PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 421 
18. CORYPHAENOIDES ORTHOGRAMMUS (Smith and Radcliffe). 
Macrourus orthogrammus SmirH and Rapcuirre, Proce. U. S. Nat. Mus., 
vol. 43, 1912, p. 123, pl. 27 fig. 3. 
This species is a very distinct one, having no close allies. It differs 
generically from Lionurus parvipes and Matacocephalus, with which 
its describers compared it, in the number of branchiostegal rays, of 
which there are 6 instead of 7. ; 
C. orthogrammus is known only from the type-specimen dredged 
from 1,262 fathoms, by the Albatross, at station 5636 near Gomomo 
Island, in Pitt Passage, Dutch East Indies. 
The width over the pectoral bases is but half the greatest depth of 
the body. The length of the orbit is contained 4.2 times in the head; 
the width of the wide, flat interorbital space, 3.4 times. The promi- 
nent supranarial ridges are arched inward. The sides of the head 
are parallel, not diverging posteriorly; the distance between the 
lateral terminal tubercles is equal to the interorbital width. Length 
of the upper jaw, 3.8. The denticulate margin of the preopercle is 
produced backward in a wide curve, which nearly covers the posterior 
lobe of the interopercle. The preopercular ridge is sharply produced 
backward. 
The scales are in five series between the origin of the second dorsal 
and the lateral line series. 
The ventral fin is inserted directly below the origin of the first 
dorsal and the base of the pectoral, at a distance from the center of 
the anus equal to the interorbital width, and at a distance from the 
isthmus equal to the length of the snout. 
The lining of the buccal cavity is dusky; of the branchial cavity, 
bluish black; of the abdominal cavity, brownish black. 
Measurements in hundredths of length to anus (48 mm.)—Length 
of head, 74; length of orbit, 17; width of interorbital, 22; width of 
suborbital, 10; orbit to preopercle, 33; length of snout, 25; length 
of upper jaw, 24; length of barbel, 2.5; depth of body, 49; width of 
body, 26; length from anus to ventral, 22; from ventral to isthmus, 
26; length of first dorsal base, 19; length of outer ventral ray, 50. 
(orthogrammus, perhaps in reference to the strongly marked line 
formed by the suborbital ridge.) 
19. CORYPHAENOIDES CAMURUS (Smith and Radcliffe). 
Macrourus camurus SmitH and RapciiFFe, Proc. U. 8S. Nat. Mus., vol. 48, 1912, 
Deeley ake ite 2. = 
This remarkably peculiar species is known only from the small 
type, dredged at Albatross station 5428, off eastern Palawan, at a 
depth of 1,105 fathoms and at a bottom temperature of 49.7° F.
