Remarks. Of all the races of Rh. affinis, the Himalayan form (Rh. a. himalayanus) is the most ordinary-looking: in the horse-shoe, the ears, the nasal swellings, the brain-case. There can hardly be any doubt that the affinis type originated in the Himalayas, and from there spread eastwards to S. China, south-eastwards through Indo-China, as far as Lombok. Geographical races. There are, at least, seven forms of Rh. affinis, differing in certain cranial characters, in the size of the ears and horse-shoe, in the length of the tail and tibia, in general size, and in geographical habitat. Some of these forms may be called distinct species by other authors. 13 a. R hinolophus affinis himalayanus, subsp. n. (Plate III. fig. 11 a, b.) Rhinolophus affinis (partim) Dobson, Cat. Cliir.
