JORDAN AND RICHARDSON: FISHES OF THE ISLAND OF FORMOSA J 65 



14. Dasyatis akajei (Schlegel). 

 Formosa (Jordan & Evermann). 



Family ELOPIDJ: 



15. Elops hawaiiensis Regan. (Plate LXVI, upper figure.) 



Depth 6.8 ; head 4.2 ; snout a Iitte 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, witli 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 widtli over the tip of the anal scarcely less than its depth; 

 least depth of caudal peduncle 3^ in head, least width 6. 



One specimen thirty-six inches and one twelve inches long were received from 

 Takao. The larger specimen seems to agree well with one thirty-four inches long 

 recorded by Evermann 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 machnatu, which is the species of the Red Sea. 



Family MEGALOPID.E. 



15. Megalops cyprinoides (Broussonet). 

 Giran, Formosa (Jordan & Evermann). 



Family CHIROCENTRIDJ-;. 



16. Chirocentrus dorab (Forskal). 

 (Native name Sax do). 



One specimen twenty-two inches and two sixteen inches long from Takao.
