38 MEMOIRS OF THE CARNEGIE MUSEUM 
Body with very small scales; the throat, breast, a considerable area including 
base and axil of pectoral, and a narrow space extending back from occiput to base of 
dorsal naked; minute scales on upper edge of opercle and preopercle and also 
on cheek immediately below eye. Lateral line with a long curve above pectoral, the 
curved portion equal to half the length of lateral line; 14 or 15 small plates on 
tail, each with a low keel and a posterior spine. Base of caudal with 5 pronounced 
lateral keels, the pair on each of the median one oblique and convergent pos- 
teriorly. 
First dorsal with 7 spines, the posterior two separate and very small; highest 
spine 24 in head. Anterior part of soft dorsal filamentous, the tip when depressed 
extending beyond base of caudal; median rays also filamentous, the filamentous 
extending above edge of fin a little over half their length. Anterior rays of anal 
closely united to form a filament which extends to base of caudal when depressed, 
the succeeding rays low. Both soft dorsal and anal with a high sheath of very 
small, thin scales. Ventrals 24 in head. Pectorals falcate, 2¢ in the length. Caudal 
lobes equal, 375 in the length. 
Color in spirits silvery ; median dorsal region dusky, opercle dusky above, axil 
of pectoral black ; filaments of dorsal and anal black, caudal dusky on edges and 
on posterior border, ventrals tipped with blackish. 
One specimen, the type, from Takao, Formosa, in the Carnegie Museum, meas- 
ures 13$inchesin length. There is also a specimen from Cavite, in the Philippines 
in the Museum of Stanford University. 
This species closely resembles Caranx pluwmbeus (Quoy and Gaimard) from 
which it differs in having a greater number of gill-rakers (14 on lower limb of first 
arch in Carane plwmbeus) and a black anal.

head; eye 44; snout 23; width interorbital space 33; dorsal VII-23; anal II-19; 
pores in lateral line about 127. 
Dorsal contour of body almost evenly rounded from tip of snout to insertion 
of dorsal, there being but a slight elevation at occiput; and a small depression
