124 DEEP SEA FISHES. 
of caudal; crown arched, interorbital space sharply convex, apparently 
without a crest, tentacles, or filaments. Snout somewhat pointed, as long 
as the eye. Hye large, three tenths of the head. Mouth small, maxillary 
not reaching to the middle of the eye. Teeth anterior, cusps acicular; a 
larger, hooked canine behind the series at each side on the lower jaws, and 
in front of this another smaller and more slender one; upper teeth similar 
to the lower ones, but with a single smaller canine at the end of the series 
near the angle of the mouth. 
Dorsals continuous; the contiguous ends marked by a notch; first spine 
above the upper angle of the gill opening, above the axil of the ventrals. 
First anal spine below the ninth spine of the dorsal. Pectorals broadly 
rounded. Externally the ventrals appear to have only three rays, but 
dissection uncovers a rudimentary fourth. Caudal subtruncate. Skin 
smooth; lateral line on the body indistinct. 
Color above the abdominal cavity very light brownish yellow. Whitish 
to translucent on the flanks and the sides of the head; belly silvery. A 
large spot of red on the middle of the pectorals; upper lip red; two or 
three narrow blotches of red across the nape, and a transverse streak of the 
same color interrupted in the middle at the bases of the caudal rays. There 
are groups of brown puncticulations on the caudal pedicel in front of the 
red streaks. Fins light, with a little more of brownish toward their bases. 
Total length thirteen sixteenths of an inch. 
Taken in the townet off the Cocos Islands. 
TRACHYPTERIDA — POMACENTRID A. 
Neither Trachypteride, Lophotidee, Fistulariidae, Centriscidae nor Poma- 
centride, of ¥arious groups not introduced here, are to be found in the 
material on which this report is made. The genera Trachypterus, Stylo- 
phorus, Regalecus, and Lophotes as noted in the “ Challenger” report by 
Giinther are given depths of three hundred to five hundred fathoms without 
definite depths for particular species. Vaillant reports Macrorhamphosus 
scolopax Linn., taken off the northwestern coast of Africa, from a hundred 
and twenty-eight fathoms, and a species of Aulostoma, obtained off the 
coasts of Morocco, from a depth of six hundred and thirty-five. Heliastes 
roseus Giint., secured in the neighborhood of the Ki Islands, is credited 
with a depth of a hundred and forty fathoms.
