It has been found difficult to understand how such a fragile creature as an Anopheline larva could withstand the force of a strong current of water. In the following article it is proposed to explain the phenomenon on anatomical grounds.
* In this connection it is noteworthy that, whereas in the fully-grown larvae of A. hyrcanus and A. barbirostris (open-country breeders) the pigmented elements of both larval and imaginal eyes reach a maximum development, in the case of A. umbrosus, the remaining Malayan representative of the Myzorhynchus group of Anophelines (a breeder by preference in jungle), they are much reduced in size, especially in the crescentic eye, in which indeed they are so pale that the determination of their presence is difficult.
