Shell and dorsal lobes as in typical MacroMamys, the right shell- 

 lobe being long and pointed and the left a small tongue-like 

 process. The generative organs were not well preserved, but the 

 amatorial organ was present and the other organs of usual form, 

 the coiled caecum of the penis being small. 



The species was also obtained at Teria Ghat, two examples ; 

 from the Lhota Naga Hills, one ; and from Pikuui in the Lahupa 

 Naga Hills, tuo. 



The preceding eight species are very closely allied and similar 

 in shell-character. The living animals require examination, and 

 far better material for dissection is required than I had to deal 

 with.

Locality. Thyetmyo, Pegu {Theobald, or Blanford). Indian 

 Museum,' Calcutta, No. 3676 c. 



This shell is one of the ten recorded in Nevill's Hand-list, i. (1 878) 

 No. 43, p. 24, as Manina (Macrochlamys) honesta, Gould. There 

 were three species in the same tube, respectively J/, chaos, 

 W. T. Bit., 7 specimens ; M. Jidus, n. sp., 2 specimens ; and the 

 one under review, a very distinguishable form.
