650 FISHES FROM ST. LUCIA, WEST INDIES JORDAN. 



genus by Everrnann and Meek (Proc. Ac. Nat. Sci., Phila., 1886, 261), 

 Gerres harei\gulus, as represented by specimens from Florida and Cuba, 

 was referred to the syuouymy of the west coast Gerres gracilis. The 

 two species are very closely related. A comparison of specimens show 

 that G. liarengulus has a blunter suout, somewhat larger eye, aud larger 

 anal spines than G. gracilis. Eye, 21 in head ; snout, f ; second anal 

 spine, 2§ to 3£ in head iu G. harengulus from Key West; (3^, 3^, 4J in 

 G. gracilis from Guaymas). It is, however, not always possible to dis- 

 tinguish G. harengulus, G. pseudogula, G. gracilis and G. dowi, and per- 

 haps all should be regarded as varieties of one, G. gracilis.

70. Sparisoma hoplomystax (Cope).

Abundant, as is also the next species. The fact of the wide distribu- 

 tion of these two species is an interesting one, as until very lately both 

 have been overlooked or else not intelligibly described. 



71. Sparisoma xystrodon Jordan & Swain. 



72. Scarus cceruleus (Bloch). 



73. Scarus croicensis (Bloch). 



One young specimen.
