SUNIER: Marine fish-ponds of Batavia. 227 
To the “ûget” (bandeng-fry) the kepala timah (Haplochilus panchax 
(HAM. BUCH.), cf. Chapters VI and VII) is also dangerous. This little fish 
which is so very common in the Batavia empangs, is accordingly kept 
very carefully out of the fry-ponds. 
Undoubtedly the above list of enemies of the bandeng reared in the 
Batavia empangs is very incomplete. (see Appendix to Chapter V, page 302). 
CHAPTER VI. 
The Cyprinodontidae of the Batavia Empangs. 
§ 1, Haplochilus panchax (Ham. Buch.) and Haplochilus javanicus (Blkr.). 
Among the fishes which are practically speaking always met with in 
the marine fish-ponds of Batavia, the first to be mentioned are two species 
of Cyprinodontidae, viz. Haplochilus panchax (HAM. BUCH.) and Haplochilus 
javanicus (BLKR.)') (cf. fig. 14, 15 and 16). | 
Of these two species the one that is by far the more numerously re- 
presented in the Batavia sea-fish ponds is Maplochilus panchax. It occurs 
rarely that standing at the edge of a bandeng-pond one fails to catch

sight at once of several specimens of this little fish. The young individuals 
are frequently seen swimming past in shoals of hundreds, Accordingly I 
have chiefly turned my attention to this species. 
At Batavia and in West-Java generally Haplochilus panchax is called 
“kepala timah”?) which might be freely rendered by “the little fish with 
the white-metallic shining spot on its head.” According to GRONEMAN (2) 
the name in Central-Java is “wader tjéto”. In JANSZ’ dictionary (°°) 
I found the name “tjétaq” = “a small river-fish about the size of teri °), 
1) In BLEEKER’s (4) Atlas Ichthyologique, Haplochilus panchax = Panchax bucha- 
nani C. V., whilst Haplochilus javanicus = Aplocheilus javanicus BLKR.. For the many 
other synonyms of Haplochilus panchax reference should be made to the systematic 
literature on the subject. 
2) kepala = head; timah = lead. 
3) teri = Stolephorus spp.
