PHILIPPINE MACROUROID FISHES — GILBERT AND HTJBBS. 501 



The anus is located immediately before the origin of the anal fin : 

 its distance from the base of the outer ventral ray is less than the 

 distance between the ventral fin and the isthmus, and is equal to, 

 or less than, the length of the orbit, being contained 3.7 (3.4 to 4.65) 

 times in the length of the head; distance between ventral fin and 

 isthmus, 3.1 (2.7 to 4.0) ; distance between anus and isthmus, 1.85

(1.65 to 2.4). As in the foregoing species of the subgenus Oxyma- 

 crurus, the anus is preceded by a short naked area, which lies just 

 below the gland-like organ in the body wall. 



Pyloric caeca, 39 (in one paratype), shorter than the orbit. 



Scales large, in but 4^ (or 4) rows from the origin of the second 

 dorsal fin to but excluding the lateral line series. The numerous 

 carinae, bearing many comparatively weak spinules, are highly diag- 

 nostic of the species. There are from 6 to 11 carinae on the scales

of specimens more than 95 mm. long to anus, and from 5 to 8 in 

 smaller specimens. The short and slender spinules lack the promi- 

 nent ridges and concave surfaces as described for G. smithi; the 

 spinules, furthermore, are more numerous than in that species, there 

 being about 8 on each carina, as many as 6 in the specimen only 

 46.5 mm. long to the anus (7. is the largest number of spinules in 

 any series in the adult of G. smithi). The terminal rostral plates 

 are each armed by about four long rows of spinules, which become
