236 MEMOIRS OF THE CARNEGIE MUSEUM. 
edge of orbit, and ending shortly before the premaxillaries; lower edge of snout not as 
deep, but longer; siphonate part of snout noticeably deeper than the diameter of 
eye; upper edge of snout serrate anteriorly and posteriorly (contrasting with S. cy- 
anopterus) (Pl. XLI, fig. 1), the supra-orbital ridges, which fuse to form dorsal edge 
of snout, likewise serrated; upper and posterior edges of orbit very coarsely and 
noticeably serrate, or roughened. 
Distance from anterior border of eye to first dorsal spine greater than length 
of snout; height of dorsal spine 3.66 in body-length; tip of spinous dorsal extending 
to centre of base of second dorsal; distance between dorsal insertions 4.33 in body- 
length; height of second dorsal equal to diameter of eye; caudal peduncle from last 
anal ray to middle caudal rays short, 4.75 in head, length of caudal rays slightly 
greater than that of head; anal similar to soft dorsal; ventrals not adnate to belly, 
reaching middle of anal base. 
Color somewhat similar to that of S. cyanopterus; body with small brown spots; 
pectorals with somewhat larger ones; caudal with numerous elongate, irregular, 
large spots, the biggest half diameter of eye in length; dorsal with two elongate black 
spots on membranes between first three rays at mid-height, remainder of fin spotted, 
as is caudal. 
The measurements in hundredths of body-length of the type of Solenostomus 
pegnius are as follows:—Head, .45; snout, .30; eye, .05; maxillary, .06; body-depth at 
base of ventrals, .22; length of caudal peduncle from last anal to middle caudal rays, 
.095; depth of snout at middle, .10; height of first dorsal, .26; of second, .05; length 
of ventral fin, .26; of caudal, .48; distance between tip of snout and first dorsal, 
.62; between eye and first dorsal, .28; between insertion of dorsal fins, .22. Those 
of S. cyanopterus (Bleeker), in so far as they differ, are: depth at ventral bases, 
19; length of caudal peduncle, .08; depth of snout, .06; length of ventral, .33; of 
caudal, .34; distance eye to first dorsal, .25; between dorsal insertions, .26. 
This species differs from the Japanese specimen of Solenostomus cyanopterus 
(Bleeker) cited by Jordan and Snyder in the much deeper snout; form of the dorsal 
edge of the snout; the serrated ridges of head; the shorter snout as compared to the 
distance from the first dorsal spine to the anterior border of the eye; longer caudal; 
slightly greater depth; and shorter ventral. It is probable that the depth of the 
snout is not a sexual mark, as the male described by Tanaka as S. leptosomus has 
the slenderest snout of any as yet described, save that of the female of S. paradoxus. 
(Plate XLI, fig. 2). Franz has recently declared the two latter species synonymous, 
comparing his own specimen from Dzushi. This is not impossible. The position 
of the dorsal bases, and their ray-length may be sexual marks, as they must be, if
