It is probable tliat these large western Pagumas should be 

 specifically separated from the smaller ones of Eastern and

 them all as subspecies of F. larvata.

 specimen, the type of the latter name, is still in the British 

 Museum, No. 81 a.

Arising out of the recent gift to the British Museum by 

 Prof. Wood Jones of some South-Australian Murida^, I have

 now find the three following forms to need description: —

Size, as gauged by skull and foot, decidedly larger than in
