BULLETIN OF THE UNITED STATES FISH COMMISSION. 
snout to origin of second dorsal a curve somewhat more convex over the head; along the base of the 
soft dorsal the outline is only slightly convex; ventral outline from tip of lower jaw to origin of soft 
anal nearly straight, obliquely descending; base of anal similar to soft dorsal; depth of caudal peduncle 
less than its width; body compressed, width about 2.5 in head; interorbital equaling eye; eye mostly 
above axis of body, its posterior border halfway from snout to posterior border of opercle; jaws 
subequal, maxillary reaching to vertical through center of pupil; teeth on vomer, palatines and tongue 
villiform, those on jaws in a single series, conical, short, and strong; spinous dorsal with 1 procumbent 
spine and 8 joined spines, the third longest, somewhat more than half of head, its tip reaching tip of 
seventh spine, fourth spine nearly equaling third; soft dorsal and anal falcate, similar in form, the lobe 
about three-fourths of head, base of soft dorsal the longer, 2.5 in body to base of caudal; pectoral 
slender, strongly falcate, length about equaling that of soft dorsal, 1.3 in body; tip of ventrals reaching 
just past vent and one-half distance from origin to origin of soft dorsal; caudal deeply forked, lobes 
equal; anterior portion of lateral line well arched, arched portion of 55 scales reaching about to 
vertical from seventh anal, armed portion straight; armed scutes 32; breast naked except a very small 
patch of small scales in its center; cheek, postocular and upper part of opercle scaled, rest of head 
naked; dorsal and anal scarcely sheathed; gillrakers strong, equaling three-fourths diameter of eye, 13 
developed on lower arm of first arch. 
Color in alcohol, head, body and fins pale, head and body silvery; upper part of caudal peduncle 
dusky; no spot on opercle or on pectoral. Similar to C. hippos, but differing in lacking the opercular 
spot and the spot on pectoral, and in having a larger snout and deeper head. 
This description is based upon a specimen, the type, No. 50710, U. S. N. M. (field No. 749), 9.25 
inches long, taken by me at Honolulu in 1889. Another (field No. 751), 5.5 inches long, is in the 
collection of Dr. Wood, and another (field No. 750), 7.25 inches long, was obtained by Jordan & 
Snyder in 1900 at Honolulu. 
73. Carang'us mar ginatus (Gill). “ Ulna.” 
D. vm-i-20; A. ii-i-17; scutes about 29. 
Color in life (field No. 180), nearly white, with silvery and golden reflections; iris red; a small 
black spot at upper angle of opercular opening; golden areas on preopercle and opercle behind the eye; 
dorsal slightly dusky, lobe of soft dorsal with dusky blotch, remainder of fin yellowish; anal yellow; 
caudal yellow with posterior border dusky ; pectoral transparent; ventral fins white. I have compared 
my single specimen with a specimen of C. rnarginatus from Mazatlan and they seem to be the same.

74. Car angus latus (Agassiz). “Ulua.” 
Head 3.3 in length; depth 2.5; D. vin-23; A. n— i— 19 ; scutes about 38. Color in life, white, upper 
parts with steel-blue reflections, yellowish along the region of the scutes; lower parts silvery; no black 
on or behind opercle; iris yellow; first dorsal yellowish; second dorsal, lobe slightly dusky with bluish 
tinge; caudal slightly dusky with bluish tinge; membranes of anal spines milky white; lobe of anal 
slightly dusky; ventrals white. 
I obtained ten specimens of this fish, ranging from 4 to 9 inches in length; and three, from 3 to 
4.75 inches in length, were taken by the Albatross in 1896. These compared with specimens of C. Inins 
from the west coast of Mexico and from Clarion Island show no differences. The native fishermen do 
not distinguish this species as different from C. rnarginatus, which, with it, is highly prized as a food- 
fish. Both are abundant.

75. Carang'us rhabdotus Jenkins, new species. 
Head 3.5 in length; depth 2.6; eye 3.75 in head; D. i-vin-i-20; A. n-i-16; armed scutes 32. 
Form of body elliptical, the dorsal outline an even curve somewhat more convex than ventral outline; 
greatest depth of head equaling its length; center of eye slightly above axis of body; interorbital 
slightly greater than eye; snout somewhat shorter than eye ; maxillary with supplementary bone
