JORDAN AND RICHARDSON: FISHES OF THE ISLAND OF FORMOSA 165 
14. Dasyatis akajei (Schlegel). 
Formosa (Jordan & Evermann). 
Family ELOPID A. 
15. Elops hawaiiensis Regan. (Plate LX VI, upper figure.) 
Depth 6.8; head 4.2; snout a litte longer than eye, the transverse diameter of 
which is 3 in maxillary; interorbital width (measured on skull) a little over 
5 in head; maxillary extending beyond eye, more than one-half length of head ; 
lower jaw shutting inside upper (tip slightly projecting), so that the whole of the 
premaxillary band of teeth is exposed when the mouth is closed ; length of gular 
plate two-thirds that of lower jaw; twenty-seven branchiostegals; thirteen  gill- 
rakers on lower limb of anterior arch; ninety-seven scales in a longitudinal series 
from gill-opening to the base of the caudal; dorsal twenty-three, with nineteen 
branched rays; anal fifteen, with twelve branched rays; pectoral one-half width of 
pupil, more than one-half length of head, extending three-sevenths of the distance 
from its insertion to the front of the ventrals; origin of the ventrals slightly nearer 
the base of the caudal than the end of the snout; caudal peduncle scarcely com- 
pressed anteriorly, its width over the tip of the anal scarcely less than its depth; 
least depth of caudal peduncle 34 in head, least width 6. 
One specimen thirty-six inches and one twelve inches long were received from 
Takao, he larger specimen seems to agree well with one thirty-four inches long 
recorded by Evyermann and Seale (1906) from the Philippines, measurements of 
which have been furnished by Dr. Evermann. Specimens in the museum of Stan- 
ford University from Honolulu and Manila seem also to belong to this species, 
though none of these is over fourteen inches in length. In specimens of that size 
and under the body is notably less slender and the caudal peduncle much more 
compressed than in the adult specimen here recorded from Formosa. 
This species is recorded by Jordan & Evermann from Suwata, Formosa, as 
Elops machnata, which is the species of the Red Sea.
