Family CHAMPSODONTIDiE. 
Champsodon fimbriatus, new species. Plate 88. 
Type, a female 80 mm. long, from station 4101, Pailolo Channel, depth 122 to 143 fathoms; type, 
No. 51629, U. S. Nat. Mus. 
Differing from Champsodon vorax Gunther (Shore Fishes, Challenger, 43, 52, pi. 23, fig. A) in the 
much deeper body and the shorter spinous dorsal. 
Head 29 hundredths of total length, without caudal; depth 23 (19 in vorax)-, least depth of caudal 
peduncle5.5; length of maxillary 19; snout 9; eye 5.5; interorbital width 3.5; distance from tip of snout 
to origin of dorsal 37 ; distance between origins of first and second dorsals 12. (In C. vorax, distance from 
tip of snout to origin of spinous dorsal 31 hundredths of length; distance between origins of dorsals 
16). D. iv-19; A. 17; P. 14; V. i, 5. 
Top of head flat between the ridges, which are roughened and entirely similar to those in vorax. 
Mandible projecting much at tip, but laterally included; premaxillaries with a double notch anteriorly 
to receive mandibular tip; a short filament on upper part of eye-ball, and a smaller broader process 
behind it, this process lacking in vorax; process on anterior margin of preorbital bearing 2 more or less 
diverging sharp spines, not 3 as in vorax. Spine at angle of preopercle similar, long, compressed at 
base and curved; two shorter spines directed downward and forward on horizontal limb, and some 
irregular serrulations on vertical limb of preopercle; opercle without spine, very thin and flexible, 
striate, with a wide membranous margin which is much more coarsely fringed than in vorax; teeth 
similar, but more slender and less curved; but 2 or 3 small teeth directed backward on each side 
of head of vomer, these working directly against 2 small patches of similar teeth on the basibranchials 
of the fourth arch; no tongue present; a wide slit behind the fourth gill-arch; pseudobranchise present; 
gill-rakers 2 + 12 on first arch; gill-membranes not united; anterior end of gill-slits vertically below 
nostrils; branchiostegals 7. 
First dorsal shorter than in C. vorax and more posteriorly inserted; also less widely separated from 
soft dorsal; spines usually 4 in number (4 in 10 specimens, 5 in 5 specimens counted), while in vorax 
they are usually 5, rarely 6. Pectorals very slender and short, with very fine rays, their length 
equaling that of snout and half eye; ventrals with the fourth ray longest, reaching anus; caudal widely 
forked; all the dorsal rays save the first are once forked near the tip, the branches not divergent, the 
last ray cleft to base; anal rays similar to those of dorsal. 
Scales a little coarser than in vorax; each scale subcircular, attached centrally, elevated above the 
general surface, the margins free; posterior margin of each side with from 3 to 6 strong spines, of which 
the central ones are the longest; scales closely adherent, and completely investing head and body; 
the breast and belly, the opercle, s, except only the thin membranous margin, the cheeks, snout and 
top of head, the maxillary, premaxillary and mandible and the gular membrane, all closely covered; 
two lateral lines present on side, a line on each side of occiput running backward along base of spinous 
dorsal, numerous lines on head, and many cross lines above the upper lateral line and below the 
lower. Sensory organs are lodged in small freely-projecting papillae, which project among the scales. 
Color dusky brownish on back with 3 faint broad dark cross-bars; sides and below silvery, the 
sides speckled with brownish; fins all whitish, Unmarked. 
Many specimens were obtained at station 4101, but the species was not obtained elsewhere. In 15 
specimens examined, the dorsal and anal fin counts are as follows: Dorsal iv-18, anal 16, 1 specimen; 
iv-18, anal 17, 1 specimen; iv-19, anal 17, 3 specimens; iv-19, anal 18, 1 specimen; iv-20, anal 17, 2 
specimens; iv-20, anal 18, 2 specimens; v-19, anal 16, 1 specimen; v-19, anal 17, 1 specimen; v-20, 
anal 18, 3 specimens. 
Family CALLIONYMIDvE. 
Callionymus cseruleonotatus, new species. Plate 89. 
Type, 86 mm. long, 49 mm. to base of caudal, from station 4066, off east coast of Maui, depth 49 
to 176 fathoms; type, No. 51603, U. S. Nat. Mus. 
Length of head (measured to opercular margin) 31 hundredths of total length without caudal; 
depth 12; width at base of pectorals 17; length of snout 9; diameter of eye 9; length of maxillary 10; 
distance between branchial pores 9; distance from tip of snout to first dorsal -spine 28; length of first
