3S Mr. C. T. Regan— ^ Revision of 



with 11 or 12 branched rays; pectoral ^ or a little more than 

 \ the length of head, extending | or less than ^ of the distance 

 from its base to the pelvics ; origin of pelvics a little nearer 

 to base of caudal than to end of snout. Least depth of caudal 

 peduncle ^ the length of head, 78 or 79 vertebiai *. 



Atlantic coast of America from the Unitcfl States to Brazil. 



Here described from eight specimens, 160 to C20 mm. in 

 total length, from Wood's Hole, Cuba, St. Croix, and Rio 

 Janeiro. 



2. EIops ojffinis, sp. n. 



Differs from the preceding species in having IS to 20 gill- 

 rakers on the lower part of the anterior arch, but is extremely 

 similar to it in other respects. 79 vertebrae. 



Pacific coast of Mexico, and probably from California to 

 Ecuador. 



Two specimens, 230 and 320 mm. in total length, from 

 Mazatlan {Jordan) and Jalisco {Duller). 



3. Elops senegalensis, sp. n. 



Depth of body nearly 5 in the length, length of head 3| 

 to 4. Snout as long as or longer than eye, the diameter of 

 which is 4^ to 5j in the length of head ; interorbital width 

 5 to 5^ in the lengtli of head. Maxillary extending beyond 

 the eye; lower jaw ii'duded, the whole of the preemaxillary 

 band of teeth exposed when the mouth is closed ; length of 

 gular plate { to | that of tiie lower jaw, which is nearly | 

 that of the head; 30 to 33 branchiostegals ; 12 to 14 gill- 

 rakers on the lower part of the anterior arch. 94 to 98 scales 

 in a longitudinal series. Dorsal 23-26, with 17 to 20 

 - branched rays ; anal 16-17, with 12 or 13 branched ra3-s; 

 pectoral I the length of head, extending a little more than ^ 

 of I'iie distance from its base to the pelvics ; origin of pelvics 

 equidistant from end of snout and base of caudal. Least 

 depth of caudal peduncle more than ^ the length of head. 

 69 verteWas. 



West Af.'ica. 



Three specimens, 170 to 320 ram. in total length, from 

 St. Louis, Senegal (Belhez). 



* The last three veitebrae included in my count are directed upwards, 

 but have distinct and separate centra, ■v\hich, however, are overlapped by 

 the bases of the enlarged'^.neural spines which support the upper caudal 

 fin-rays, so that by some thfi&e three vertebrae might be reckoned together 

 as hypural. \
