PHILIPPINE MACROUROID FISHES — GILBERT AND HUBBS. 485 



1 Type. 



Type-specimen. — 387 mm. in total length; 150 mm. to anus; 

 dredged at Albatross station 5585. 



Fin-rays 1 — first dorsal, II, 9; pectorals, 18 (to 16) ; ventrals, 7. 



The general form of the body is correctly indicated in the two type 

 figures ; the greatest depth of the body, at the posterior end of head, 

 is contained 1.9 (to 2.1) times in the length of head to end of opercu- 

 lar membrane. The greatest width of the body is contained 2.5 

 (to 3.0) times in the head; the greatest width of the head is equal to 

 its depth through the hind margin of the eye. Preocular length of 

 snout, 2.7 (2.5 to 2.9) ; preoral length, 3.05 (2.9 to 3.3) ; width of 

 snout across its base, 2.7 (to 2.5) ; width of snout at end of ethmoid 

 region of the infraorbital ridge, into the distance from that point to 

 the tip of snout, 0.75 (to 0.8). The occipital ridges diverge rather 

 widely posteriorly ; the least distance between them is contained 1.7 

 (to 2.0) times in interorbital. Length of the orbit : 3.4 (3.35 to 3.6) in 

 head; 1.25 (1.2 to 1.4) in snout; 1.2 (to 1.25) in postorbital. Least 

 interorbital width, 1.6 (1.5 to 1.7) in postorbital; least suborbital 

 width, 2.5 (2.4 to 3.0). Length of upper jaw into head, 3.85 (3.8 to 

 4.1) ; the upper jaw extends from below the hind margin of the an- 

 terior nostril backward to a vertical passing across the eye between 

 its hind margin and the pupil. Branchiostegal rays, 6; the gill- 

 membranes form a free fold across the isthmus. The free length of 

 the barbel enters 4.9 (4.2 to 5.2) times into the postorbital length of 

 the head. The lower subopercular angle is produced backward as a 

 long narrow flap, which is curved slightly downward distally. 



Distance from center of anus to base of outer ventral ray, 2.15 (to 

 2.9) in head; distance from ventral fin to isthmus, 3.2 (to 3.6) ; dis- 

 tance from anus to isthmus, 1.3 (to 1.6). The anus is immediately 

 preceded by a naked space about as long as the peritroct; above it, 

 between the muscles of the body wall, there lies a flattened gland-like 

 body which probably represents the structure described in some de- 

 tail in other species; in color this organ is black below, and dusky 

 above. 



Thirty-two pyloric caeca about as long as the orbit were counted 

 in a paratype. 



1 Counted in all eisht specimens.
