An analysis of the characters of the species of Seriola is given by me in Proc. U. S. 

 Nat. Mus., 1884, 123. A more recent (unpublislied) study of these fishes by Mr. Enfns 

 L. Green indicates the probable identity of 5. lalandi with S. aliciola {dum<frili), S. 

 falcata with S. rivoliana, and (probably) S. mazatlana with S. dorsalis. 



' Seriola mazatlana Steindachner, Ichth. Beitriige, V. 8, 1876. Mazatlan. 



^^Nematistius Gill. 



(Gill, Proc. Ac. Nat. Sci. Phila., 1862, 258 ; type, Nematistius pectoralis Gill). 



This genus differs from Seriola chiefly in tlie development of the spinous dorsal and 

 pectoral fins, the former being composed of eight very long filamentous spint^s, the 

 latter being acuminate and nearly twice as long as the ventrals. The lateral Hue is 

 nearly straight and is not keeled on the caudal peduncle. Ventral rays, I, 5, the 

 inner ray much branched to the base. Oue species known. Large fishes of an im- 

 posing appearance. 



Nematistius pectoralis Gill, 1. c. Gulf of California to Panama; not rare. 



' Chorinemus alius Giinther, Fishes Centr. Amer., 1869, 433. Mazatlan to Panama.
