We have also examined S. macroptera (Bleeker) from Sumatra, 

 material in the academy, and it differs not only in the short gill- 

 rakers, but also more numerous dorsal rays. S. diissimiieri we have 

 not seen, and it is said to have cycloid scales. Umhrina broussonetii 

 Cuvier is described from " mer du Sud et de la Jamaica," ' though 

 no member of the family is known from Polynesia. Tlie Jamaican 

 fish has 25 soft dorsal and 6 soft anal rays. 



PARALARIMUS, new genus. 



Type. — ParalaHmAis patagonicus^ new species. 



Caudal peduncle slender, rather short. Mouth inclined moderately, 

 cleft not vertical. Lower jaw protrudes. No mental barbels. Teeth 

 permanent in both jaws, sharp, conic, outer enlarged and few upper 

 as canines. Interorbital moderate. Preorbital rather narrow, flat. 

 Preopercle edge membraneous, weakly fringed. Scales of lateral 

 line not noticeably larger than those adjacent or concealed by smaller 

 ones. Caudal moderately scaled basally, naked terminall3\ Pores at 

 snout tip and mandible tip obsolete, (iill-rakers in moderate num- 

 ber, elongate. Pseudobranchiae well developed. Skull firm. Anal 

 inserted posteriorly, small, firet spine nearer caudal base than ventral 

 origin. 



This genus falls in the Sciaeninae. It is allied with Larimus in 

 its moderately firm and not excessively cavernous skull, moderate in- 

 terorbital width, oblique mouth with projecting mandible, maxillary 

 slipping below preorbital nearly its whole length, and general physi- 

 ognomy. It differs in the more or less larger unequal biserial upper 

 teeth. It likewise differs from Odontoscion, which also lias fewer 

 dorsal and anal rays. From Corvula it differs in the absence of 

 canines, and from the fluviatile tropical American Plagloscion, in the 

 scales of the lateral line not larger than those adjacent.
