There is a considerable difference in number and arrangement of 

 gill-rakers in the various species of Oligoplites and Scomheroides, but 

 it seems to have no generic value. 



The genus Eleria Jordan and Scale, based on the presence near the 

 symphysis of the mandible of a pair of diverging canine teeth, is a 

 synonym of Scomheroides. These teeth are matched by a similar 

 pair in the upper jaw of specimens less than 150 mm. long. Soon 

 after reaching this size the mandibular pair of canines disappear 

 while those on the premaxillary persist until the fish is about 180 

 mm. long. 



Eleria i)hili'p'pina, the type-species, is a synonym of Scomheroides 

 lysan. 



SCOMBER KANAGURTA (Russell). 



Twenty-eight specimens, 110 to 200 mm. long. Batavia. 



Identified by J. T. Nichols as S. hrachysoma and ;S'. microlepidotus. 

 Scomher hracliysoma Bleeker is an exceedingly rare fish in Java 

 (Bleeker had only one specimen) and difi^ers from all of these speci- 

 mens in much greater depth and in the absence of all spotting on 

 the back. 



Scomher microlepidotus is apparently the young of ;S^. chrysozonus, 

 and tliis name is therefore not tenable. 



We have examined in addition to these Java fish, one which was 

 identified by Bleeker as Scomber Tcanagurta, two identified by Alvin 

 Scale as S. loo, and eight identified by Scale as S. microlejndotus. The 

 ones called loo are much larger and show a slightly different color 

 pattern, but otherwise we can see no other specific differences in any 

 grouping of the entire lot. We are entirely unable to determine the 

 basis of Nichols's division of the specimens he examined. 



We have carefully examined the paper by Dr. P. N. Van Kampen,^ 

 and agree with him that Scomher Jcamigurta,^ S. loo, S. microlepi- 

 dotus, S. moluccensis, S. cJirysozonus, and S. reani, should all be 

 included under the single name S. Tcanagurta, but we differ from him 

 in including his S. neglectus in the list. 



Another specimen (No. 56090) labeled Scomher hrachysomu (prob- 

 ably identified by Alvin Scale) is evidently Van Kampen's S. neglec- 

 tus, wliich we include in S. Tcanagurta, as our specimens from Batavia, 

 Java, show all the intermediate conditions. 



Mr. E. C. Starks, after an examination of the skull of each of these 

 species and of Scomher scomhrus, said that he saw no reason in this 

 case for generic separation of the two. This leaves hracliysoma alone 

 in the genus BastreUiger.
