P. violacea is a true Tanalia. The latter is not in Mr. H. F, 

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

 Brot and Han ley.

35. Paludomus [Philopotamis] erronea, nov. 



Con. Indica, pi. lOS, fig. 7, as P. parva '[}iof of Laiiard] ; ? P. phasia- 

 ninus, Layard, Ann. Mag. 1855, Ceylon [jiot of Reeve].

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. ohesa, PhiliiDj^i. 



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

 of which ]\ir. H. F. Blanford considers it a smooth variety ; the 

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

 The operculum is that of Fhilopotamis. Long. 10-J, diam. 6J 

 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, H. Nevill, MS. 



Resembles Brot's pi. II, fig. 2 [P. nigricans']. 



Almost smooth, prettily longitudinally striped, " flames " only 

 slightly flexuous ; columella very broadly excavated, alabaster 

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

 maining, the last one convexly swollen ; flames are discernible 

 ■within the aperture. 



Long. 13|, diam. 9f mil.
