the head one-third. Snout obtuse, not much longer than the eye ; 
cleft of the mouth small, the maxillary extending to the vertical 
from the anterior margin of the orbit. Lips thick ; a pair of pores 
on the symphysis of the lower jaw, a central groove behind it. Snout 
naked, the remainder of the head being scaly. The width of the 
interorbital space is much less than that of the orbit. Dorsal and 
anal spines exceedingly strong; the third of the dorsal fin is the 
longest, and nearly two-thirds as long as the head. The second anal 
spine is much longer than the third, and a little shorter (but stronger) 
than the third of the dorsal fin. Each ray of the soft fins is accom- 
panied by a series of minute scales, but only on the caudal fin are 
these scales dense enough to cover the rays. Caudal fin slightly 
emarginate. Silvery, with four black cross bands: the first runs 
from the occiput through the eye to behind the angle of the mouth; 
the second from before the dorsal fin to below the base of the pec- 
toral; the third from the base of the sixth, seventh, and eighth 
dorsal spines to the vent; the fourth descends from the origin of the 
soft dorsal to that of the soft anal. Fins blackish. 
Only one specimen, 83 inches long, is in the collection.

8. CarAnx, n. sp. There is a young specimen in the collection 
which appears to belong to an undescribed species closely allied to 
C. Carangus and C. Hippos. 
9, CARANX LEUCURUS, 0. sp. 
D. 8|5. A. 2\—.. Very closely allied to C. bicolor. The first 
dorsal fin is composed of short, stoutish spines, the fourth of which 
is the longest, but scarcely longer than the eye. The soft dorsal and 
anal are rather elevated ; the caudal is emarginate, and has the lobes 
rounded. Teeth very small, forming a single series in both jaws ; 
palate smooth. The height of the body is one-half of the total 
length (without caudal), the length of the head one-third. Snout 
rather obtuse, the jaws being equal in front when the mouth is 
closed ; the maxillary extends to below the anterior margin of the 
orbit. The lateral line makes anteriorly a subsemicircular curve, 
the width of which is contained from 12 to 14 times in the length of 
the straight portion; it becomes straight behind the vertical from 
the origin of the second dorsal, and is armed with about fifty small 
and low shields, only a few of which terminate in a depressed spine. 
The pectoral fin extends to the anal spines. Brownish grey, body 
with six dark-brown vertical bands: the first crosses the body behind 
the base of the pectoral, and the fourth descends from the middle of 
the soft dorsal fin. Operculum with a large black spot. Dorsal, 
anal, and ventral black ; pectoral and caudal whitish. 
Only two young specimens are in the collection, the larger being 
3 inches long.
