Heller * treats all the forms in the rufescens group with 

 the large chest-gland as subspecies o^ 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 ray view, to rank as a 

 species.

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