hind border of the orbit, more than half as long as the head, very broad 
toward the end, forming about three fifths of the upper border of the mouth, 
rounded on the hind margin; intermaxillary with edge directed out and 
forward. Teeth small but rather strong, subconical, hooked, uniserial, on 
premaxille, maxille, dentaries, and palatines; one to three fang-like teeth 
at each side of the vomer. Symphyseal angle and that below the angular 
not very prominent; angle at the opercular hinge more prominent than 
that behind the orbit; angles in front of the eyes, or those forward of the 
nostrils low. Gills four; lamella short, narrow; rakers five plus sixteen, 
slender, sharp pointed, longest three fourths as long as the eye; membranes 
not united, free from the isthmus; openings very wide; pseudobranchiz 
small. Opercles membranous and thin toward the margins. 
Dorsal origin distant from the end of the snout one and two thirds times 
the length of the head, above the middle of the base of the ventral. Anal 
origin below the hind end of the base of the dorsal. Vent little backward 
of a vertical from the middle of the dorsal’s base. Ventrals moderate, 
reaching the anal. Pectorals small, low on the side of the body, reaching 
halfway to the ventrals. Caudal pedicel rather slender; caudal fin deeply 
notched. 
Surface and interior linings black. 
The specimen described has a length cf seven and one half inches. 
This species is readily separated from B. alvifrons by a smaller eye, a 
longer snout, a wider and longer maxillary, and by the fins and the scales.
