ARGENTINA BRUCEI, NEW SPECIES 



Figures 2, 3, 4, 5, 8, 9, lOD, 13 



Argentina striata not of Goode and Bean, 1896 ; 

 Cohen, 1964 (fig. 5). 



Diagnosis 



A. hrucei differs from sphyraena and silus in 

 having smooth instead of spiny scales and five in- 

 stead of six brancliiostegal rays. It differs from 

 sUus, sialis, aliceae, and elongata in having seven 

 (sometimes six) gill rakers on the lower arm of 

 the first arch rather than eight or more. It differs 

 from all Argentina except sphyraena and aliceae 



in its low vertebral count, 44 to 46 rather than 47 

 or more. It differs from sphyraena, sialis, elongata, 

 australiae, and kagoshimae in having 18 to 20 

 pectoral rays rather than 19 or fewer. It differs 

 from elongata, kagosKirrme, and euchus in having 

 13 or 14 ventral rays rather than 12 or fewer. It 

 differs from australiae, kagoshimae, eiichus, 

 stnata, georgei, and stewarti in having usually 

 seven gill rakers rather than usually six gill rakers. 

 It differs from stnata in usually lacking silvery 

 pigment on the swimbladder.

 Measurements 



Based on about 72 specimens, 68.4 to 132 mm. 

 standard length, given as percent of standard 

 length: Preanal 84.5 (74.6-87.9); preventral 56.2 

 (52.9-58.8); predorsal 48.3 (44.4-50.7); head 

 length 31.2 (27.7-33.1) ; snout 10.1 (8.7-11.2) ; eye 

 10.0 (7.9-11.6); maxillary length 5.9 (4.6-6.6); 

 depth at dorsal fin 13.0 (10.9-15.4) ; depth at cau- 

 dal peduncle 5.9 (5.0-6.5). 



Description 



A relatively short-bodied species with greatest 

 depth at dorsal origin tapering to caudal peduncle. 

 Body in cross section deeper than wide, the ventei- 

 broadly rounded. Body in preserved specimens 

 notably soft. The head, when viewed laterally, 

 usually has its dorsal profile broken by the upper 

 margin of the eye. The dorsal and ventral profiles 

 of the head converge on the snout at about equal 

 angles. The interorbital space between the supra- 

 ocular canals is flat. Tlie dorsal portion of the
