58. Caranx latus Agassiz. Horse Eye Jack. 



Caranx latus Agassiz, Pise. Bras., 105, 1829 (Brazil) ; Jordan & Evermann, 

 Fishes of North America, 923. 



In a specimen 20 in. long the opercular spot is nearly obsolete, 

 and the adipose eyelid is highly developed on hinder side of eye. 



59. Alectis ciliaris (Bloch). 



Zeusciliaris Bloch, Ichthyol., VI, 27, pi. 191, 1788 (East Indies). 

 Alectis ciliaris, Jordan & Evermann, Fishes of North America, 931. 



60. Vomer spixi (Swainson). 



Platysomus spixii Swainson, Class'n Fishes, 250, 406, 1839 (Brazil, after 

 Agassiz and Spix). Vomer gabo?iensis Guichenot, Ann. Soc Maine et Loire, 

 1865, 42 (Gaboon). 



Head 2f ; depth If ; dorsal VI-I, 22 ; anal I, 18 ; eye 3| in head ; 

 maxillary 2£ ; snout 1J ; caudal 1. 



Body very deep, in form much like Selene cerstedi, profile very 

 steep almost vertical, snout slightly protruding, mouth oblique, max- 

 illary reaching to the vertical from front of eye, gill rakers 7+27, 

 the longest little more than half eye. 



Lateral line strongly arched in front, the arch H the straight 

 part ; plates of lateral line little differentiated ; pectoral falcate, as 

 long or slightly longer than head; ventrals small, under base of 

 pectorals. 



Color bluish above, sides silvery, fins except ventrals and anal 

 dusky. Here described from specimens from Jamaica about 10 

 inches in length. 



These specimens are evidently different from the northern Vomer 

 setipinnis (=Vomer broivni), the body in specimens of the same 

 length being much deeper. It corresponds to the figure given by 

 Agassiz of Vomer broivni, this figure being the basis of spixii 

 of Swainson. Probably all West Indian records of Vomer setipinnis 

 belong to Vomer spixi. 



61. Selene vomer (Linnaeus). , 



Zeus vo?ner Linnreus, Syst. Nat., X, 266, 1753 (America). 



Selene vomer, Jordan & Evermann, Fishes of North America, 939. 



62. Chloroscombrus ectenurus Jordan & Osgood, Ms. New species. 



Chloroscombrus chrysurus of authors, not of Linnaeus. 



Micropteryx cosmopolita Agassiz, not Setiola cosmopolita Cuvier, who bases the 

 name on Scomber chloris Bloch, an African species from Acara, Guinea, Coll. 

 Dr. Isert.
