(Observation-table). Combined data concerning the salinity 
of the pond-water, the production of Anophelines and the 
composition of the submerged vegetation, collected in the 
Batavia sea fish ponds. 
Salinities and quantitative data concerning the production 
of Anophelines, collected in the Batavia marine fish ponds 
in 1918 and 1919 and arranged topographically and in the 
order of the salinities; with for each 10°/, (or 5 °/o9) of 
the salinity the average of the mosquito-net catches per 
10 M? and per night and the total of the Anopheline © © 
emerged from the larvae and pupae collected. 
Topographically and chronologically arranged data concer- 
ning salinities and Anophelines, collected in the Batavia 
sea fish ponds in 1918 and 1919; with monthly averages 
of the salinities and of the mosquito-net catches per 10 M? 
and per night and monthly totals of the Anopheline QQ 
emerged from the larvae and pupae collected.- 
Average number of 99 of Myzomyia ludlowi THEOBALD 
captured by means of mosquito-nets per 10 M? and per 
. night at different salinities. 
Average number of 2% of Myzomyia rossii GILES captured 
by means of mosquito-nets per 10 M? and per night at 
different salinities. 
Monthly averages of the numbers of 22 of Myzomyia 
ludlowi THEOBALD and of Myzomyia rossii GILES captured 
by means of mosquito-nets per 10 M? and per night. 
Number of 99 of Myzomyia ludlowi THEOBALD per 10022 
of Myzomyia rossii GILES at different salinities. Mosquito- 
net catches and imagines emerged from larvae and pupae 
collected. 
Number of 99 of Myzomyia ludlowi THEOBALD per 100 99 
of Myzomyia rossii GILES in different months. Mosquito- 
net catches and imagines emerged from larvae and pupae 
collected. 
Averages and other resultant figures concerning salinities 
and Anophelines, derived from the Tables VIIA, VIIB 
and IX and relating to the entire Batavia empang zone.
