PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 481 



A single paratype was obtained: length, 148 mm. to end of in- 

 jured pseudocaudal, 60 mm. to anus; Albatross station, 5325; lo- 

 cality, China Sea off northern Luzon; depth, 224 fathoms; bottom 

 temperature, 53.2° F; sex, female, with unripe ova in an elongate 

 ovary. 



Fin-rays — first dorsal, II, 8 (II, 9 in paratype) ; pectorals, 17 

 (18) ; ventrals, 7. 



The dorsal and ventral contours of the slender body are long, even 

 curves; the greatest depth is contained 2.2 times in length of head; 

 the greatest width across pectoral bases is about equal to the depth 

 below origin of lateral line, and is contained 2.8 times in length 

 of head. The dorsal contour of the head above and behind the 

 orbit is gently convex, while that of the snout is concave. The sides

of the head are straight medially along the preorbital and sub- 

 orbital portions of the infraorbital ridge, but the contour of the 

 ethmoid portion of the ridge is doubly curved, being convex 

 posteriorly, and concave anteriorly just behind the sharp, long, 

 and slender terminal spine; the length of the dorsoterminal plate is 

 contained 2.3 times in the postorbital (in paratype). The width 

 of snout at front of orbits is equal to the length of the ethmoid 

 region of the infraorbital ridge, and is contained 2.7 (2.85) times 

 in the head. Preocular length of snout, 2.2 in head ; preoral length, 

 2.4 (2.3). The occipital ridges are subparallel anteriorly, but di- 

 vergent posteriorly; the least distance between them is contained 

 1.3 (1.4) times in the distance between their terminations, and is 

 equal to the least suborbital width, each being contained 1.6 to 1.7 

 times in the interorbital. The postorbital ridge is curved slightly 

 upward anteriorly, slightly downward posteriorly. The lower sub- 

 opercular angle is produced downward and backward into a long, 

 blunt flap, in contrast with the more slender, pointed flap of the
