inner rays much darker; upper pectoral ray blackish, rest of fm 

 dusky white; underside of head cream white; underside of opercle 

 blackish, the dark coloration showing through; lining of mouth 

 whitish anteriorly becoming dusky posteriorly; peritoneum silvery 

 black; no black spot above and behind pectoral. 



Type.— C&t. No. 72947, U.S.N.M., 20.5 cm. in length, taken with 

 a beam trawl at station 5418 (lat. 10° 08' 50" N.; long. 123° 52' 30" 

 E.), between Cebu and Bohol, at a depth of 159 fathoms, on a bottom 

 of gray mud and sand. 



This species is very close to C. gladius of GUbert and Cramer, from 

 the Hawaiian Islands, but differs from the descriptions of that species 

 in having fewer r&js in the pectoral and the first dorsal (all of the 

 specimens except the type have first dorsal ii,7), the filamentous 

 ventral ray reaching base of anal, interdorsal space about 0.5 orbit, 

 the anterior rays of the second dorsal relatively shorter, the ridges 

 on occiput more pronounced, in the absence of a large black spot on 

 side above pectoral, and the anterior anal ra^^s blackish instead of 

 white.

 Plate 30, fig. 3. 



First dorsal ii,9; ventrals 7; pectorals 16. 



Head 4.29 in total length, short, occipital ridges low, suborbital 

 ridge salient, ending abruptly in front of angle of preopercle; angle 

 of preopercle projecting, free margin slightly concave; body com- 

 pressed, greatest depth 6.72 in total length; vent 0.5 diameter of eye 

 in advance of the anal; tail compressed, rather deep anteriorly, 

 tapering posteriorly; eye large, subelliptical, horizontal diameter 3.31 

 in head, vertical diameter 1.44 in horizontal diameter; interorbital 

 4.77 in head, broad, flat, equal to vertical diameter of eye; snout 

 2.74, pointed, its dorsal outline slightly concave; laterally slightly 

 convex; mouth of moderate size, its distance from tip of snout 3 in 

 head; mandibular barbel rather stout, about half horizontal diameter 

 of eye; teeth slender, in a narrow cardiform band; scales regular, 6 

 in each series from origin of dorsal and last dorsal ray to and including 

 lateral line; each scale armed with about 7 to 9 low, nearly parallel 

 ridges, each ridge composed of long, slender recumbent spinules; 

 underside of head naked ; a narrow scaleless fossa extending forward 

 from vent along median line of belly to between base of ventrals. 



First dorsal spine small; second spine 1.21 in head (frequently 

 longer than head in smaller examples) ; interdorsal space about 0.3 

 of head; 8 series of scales crossing back between dorsal fins; second 

 dorsal low; origin of anal slightly in advance of vertical from origin 

 of second dorsal, its rays much longer than those of second dorsal; 

 ventrals widely separated, outer ray filamentous, 1.80 in head, its
