Tanalia Tennentii, Reeve. 



Operculum the same as in the preceding species, but, if anything, 

 always more angular. 



Hub. as in T. Gardneri. 



Tanalia Reevei, Layard. 



Shell oblong ovate; axis 1 \ inch, diam. 1 in. 2 lines. Spire exserted, 

 short. Whorls rounded, spirally corded with rather distant obtuse 

 ridges, longitudinally striated with well-marked close-set strife, the 

 great characteristic mark of the species. Aperture : outer lip edged 

 with deep purple-brown, columellar lip white. Colour a dark yellow- 

 brown, thickly marked with longitudinal, slanting, jet-brown wavy 

 bands. 



Hab. The Calloo ganga, Katnapoora. 



I have much pleasure in dedicating this beautiful species to the 

 gentleman who has so extensively investigated this peculiar family. 



Tanalia violacea, Layard. 



Shell globose ; axis 6 lines, diam. .5 lines. Spire very short, 

 slightly exserted. Whorls rounded, ventricose, spirally grooved 

 with close-set, fine, minutely decussated striae (in one variety the 

 striae become ridges). Colour a dark bluish-brown, almost amounting 

 to black, with darkish brown patches appearing in some specimens. 

 Aperture deep violet inside ; columella white, stained on the outside 

 edge with dark brown. 



Hab. A small mountain torrent in a dense forest between Gilly- 

 malle and Pallabaddoola, towards Adam's Peak, Ceylon. 



Tanalia similis, Layard. 



Shell rather globose ; axis 8 lines, diam. G lines. Spire short, 

 exserted. Whorls rounded, ventricose, spirally grooved with close- 

 set, fine, minutely decussated striae. Colour rich olive-yellow, pro- 

 fusely marked with longitudinal, wavy, dark lines, interrupted by 

 four or five fine transverse bands of the same colour. Aperture : the 

 dark markings of the shell show through, and are dimmed by a bluish 

 haze ; columellar lip white, stained on the outside edge with dark 

 brown, which runs round the outer lip in a thin band. 



Hub. A mountain torrent at Kandangamoa, near llatnapoora. 



Tanalia funiculata. Reeve. 



I never could find any species which answered to Mr. Reeve's 

 description of this shell, until Mr. Cuming kindly lent me the type 

 specimen, when an hour's immersion in soap and water showed that 

 the "jet-brown" was merely the accumulation of the freshwater algae 

 (whicli always cover this sluggish family) and the red cabooky dust 

 of " Lidia's utmost isle." This cleaning revealed a bright yellow 

 epidermis, variegated with dark brown wavy lines, and the very 

 minutely striated structure of the shell ; and the specimen imme- 

 diately ranged itself with a series of a very variable shell, wliich I had 

 in vain endeavoured to reconcile with any published description.
