P. violacea is a true Tanalia. The latter is not in Mi'. H. F. 

 Blanford's collection, and is apparently unknown to Messrs. 

 Bx'ot and Han ley.

This is most certainly not the P. parva, of Layard — long. 6 

 diam. 4 lines — from Bombay " with fine, spiral, brown lines," 

 which is most likely a var. of P. obesa, Philippi. 



The only ally, I know, of Pahidomus erronea is P. nigricans, 

 of which Mr. H. F. Blanford considers it a smooth variety ; the 

 above-quoted figure, however, shows the differences at a glance. 

 The operculum is that of Philopotamis. Long. 10^-, diam. 6h 

 mil. 



Apparently it is not figured by M. Brot ; the nearest seems 

 to be his pi. 6, fig. 14, " P. chilinoides, var. phasianinus.^' 



36. Paludomus [Philopotamis] subdentata. 



Paludomus subdentata, S. Nevill, MS.

Almost smooth, prettily longitudinally striped, *' flames " only 

 slightly flcxuous ; columella very broadly excavated, alabaster 

 white, subdontate at base ; spire truncate, two whorls only re- 

 maining, the last one convexly swollen ; flames are discernible 

 within the aperture.
