of the commonest species, and six specimens were preserved for the 

 Siamese Bureau of Fisheries; in life the back had a rich, pale blue 

 color, and the dorsal and caudal fins were black-edged. In some 

 specimens there is a black tip to the anal fin. The type specimen was 

 37 cm. long. 



The largest local examples have been 19 cm. long, with many 10 to 

 14 cm. 



In the Thai vernacular the fish shares with Cycloclieilichthys the 

 names pla nam lang and pla takok; a local name used at Bang Sai is 

 pla takok dok chok. 



Genus KAMPALA van Hasselt 



Hampala van Hasselt, Alg. Konst. Letterbode, vol. 2, No. 35, p. 132, 1823. (Type, 

 Eampala macrolepidota van Hasselt.) 



One may follow Bleeker in crediting this generic name to van 

 Hasselt, rather than to Bleeker, as has been done by Weber and de 

 Beaufort. Of the two local forms, keyed below, one has a wide Orien- 

 tal distribution, the other is restricted to Eastern Thailand and Cam- 

 bodia.

 dorsal rays and ventral fin ; each caudal lobe with a sharply defined black

 eye; caudal lobes of equal length macrolepidota 



16. Adult with body marked by a roundish blackish spot above lateral line between 

 dorsal and ventral fins ; no sharply defined black marginal band on caudal 

 lobes, which are distally diffused blackish ; maxillary barbels less than half

The range of this species includes Java, Sumatra, Borneo, Malaya, 

 r>iirma, French Indo-Cliina, and Tliailand. In Thailand it is found 

 throughout the length and breadth of the country in streams and 

 lakes. In some places and during certain seasons it may be very 

 abundant and constitute an important part of the commercial catch. 

 Specimens have been examined from the Patani River and Tale Sap 

 in the Peninsula ; from numerous places in the central plain, includ- 

 ing Bung Borapet; from the Meping in the Northern area; from the
