WESTERN ATLANTIC PERCOPHIDID FISHES — GINSBURG 633 



as compared with those of the five Western Atlantic species given in 

 tables 1-3 show that the extralhnital species examined are different. 

 Also, in three of these species, excluding caudimacula, the first spine 

 is filamentous and prolonged, while among the Atlantic species only 

 anatirostris is now known to have a prolonged dorsal spine, and in 

 that species it is the second instead of the first spine that is prolonged 

 in large males. 



Beinbrops magnisquatnis, new species 



Description.— D VI; 15. A 17. P 24. Sc 47. GR 4-5 + 14. Fin ray 

 counts the same in both available specimens. Scales in 47 rows 

 over lateral line in holotype; some scales missing in paratype and 

 number not definitely determinable, but approximately the same. 

 Anterior gill rakers in the smaller specimen (paratype) short, slender,

 snout divided by that of the eye in three Western Atlantic species of Bembrops, 

 segregated in size groups 



graduated, not tuberclelike; in larger specimen end outgrowth on upper 

 limb a low tubercle, anteriormost one on lower limb intermediate in 

 development. 



Following are the proportional measurements of the holotype and 

 paratype, respectively (caudal, pectoral, and pelvic damaged in both 

 specim.ens) : Depth 14.5, 13.5; peduncle 6.3, 6.0; head 36, 34; maxillary 

 14.5, 13.3; snout 10.2, 8.9; eye 10.5, 9.6. 



First dorsal with a large subtriangular black spot at its base extend- 

 ing from first interspinal membrane to fifth spine, a whitish area above 

 spot, anterior produced part above whitish area again black; a similar 

 smaller black spot at base of second dorsal from first interradial mem- 

 brane to third ray; in gross effect the tw^o spots appearing partly
