29. COELORHYNCHUS DORSALIS, new species. 
Type-specimen.—Cat. No. 78219, U.S.N.M.; a male, 200 mm. 
long (extreme tip of tail broken off), 59 mm. to anus, dredged 
by the steamer Albatross at station 5329, in 212 fathoms, off north- 
ern Luzon, where the bottom temperature was recorded at 51.4° F. 
A single paratype, 155 mm. long to the end of its pseudocaudal, 
about 47 mm. to anus, was taken near the type-locality, at station 
5326; depth, 230 fathoms; bottom temperature, 55.4° F. 
This species is the only one of the C. notatus group known froin 
off northern Luzon, and was not taken off southern Luzon, where 
C. velifer and macrolepis were dredged in abundance. 
Fin-rays—first dorsal, II, 8; pectorals, 17—17 (17—16 in para- 
type) ; ventrals, 7—Y. 
In its form this species is somewhat more slender than usual, its 
greatest depth being contained 1.95 times in the head (1.88 times in 
the paratype) ; width of body across pectoral bases, 2.75 (2.6) times; 
- at a point twice the length of the head behind the rostral tip the 
width of the body is just one-third of the depth. The dorsal contour 
of the snout is somewhat concave; that of the postrostral portion of 
the head is nearly straight, not being elevated at the occiput. The 
snout is long and diagnostically broad anteriorly, being especially 
wide between the comparatively prominent anterolateral angles, 
where the width is a little greater than either the orbital length or 
the length anterior to the angle on either side. The preocular length 
of the snout is contained 2.37 times in the head; preoral length, 2.7; 
width opposite front of orbits, 2.9 (2.8). The subopercle is produced 
backward and downward, from its lower angle, as a pointed flap. 
Length of orbit, 3.6 in head -(3.7 in paratype) ; 1.1 (1.15) in postor- 
bital; 1.5 (1.6) in snout. Least interorbital width, 1.7 (1.6) in postor- 
bital; least suborbital width, 2.6 (2.7). The upper jaw, contained
