PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 497 
in head—second dorsal spine, 2.6 (2.63 to 2.7); pectoral fin, 2.75 
(2.45 to 2.95), not notably shorter in large specimens; outer ventral 
ray, 2.65 (2.4 to 3.35), varying without apparent relation to the 
length of the fish; second ventral ray, 5.25 (4.4 to 5.3). 
Color, brown, usually darker than in C. commutabilis,; it is darker 
above than below; the belly is sometimes dark; opercle with a dark 
blotch. The young have darker bars on the tail, the first being 
located below the front of second dorsal, the second being separated 
from the first by an interspace about as long as the orbit; these mark- 
ings are very faint in larger specimens. The fins are all dark. The 
lining of the buccal cavity is bluish black; that of the branchial cav- 
ity, brownish black, with an abrupt whitish margin on the opercular 
and branchiostegal membranes; the parietal peritoneum is dark 
purplish. 
C. smithi is closely related to C. flabellispinis (Alcock),1 known 
from a specimen dredged by the /nvestigator at a depth of 719 
fathoms in the Arabian Sea. Certain differences, however, make 
the separation of the two imperative, as may be seen from the fol- 
lowing table:

We are far less certain as to Brauer’s? Macrurus (Coelorhynchus) 
flabellispinis. Most of his measurements and counts agree with those 
of CO. smithi, and it is not unlikely that his specimens from the west 
coast of Sumatra are referable to that species. But Brauer has 
failed, as in other cases, to designate the locality from which his 
described and mgasured specimens came. He had other specimens 
from southern and northeastern Africa. 
The relationships of C’. smithi with C. commutabilis are less in- 
timate. C. smithé has constantly larger scales; several carinae instead 
of a median keel on the scales of occipital ridges; browner and
