; barbel .17 length of 

 head; nostrils small, the anterior round, with it.s posterior membranous margin elevated, the posterior 

 vertically slit-like; preoperc-ular angle greatly produced bai-kwai-d, the margin above angle deeply 

 indented: gill-membranes widely joined anteriorly, adnate to the isthmus, without free posterior edge; 

 braru-hiostegals H; outer Ijranc-hial slit very short, the arch almost wholly adnate; l.-ngtli of slit but 

 0.8 diameter of orbit; slit behind fourth areh slightly wider; pseudol)ranchia' jiresent, small. 



Second dorsal sjiine compressed, rather slen.ler and Hexible, its anterior margin furnished with a 

 few very tine serrulations; it is jiroduc-ed to a short filamentous tip, which reaches baseof twelfth ray of 

 second dorsal, and is more than 0.!» length of hea.l; first soft ray O.S lengtli of head; interspace lietween 

 dorsals slightly ex.-ee.ling in length base of first, an.l cntaine.l ::.4 times in head; origin of anal verti- 

 cally below beginning of last third of interspace betwi-en dorsals; all anal rays injured, the longest 

 present being .^2 the length of head, and nmc-b longer than niys of second dorsal; vent immediately in 

 front of anariin; outer ventral ray greatly produced, reaching base of nineteenth anal ray, 0.25 total 

 length; piM-toral rea.-liing to opposite twenty -second scale of lateral line; none of its rays produced, the 

 longest 1.7 in head.
