122 DEEP SEA FISHES. 
“Investigator” from the northern parts of the Indian Ocean, are noted by 
Alcock at depths of more than a hundred fathoms. In the present “ Alba- 
tross”’ collection there is a new species of Callionymus from between Malpelo 
Island and the Isthmus of Panama at a hundred and twelve to a hundred 
and twenty-seven fathoms. The slender claims of the group to a place on 
the lists of deep sea fishes rest entirely on the genera mentioned; the 
species mentioned show no special bathybial modifications.

Form of moderate elongation, depressed, tapering from the operculum 
to the snout and to the caudal; body cavity less than half of the length 
to the base of the caudal. Head one third of the length to the base of 
the tail, two thirds as wide as long, hardly two thirds as deep as wide, 
broad and slightly convex across the parietal region, narrow and grooved 
between the eyes, narrow and blunt on the snout, with a low arch from 
snout to nape. Snout as long as the eye, wider than deep, subangular 
forward, rounded at the end. Nostril porelike, nearer to the eye than to 
the end of the snout. Mouth small; maxillary extending little, if any, 
behind a vertical from the front edge of the orbit. Teeth small, in short 
villiform bands which are widest near the symphyses and narrow rapidly 
backward. Eyes large, very prominent, close together; orbit as long as 
the snout, less than one third of the length of the head. Process of the 
preoperculum stout, turned upward at the end, bearing a strong upward 
directed spine and a stronger one directed forward. Gill openings small, 
superior, directly forward of the upper edge of the pectoral base. Four 
gills; rakers five to six, short, clubshaped. Pseudobranchiz medium. 
Lateral line single; distinct, with very small, closely placed pores on the 
flanks and across the aural region at the nape; indistinct, and with scattered 
pores on the head. 
Dorsal originating opposite the middle of the space between the base of 
the pectoral and the gill opening, at one third of the distance from the 
snout to the base of the caudal, first ray longest. Second dorsal higher 
forward, pointed behind, hindmost rays longest, reaching the bases of the 
caudal rays. Anal fringed, origin below the third or the fourth ray of
