Head 3: eye 2j; snout li in eye, or ^ in interorbital width. D.9; A. 30; 

 V. 6; scales 35. Head and body compressed; the body covered with 

 large, cycloid, deciduous scales. Height of body at vent less than length 

 of head, equal to distance from posterior margin of orbit to end of lower 

 jaw. Eye slightly greater than distance from its anterior margin to tip 

 of lower jaw. Mouth subvertical; length of upper jaw slightly exceed- 

 ing diameter of orbit. Teeth iu villiform bands on jaws, palatines, and 

 vomer. Dorsal fin placed at a distance from tip of snout equal to twice 

 height of body ; its first ray inserted in vertical from base of seventh 

 anal ray. Pectoral slender, its upper rays the longest, extending consid- 

 erably beyond the origin of the anal. Ventrals small, fan-shaped, inserted 

 almost under the posterior margin of the orbit. Color yellowish silvery. 

 One specimen, 13 inches in length, obtained by the Blake at station 37, 

 off Neris, at a depth of 365 fathoms. (Goode & Bean.) {argenteus,

Family CXII. STEPHANOBERYCIDtE. 



Body oblong, compressed, with scales of peculiar form, circular, having 

 in the center of each one or two erect, conspicuous lines, and in arrange- 

 ment scarcely imbricated. Head large, thick, oblong, cavernous, with 

 short convex snout, and with thin osseous ridges, especially an inner 

 U-shaped one on the crown, whose limbs diverge on each side of the 

 nape ; also an outer sigmoid ridge on each side above the eyes, continuous 

 with a similar ridge projecting from the nasal bone, the inner and outer 

 ridges being connected by a cross ridge opposite the anterior margin of 

 the orbit. Mouth very wide and somewhat oblique. Lower jaw slender 

 and slightly projecting. Maxillaries large; premaxillaries protractile; 

 suborbitals narrow. Teeth small, in a single band on the intermaxilla- 

 ries and dentaries; palatine toothless. Bones of the head usually ser- 

 rated. Braucbiostegals 7 or 8 ; gill membranes separate, 3: gills 4, a
