toral than base of caudal, and anterior rays elevated. Spine weak. 

 Finlets of both dorsal and anal similar, at equal distances, and last 

 longest. Anal similar to soft dorsal, inserted about midway between 

 origin of pectoral and base of caudal, or a little behind origin of 

 soft dorsal. Pectoral high, small, and reaching beyond middle of 

 base of spinous dorsal. Ventral low, inserted a trifle behind(?) origin 

 of pectoral. Caudal small, deeply emarginate. 



Color when fresh in arrack, blue-black above, with many round deep 

 or darker spots than body-color, and area above well separated from 

 lower surface of bodj-^ by a sharp line of demarcation which reaches 

 lateral line below first -finlets. Sides of head, trunk, and caudal pedun- 

 cle, together with all of lower surface of bod}^, silvery- white. Dorsal, 

 caudal and pectoral grayish, latter especially on its outer and inside 

 basally blackish. Ventral and anal whitish. Inside of gill-opening 

 grayish. Peritoneum silvery. 



Length 8^ inches. 



Thirty-one examples, but all of the others young. Padang, Sumatra. 

 Coll. A. C. Harrison, Jr., and Dr. H. M. Hiller. Acad. Nat. Sci. 

 Phila. and Stanford University. In the example described above 

 I found a small Lciognathus ly\ inches in length. It was taken from 

 the gullet. 



I provisionally adopt the name Scomber kanagurta, though derived 

 from Russell's Indian fish^ and based on that of the Red Sea by Riippell, 

 who subsequently described S. chrysozonus^ and S. microlepidotus^ 

 from the same place. Kner recorded the latter from the Nicobars 

 and Hong Kong,* and Bleeker from Pinang.^ Dr. Steindachner con- 

 siders both identical wdth S. loo,^ and Day^ united all three with 

 S. kanagurta, S. moluccensis,^ and S. reani,^ though Dr. Klunzinger 

 separated S. microlepidotus, retaining S. kanagurta and S. chrysozonus 

 as distinct. 



Dr. i\Ieek records microlepidotus from Aden.^° One of his examples 

 now in the Museum of Stanford University I have examined. It has 

 exceedingly long gill-rakers, the longest almost equal to snout and one-
