Heller * treats all the forms in the rufescens group with 

 the large chest-gland as subspecies of rufescens. The external 

 characters of ocularis — notably the large and conspicuous 

 white markings about the eye — and the large bare patch in 

 the sacral region fully entitle it, in my view, to rank as a 

 species. 



Taterona swaythlingi, sp. n. 



A long-tailed species, with small dark tail-tuft and small

 of the vicina type, i. e., black or very dark brown on the 

 upper surface through its entire length, with a small tuft at 

 the extremit3\ Under surface fawn-coloured, generally 

 without trace of white hairs, though these are present in one 

 or two specimens examined. Under surface and feet white.
