1,185 A. minimus were dissected for larval filaria but none were found infected. Of 3707 A. jeyporiensis two were infected with what was considered to be larval filaria derived from human sources, and one was infected with two filaria which were not. Out of 187 A. maculatus dissected one harboured a filaria which did not seem to be obtained from human sources. A. hyrcanus was found infected three times in 176 dissections or 1.69% on one occasion in the proboscis.
(4) Pokfulam, Site of New Government Civil Hospital.
At Pokfulam catches were made during the second half of the year in the three matsheds housing the labourers employed in levelling the site of the New Government Civil Hospital. By the end of the year 242 labourers were employed. The Inspector engaged in the catching took thick and thin films of any person found sick in the lines. Results of examinations of Blood Films and catches for Pokfulam are found in Tables XX and XXI.
Of the five cases found with parasites in the blood, one had recently come from a malarious area, two had lived long enough on the site to have contracted malaria there, and no information had been obtained from the other two.
Several surveys have been done within the circle of half a mile radius from the site from 1931 onwards. Larvae of A. maculatus were found in abundance on all occasions and very few larvae of A. minimus except in the surveys done in the cold weather when they were found in comparatively large numbers in a small sector in the neighbourhood of the junction of Island and Mount Davis Roads. In this small sector 19 out of 26 children examined in 1931 had enlarged spleens or 73%. In the larger sector of the half mile circle 124 children were examined; three had enlarged spleens or 2.4%. The matsheds are situated about 650 yards from the A. minimus breeding places, but there are several huts of a primitive type in between which no doubt have greater claim on the attentions of these mosquitoes. As will be seen very few Anophelines were captured on each occasion hence it was not considered necessary to make catches more frequently. All the mosquitoes were dissected and in December one A. minimus was found to be heavily infected in the salivary glands.
No complaints as to malaria were received from the residents in the neighbourhood.
(5) Tai Hang Road, (an East-end suburb of Victoria).
Catches were made from July onwards. 62 labourers engaged in building operations were housed in two matsheds on the spur above the Tai Hang Road in the vicinity of the Tai Hang nullah. As before blood films were taken of any sick. Two
