REPORT ON FISHES COLLECTED IN THE HAWAIIAN ISLANDS. 421 
of mouth with 5 tentacles; nostrils large, the border of the broad nasal flap with a fine fringe; 
interorbital space broad, more or less flattened, gill-openings of about equal length, the fifth on a level 
with greatest width of disk; body and tail everywhere smooth; caudal spine broad, flattened, serrated 
at the sides, longer than interorbital space; tail broad and flattened anteriorly, very slender posterior 
to spine, its length 1.6 the disk, a cutaneous fold above and below, the latter beginning below base of 
dorsal spine; pectoral rounded obtusely; ventrals broad, their width but little less than their height. 
Color in alcohol, dark brown above; body, upper parts of sides, pectorals and ventrals light 
brown, lighter toward margins; body and fins white underneath; cutaneous folds black. 
Only one specimen obtained. Length of disk 6.5 inches; length of tail 10.5 inches; width of 
disk 8 inches. 
This description is based on the type deposited in the U. S. N. M. (original No. 547), obtained 
by me at Honolulu. 
5. Dasyatis sciera Jenkins, new species. 
Tip of snout (measured to orbit) 3.5 in disk; interorbital 2.25. Body rhomboid, the width of 
disk greater than its length, the greatest width somewhat in front of the center of its length; head 
very broad, the anterior margins of the disk nearly straight, slightly convex, meeting at tip of snout 
at a very obtuse angle, the tip with a slightly projecting point; outer angle of disk slightly rounded, 
the lateral margins very slightly rounded; mouth small, slightly undulated, 2.2 in interorbital; about 
30 teeth in upper jaw, in a very oblique series, about 24 in lower; upper buccal flap with broad fringe; 
8 tentacles on floor of mouth, 4 median and 2 on each side; nasal flap with a fine fringe; nostrils large; 
interorbital space somewhat flattened, concave in the middle; gill-openings of about equal length, the 
fourth in line with the greatest width of disk; body everywhere smooth, with no indications of spines 
or plates; distal half of tail with small, sharp tubercles above and on sides (caudal spine hail been 
removed before the specimen was received by me); length of tail more than twice that of disk, a 
cutaneous fold below only. 
Color in alcohol, upper side of disk uniformly light brown; tail darker; under side of disk white. 
The single specimen secured measures 13 inches to base of tail, the latter measuring 29 inches. A 
skate without the tail is in the collection made by the Fur-Seal Commission. It corresponds with the 
type in all particulars and is doubtless the same species. 
Type deposited in the U. S. N. M. (original No. 387), Honolulu. 
Family IV. MYLI0BATID4J. 
6. Aetobatus narinari (Euphrasen). 
This beautiful ray is not uncommon at Honolulu, and occasionally large examples are exposed for 
sale in the market. The single example obtained measured 15.5 inches to base of tail, the tail being 
32.5 inches long; disk more than twice as broad as long; anterior borders slightly convex, the posterior 
slightly concave; outer angles pointed; origin of dorsal fin a short distance back of posterior attached 
margin of ventrals; ventrals nearly twice as long as broad; fontanelle on top of head gradually 
narrowing backward. 
Color of disk, blue above, covered with numerous distinct white ocellus-like spots as large as eye; 
no spots on head in front of spiracles; white below; teeth in lower jaw bent, an obtuse angle projecting 
forward; about 5 teeth of lower jaw projecting beyond those of upper.

7. Leptocephalus marginatus (Valenciennes). “ Puhi-uha.” 
Fairly common at Honolulu and apparently valued as food by the natives. I saw one in the 
market, 5 feet in length, for which $1 was asked. Four specimens were obtained, Nos. 175, 20 inches 
long, 2041, 21 inches; 2042, 23 inches; and 2043, 26 inches in length. 
Color in life of No. 175, back to below lateral line light; under parts white; dorsal fin light brown; 
anal fin white anteriorly but gradually shading posteriorly to light brown; outer margin of dorsal,
