obtains in the var. breviplica of that species. The specimen 

 figured, which I received from the late Miss Linter, was labelled 

 with the habitat, '* Moulmain." It measures : major diam. 16, 

 minor 13 mm. ; alt. 6 mm. Another shell from the same source 

 measures 12'25, 10-5, and 5 mm. respectively.

Differs from the type in being unicolorous dark brown, a little 

 paler below, in being thinner in texture, and in the peristome 

 being livid.

Hab. Burma. 



A shell in Mr. Ponsonby's collection, which was labelled 

 P. pacliy 'stoma, var. minor, I was unable to separate specifically 

 from P. linterce. It differs, however, from the typical form of

that species in being of a unicolorous dark brown, in the peri- 

 stome being livid instead of white, and in the shell being thinner 

 in texture. The armatures are identical in both forms. Fig. 68 d 

 shows the parietal wall with its folds, while fig. 68 e gives the 

 anterior, and fig. 68/the posterior aspect of both sets of barriers 

 (enlarged). Figs. 68 a-c show the entire shell (natural size). 



Four specimens from the Attaran Valley, in the Theobald 

 collection, British Museum, agree with Mr. Ponsonby's shell, 

 except in size, measuring 16 mm. in diameter.
