25% of the larvae obtained were A. minimus, in one collection made in October 70% were A. minimus.
102. In a survey made in one of the branches of this stream, over 300 A. aitkeni larvae were collected. It is unusual to obtain this larvae in such numbers in the course of a survey in one area.
Repulse Bay.
103. Several surveys were done in the stream which runs beneath Island Road and Beach Road east of the Lido, between R.B.L. 168 and R.B.L. 182. Larvae of A. maculatus and A. minimus could usually be found; on one occasion 223 larvae of A. minimus were collected from it.
104. Middle Beach (Repulse Bay). Whilst the road was under construction in 1934, malaria was found to occur amongst the labourers engaged in making it. A stream adjacent to the labourers' matsheds, harboured large numbers of A. minimus larvae at times, and infected A. minimus were found in the matsheds. After the labourers had left, several surveys were done in the stream and A. minimus larvae were found in abundance. A number of bathing matsheds were erected in the vicinity. In the autumn seven people who took part in a moonlight picnic are said to have contracted malaria there; this stream will be a source of danger until it is properly dealt with.
Village of Wong Ma Kok, Stanley Peninsula.
105. The surroundings of this village were investigated in July. Larval surveys were done in the adjacent wet cultivation, fallow rice fields, and stream, only a few larvae of A. hyrcanus and A. maculatus were obtained. No Anophelines were captured in this village. Two out of seven children examined had enlarged spleens, one of these had come from Tai Po recently, the other had resided in the village for four years.

106. A complaint of the occurrence of malaria was reported by the Water Authority, P.W.D., in October. Thick blood films were taken from 30 residents, 18 contained malarial parasites. A larval survey was done within a circle of half mile radius from the station, streams were found to harbour the larvae of A. maculatus and A. minimus,
107. Arrangements were made with the P.W.D. for the clearing and oiling of breeding places. This work was done under the direct supervision of the Assistant to Malariologist who, as a Sanitary Inspector, has had extensive experience of such work in Malaya. The labour force and materials were supplied by the P.W.D.
