anus and the ventral fins is blackish, but the region anterior to the 
ventrals-is usually dark brown (or light brown). The usual round- 
ish spot above and behind the pectoral fin covers about seven oblique 
scale rows, and is ocellated with a lighter ring, which is preceded by 
an indistinctly darker squarish saddle just before the first dorsal fin, 
and followed by a similar saddle extending below the interdorsal 
space. Silvery reflections are seen on the sides of the head and body. 
The coloration of the head in general is light, becoming dark brown 
near the anterolateral angles of the snout, and blackish on the 
opercle. The buccal cavity is lined with purplish brown, without 
light margins about the gape; the branchial cavity is lined with 
brownish black, with a narrow light margin along the free edge of 
the opercular and branchiostegal membranes. The vertical fins are 
blackish, varying to light dusky; pectorals, hght dusky; ventrals 
blackish, with a white filament. In the young the first dorsal may 
be whitish proximally, but black on the tips of the spine and the 
front rays. The tail of the young is crossed by bars which are wider 
than the light interspaces between them.

1 A pseudocaudal developed. 
(macrolepis, in reference to the large scales characteristic of this 
species. ) 
32. COELORHYNCHUS CINGULATUS, new species. 
Type-specimen.—Cat. No. 78221, U.S.N.M., a male, 136 mm. long 
to the end of a broken pseudocaudal, 56.5 mm. to the anus (about 
0.5 mm. of tip of snout estimated as broken off). The type was 
dredged by the steamer Albatross at station 5317, in the China Sea 
near Formosa; depth, 230 fathoms; bottom temperature, 50.6° F.
