Tan ALIA Tennentii, Reeve. 



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

 always more angular. 

 Hab. as in T. Gardneri. 



Tanalia Reevei, Layard. 



Shell oblong ovate; axis 1 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 striae, 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, Ratnapoora. 



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. 6 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. 



Hab. A mountain torrent at Kandangamoa, near Ratnapoora. 



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 

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

 of "India'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, which I had 

 in vain endeavoured to reconcile with any published description.
