PHILIPPINE MACROUROID FISHES — GILBERT AND HUBBS. 515 

 Oxygadus, new subgenus. 



We unite into a subgenus certain species of C oclorhynchus which 

 are distinguished by the spination of their scales: there is a very 

 strong median spinous keel, with smaller lateral spinules, usually 

 not set on keels, but arranged in series parallel with the median keel. 

 In addition to the type-species, G. parallelus (Gunther), it includes 

 G. kermadecus Jordan and Gilbert, G. spinifer, new species, C. ara- 

 trum Gilbert, G. doryssus Gilbert, G. occa (Goode and Bean), G. 

 lalismani (Collett), and probably additional species hitherto con- 

 fused with C. parallelus. The group is almost surely a natural one.

[figs. A, A", a", and a"', probably represent a distinct species called C. 



kermadecus by Jordan and Gilbert (Bull. U. S. Pish Comm., 1902 (1904), 



p. 619). The specimens from New Zealand perhaps represent a third 



species.]. — Japan; Kermadec Islands; New Zealand.

spinules on the scales). — off southwestern Africa.

We refer to C. parallelus three small specimens from Albatross 

 station 5445, off the east coast of Luzon (383 fathoms; bottom tem- 

 perature, 44.3° F.). The scutes along the ridges of the head bear 

 a strong keel armed by several spinules of subequal strength. 

 Scales mostly lost; probably originally present on under surface of 

 head; 5 scales in a series above lateral line (to origin of second 

 dorsal). 



The measurements given by Weber indicate that his specimens have 

 the snout shorter than in our Japanese material. Concerning the 

 spination of the scales, Dr. Weber writes : " A specimen from station 

 52 of 220 mm. length shows about the following arrangement of 

 spinules: 2. 3. 4. 3. 2=14. A specimen from same station of 125 mm. 

 length shows on well-developed scales the arrangement: 2. 2. 2=6." 



Although it is evident that several species have been confused witli 

 C. parallelus, we do not feel justified in naming or defining them on 

 the basis of published descriptions.
