PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 515 
OXYGADUS, new subgenus. 
We unite into a subgenus certain species of Coelorhynchus 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, C. parallelus (Giinther), it includes 
C. kermadecus Jordan and Gilbert, C. spinifer, new species, C’. ara- 
trum Gilbert, C. doryssus Gilbert, C. occa (Goode and Bean), (. 
talismant (Collett), and probably additional species hitherto con- 
fused with C. parallelus. 'The group is almost surely a natural one.

439; Challenger Reports, vol. 22, 1887, p. 125, pl. 29, figs. A’ and AA’’. 
[figs. A, A’’, a’’, and a’’’, probably represent a distinct species called C. 
kermadecus by Jordan and Gilbert (Bull. U. S. Fish Comm., 1902 (1904), 
p. 619). The specimens from New Zealand perhaps represent a third 
species. ].—Japan; Kermadec Islands; New Zealand.

a distinct species, having 7 or 9, usually 9, instead of 3 to 5 rows of 
spinules on the scales).—off southwestern Africa. 
? Coelorhynchus parallelus WerBER, Fische der Siboga-Expedition, 1913, p. 
163, pl. 4, fig. 3—Hast Indies. 
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. 8.2—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 with 
C. parallelus, we do not feel justified in naming or defining them on 
the basis of published descriptions.
