300 MELANIIDE. 
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 Hanley.

2 “ Kandapanne Ella, 4 Corles,”’ Ceylon ; coll. F, Layard, Esq. 
Sent to me as Paludomus, n. sp. 
2 Hackgalle, Ceylon [with opercula] ; coll. H. F. Blanford, Esq. [labelled 
“ T, violacea’’]. 
35. Paludomus [Philopotamis] erronea, nov. 
Con. Indica, pl. 108, fig.7, as P. parva [not of Layard]; ? P. phasia- 
ninus, Layard, Ann, Mag, 1855, Ceylon [not of Reeve]. 
6 Hackgalle, Ceylon [at 5,500 ft.]; exc. As. Soc. Bengal [coll. E. L. 
Layard, Esq.}.

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 Paludomus 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. 64 
mil, 
Apparently it is not figured by M. Brot; the nearest seems 
to be his pl. 6, fig. 14, “ P. chilinoides, var. phasianinus.” 
36. Paludomus [Philopotamis] subdentata. 
Paludomus subdentata, H. Nevill, MS. 
Resembles Brot’s pl. 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, 133, diam. 9$ mil.
