NO. 1919. FISHES FROM JAVA— BEAN AND WEED. 591 



both founded on fishes of the same genus unless SardineUa was founded 

 on the young of Clupea, but the type of the former is easier to deter- 

 mine. 



In tliis group Bleeker has recognized a great number of species 

 which we are utterly unable to separate with the material at hand. 

 Many of our specimens seem to show intermediate characters and it 

 woyld be only by an examination of a much longer series that they 

 could be separated. 



HARENGULA PERFORATA (Cantor), 



Plate 75, fig. 1. 



Twenty-one specimens, 100 to 110 mm. long. Batavia. These 

 specimens evidently represent the species described by Cantor as 

 Clupeonia perforata, but our specimens seem to fit about equally well 

 Bleeker's descriptions of several forms which he puts in several 

 genera. 



HARENGULA ARGYROT-ENIA (Bleeker). 



Two small specimens from Batavia, 71 and 85 mm. long, appar- 

 ently represent the form described by Bleeker as Clupea (Ilarengula) 

 argyrotxnm} It may also be the same fish as the one described under 

 the name Clupea dispilonotus ?■ 



ILISHA INDICA (Swainson). 



Plate 75, fig. 3. 



Fifteen specimens from Batavia, 90 to 170 mm. long, seem to agree 

 fairly well with the description and figure of this species as given by 

 Bleeker.' 



One additional specimen from Pclabocan Ratoe, m very bad shape, 

 seems to be this species. Native name of this specimen given as 

 Z'Bu-ro-nuk." 



ILISHA ELONGATA (Bennett). 



One small specimen from Batavia, 90 mm. long, in bad shape, is 

 doubtfull}'' referred to this species on the basis of the descriptions and 

 figures in Bleeker.* 



OPISTHOPTERUS TARTOOR (Cuvier and Valenciennes). 



One specimen from Pelaboean Ratoe, Wynkoop Bay, 140 mm. 

 long. Native name given as ' ' Dow-in-a-wi." 



In the discussion of the species Bleeker ^ expresses doubt as to 

 whether it is the same as the tarioore of Russell and suggests the name 

 0. valenciennesi if it is different. We are inclined to agree with this 

 conclusion, but have not sufficient material to prove the case.
