BOTllROCAROPSIS ELONGATA. 129 



one fifth of the total length, high .at the nape, nearly as wide as high, with 

 a very low arch from occiput to the preorbital section. Parietal region 

 broad, slightly convex transversely ; interorbital bones half as wide as 

 the eye ; a low median keel behind the orbits on the top. Bones of skull 

 thin, with large mucous cavities. Snout moderate, deep, blunt, one and 

 one third times the orbital length, more pointed than that of B. alalonga. 

 Mouth wide; cleft almost subtending the entire ej^e ; maxillary reaching 

 backward of a vertical from the hind edge of the oi'bit, where it is 

 expanded widely and sends down an angle behind tlie intermaxillary. 

 Lower jaw shorter, included by the upper. Teeth conical, small, in bands 

 on the jaws, on which the outer series are slightly larger, in two or more 

 series on vomer and palatines. Eyes large, one fifth as long as the head, 

 length one and one third times the space on the forehead between them. 

 Interorbital space three fourths of the length of the orbit, convex. Cheeks 

 and nape muscular, swollen ; face above the jaws or snout hardly inflated. 

 Operculum small, hinder angle with a membranous point. Dorsal and 

 anal fins deepest in the middle of their lengths; longest rays of the former 

 less than one third as long as the head, shortening to caudal and nape; 

 anal shorter. Dorsal origin above the axil of the pectoral ; origin of the 

 anal below the eighteenth ray of the dorsal. Pectorals narrow, three fifths 

 as long as the head, sharp pointed. No ventrals. Caudal short, two thirds 

 as long as the eye, tapering with dorsal and anal to a sharp point. Scales 

 small, absent from head and for a short space behind it ; those on the 

 fins smaller. Lateral line apparently absent. Massiveness of head and 

 shoulders, with rapidity of taper, give this species a short and stout appear- 

 ance. Seventeen inches in total length. 



Light greyish brown (? reddish in life), fins lighter, with darker edges, 

 head whitish (reddish).
