PHILIPPINE MACROUROID FISHES — GILBERT AND HUBBS. 403 



half that of the eye to two-thirds that of the head (1.25 in eye in 

 type) ; it is probably a healed stub when extremely short. The 

 pseudobranchial filaments are covered by a membrane, which is rup- 

 tured in the type-specimen. 



The gill-rakers are slightly roughened on their inner edge; are 

 bluntly tipped, rather widely spaced, and are short, being about as 

 long as the least suborbital width in the adults, but relatively a little 

 longer in the young. Number of gill-rakers 6-J-23 and 6-|-24 on 

 the two sides of the type, varying from 5-f-20 to 6+24 in the para- 

 types; other gill-structures as in related species. The scapular for- 

 amen is in contact with both the hypercoracoid and the hypocoracoid. 



The scales in their finer structure are very similar to those of the 

 other species. Toward the margin of the scale in the type-specimen 

 there appears a break in the rings like the breaks which appeared 

 more strongly in G. denticulatus. There is also that approximation 

 of striae which, occurring near the center of the scale, may represent 

 a check in the first year's growth. This approximation of the rings 

 occurs in all of the species examined. 



There are constantly seven scales in a series between the origin of 

 the second dorsal fin and the lateral line scales. The scales on the 

 mandible are in two series except at the anterior end of the rami. 

 The lateral line, high on the trunk' runs below the middle of the 

 tail. 



The first spine of the dorsal fin is concealed ; the second is greatly 

 produced, but less so than in G. multifilis, G. longifilis, or G. mag- 

 nifilis; its length is a half greater than that of the head, or 0.85 of 

 the length to the anus in the type, varying in the paratypes from 

 shorter than the head to considerably less than twice the head, and 

 varies from half the length to anus to a little more than that length. 

 The length of the second pectoral ray varies greatly, from less than 

 three-fourths to one and a half times the length to anus. The length 

 of the outer ventral ray never approaches twice that of the head, 

 but is always longer than the head; it is four-fifths (0.65 to 0.93) as 

 great as the length to anus. The first dorsal, pectoral and ventral 

 fins begin on about the same vertical. The distance between the 

 anus and the base of the outer ventral ray is contained about 1.5 

 times in the head. 



Pyloric caeca (in several specimens), 35 to 52. 



The color was apparently dark brown, a little darker on the belly, 

 and blackish on the snout, mandible, and sides of the head. The sil- 

 very reflections on the abdominal region and on the sides of the head 

 are probably less marked than in the preceding species. The buccal, 

 branchial, and peritoneal cavities are wholly lined with black, being
