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 magnifilis, 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. magnéfilis 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. multifilis 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. longifilis 
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 Jongifilis the “ circuli,” even 
more than in G@. muiltifilis, 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. 
Whether Brauer’s and Alcock’s specimens are referable to G. multi-
