PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 407 



species of the genus, thus rendering the appearance of the fish most 

 similar to that typical of Bathygadus, in which genus these canals 

 are usually enlarged. The outlines of the body are less curved than 

 in G. colletti, denticulatus, or magniftlis, and the depth is less, not 

 being equal to the length of the head to the angle of the preopercular 

 ridge. Length of orbit, 1.2 in snout, 4.2 or 4.3 in head. The inter- 

 orbital is almost as wide as the eye, and is over twice the least width 

 of the bony suborbital; length of upper jaw, 1.6 to 1.7 in head, 

 extending well beyond orbit ; the teeth are coarser than in the other 

 Philippine species and are confined to very narrow bands, the greatest 

 width of the premaxillary series being contained from 3.3 to 3.8 

 times in the least suborbital width. Gill-rakers long, sharp, crowded, 

 strongly compressed, and rough on their inner edge, 6+26 on 

 the outer arch. The scapular foramen lies in the suture between 

 the hypercoracoid and the hypocoracoid. Small pseudobranchiae are 

 developed. 



Six scales, exclusive of the lateral line scale, in a series between 

 lateral line and origin of second dorsal. In their finer structure the 

 scales seem to offer good specific characters. In G. colletti, G. denti- 

 culatus, and G. magnifies the rings from the first, second, or third, 

 extend forward on the scale to meet their fellow at an acute angle. 

 The " circuli " thus soon become perpendicular to the basal margin 

 of the scale. In G. introniger and in G. multifilhs the first four rings 

 are subcircular, and even after these, the " circuli " do not run so far 

 from the circular course as do those of the other three species. In 

 all of these five species the circuli are first well spaced, but soon be- 

 come more closely approximated, the number of striae out to the 

 end of this crowded area being 6 to 10. In the true G. longifllis 

 this area of approximated circuli, very decidedly shown, occurs at 

 the very center of the scale, and includes the first five circuli (de- 

 termined in one of the type-lot). In longifllis the "circuli," even 

 more than in G. multifilis, retain their circular character. However, 

 the general character of the scales is the same in all the species. The 

 " circuli " posteriorly are nearly concentric, while anteriorly they 

 are more or less nearly perpendicular to the scale margin. They are 

 finely denticulate, and are connected by numerous cross ridges. 



On the trunk the lateral line runs above the middle of the sides, 

 but descends on the tail to a position below the middle of the depth. 



The fin filaments are very long, the second dorsal spine and the 

 outer ventral ray being each twice as long as the head. 



Pyloric caeca in a Philippine specimen, 12 ; in the Japanese speci- 

 men referred to G. multifilis, 16. Brauer counted 15 and 22 in two 

 specimens, Alcock counted 20 in one of the Indian specimens.
