topotypes for purposes of comparison). Though the body dimensions 

 appear to be a little larger the cranial measurements and external 

 appearance of the adult female are practically those of the type. 

 Tlie convergence on the neck and crown of the black dorsal stripes 

 is particulai-ly notable in both examples.

This form exhibits close relationship with T. helangeri of 

 Tenasserim and more northern areas, while such examples of the 

 Bandon animal as have been collected show, as we have pointed out 

 elsewhere, less differentiation form T. ferruginea of the southern 

 portion of the Peninsula, as far as colour is concerned, than does 

 F. f. wilhinsoni wliich occurs on the west coast between the latitudes 

 of the above-mentioned places.

Differ from T. f. operosa in the possession of dullei* pelage and 

 shorter rostrum and thus, still more than that race, approaches the 

 continental species T. belangeri.
