At Batavia, fishponds in a well-drained littoral area may be harmless 

 as a source of malaria if (1) only sea- water is allowed to enter the 

 ponds, in order to keep the salt-content as high as possible ; (2) a 

 suflicient number of the fish, Chanos chanos, is kept in the ponds to 

 ensure that all under-water and other vegetation is eaten ; (3) care is 

 taken that, besides the other fish bred in the ponds, asufficient quantity 

 of Haplochilus panchax is maintained. Such harmless fishponds are 

 to be found north of Batavia. Their drawback is that there is no 

 excess of vegetation as food for C. chanos, which is therefore of less 

 market value. Artificial food might solve this difficulty. 



From a hygienic standpoint, however, the abolition of the ponds is 

 the only satisfactory measure.

Attention is drawn to the skin affection caused by Pediciiloides 



ventricosus. The cases under observation were amongst men handling 



sacks of corn, the mites being found on the sacking. Treatment with 



a lotion of warm water and vinegar proved effective.

The establishment of a new malarial centre in the county of Var is 

 recorded. The 15 cases of primar}^ infection here described had never 

 previously resided in any known malarial district. Anopheles 

 macnlipennis is apparently abundant in the area under discussion, 

 and the climatic conditions are favourable to development of the 

 malarial parasite. This was probably introduced into the locality 

 by infected troops passing through it.

Attention is drawn to the finding of the female of a species of 

 Phlehotomus at Bron- Village (Rhone). Owing to lack of information 

 regarding the specific characters of the females of this genus, the 

 species cannot be identified with certainty. It does not agree with 

 Franga's description of the female of P. papatasii. The individuals were 

 caught in August, and it was observed that if the temperature dropped 

 appreciably below 20° C. [68° F.] for several days, the midges dis- 

 appeared. 



Commenting on this paper M. Roubaud remarks that a 

 species apparently resembling the above was caught by him at 

 Clermont-Ferrand.

Tahanus ncmoralis var. ruficornis, n., is described from Algeria,
