No. 2392. NEW DEEP-SEA FISHES FROM HAWAII— .JORDAN. 651 



out spine. Teeth very small, even, apparently in a narrow band 

 (characters of teeth, gill rakers, and branchiostegais, not to be 

 ascertained without dissection). Gill membranes free from the 

 isthmus, but broadly united across it, and covered with small rough 

 scales. 



Scales of body unique, each developed as a long thin vertical 

 strip, of the color and texture of the material of a wasps' nest; the 

 edges parallel, each scale many times as deep as long; with three 

 or four parallel vertical ridges roughened with small prickles, and 

 each with a vertical series of larger prickles turned backward, along 

 its base, apparently not on the scale itself, but on the basal skin. 

 Similar scales on cheeks, opercles, and gill membranes; scales on 

 caudal peduncle gradually assuming by degrees a normal form, 

 small, rounded, and rough at base, the edges entire. A very narrow 

 lateral line curved upward on anterior half of body, straight and 

 nearly horizontal behind; fins scaleless, mandible scaly; snout, 

 nostrils, and upper jaw with some naked skin. A row of stout, 

 hooked, immovable thorn-like spines along base of dorsal and anal, 

 these subequal in size. Dorsal fin with the spines rather low and 

 weak, the second a little elevated, about as long as eye (broken in 

 the type) ; soft rays low slowly rising posteriorly where the longest 

 is about 2\ in head. Anal with three stiff curved spines, the first 

 two serrated, the second nearly 4 in head. Soft anal longer than 

 soft dorsal, separated from the spinous part by a short notch 

 (whether actually connected or not can not be now determined), 

 the last rays about equal to the last of dorsal. Rays of pectoral 

 dorsal and anal not branched. 



Caudal peduncle rather slender, compressed, longer than deep, 

 its length two-thirds that of head, its least depth about one-third; 

 broadened at base of caudal fin, which is narrow, rounded, its middle 

 rays longest, a shade longer than head; pectoral short, rounded, 

 1\ in head; ventrals inserted just before them; longer than 

 pectoral 1§ in head: ventral spine and outer rays of caudal strongly 

 serrate, as is the first spine of the dorsal and the first two of the 

 anal. 



Shoulder girdle slender, apparently normal, so far as can be 

 ascertained without dissection. 



Color uniform slaty gray, the tip of caudal and edges of vertical 

 fins blackish. 



The type is in fair condition except for having been dried in 

 the sun. 



This extraordinary fish is plainly allied to the Zeidae, although 

 very properly placed in a different family, Gramrnicolepidae. The 

 only other species of this family known, Grammicolepis brachiusculus
