This species apparently approaches the Ceylonese H. mononema, B. 
in character, but differs in its rounded base and less elevated spire. 
No. 7 . — Helix Todarum, n. s. PI. I. fig. 8. 
Testa perforata, suhdepressa, fulvo-cornea, tenuis, nitida striata ; 
spira depresso conica, apice acuta. Afr. 5 J sub-planulati, sensim aceres- 
centes, ultimus haud descendens, subtus convexus, radiato-striatulus. 
Apertura vix ohliqua, late lunaris : peristoma rectum, tenue, margine 
columellari breviter reflexo. 
Diam. major 14, min. 12. Alt. 8 mm. Apertura 6 mm. alta, 7 lata, 
vel „ 0.52 „ 0.48 „ 0.32 „ 0.24 „ 0.28 unc. 
Hah. prope Pykara et Neddiwuttom, in montibus Nilgiris. 
Near II. Perrotteti, Pfr. from which shell, however, the present 
appears to be distinguished by its higher spire and larger size. It, 
however, differs somewhat in measurement, and H. Perrotteti, also 
probably varies in size, as some specimens obtained upon the Nilgiris 
and apparently belonging to that species, measure, in their diameters, 
13 and 11 mm. and 7 in height. 
H. Perrotteti is also included in Messrs. King and Foote’s collec- 
tion, hut it is smaller than the type, and measures only 6 and 5 mm. 
in its diameters, axis 3 mm. 
No. 8 . — Helix mucosa, n. s. PI. I. fig. 9. PI. II. fig. 3. 
Testa imperforata, conoideo-globosa, tenuissima, pallide interdum 
subviride luteo-cornea, oblique striata ; spira breviter conoidea, apice 
acutiuscula, sutura marginata. Anfr. 4-5 convexiusculi, rapide accres- 
centes, ultimus major, non descendens, subtus convexus, ad peri- 
pheriam subeompressus. Apertura magna, ohliqua, late lunaris ; 
peristoma rectum, tenue, margine columellari brevissime appresso 
reflexo, perforationom claudente. 
Diam. maj. 9£, min. 8. Alt. 6 mm. Ap. 5 lata 4 alta. 
vel „ 0.38 „ 0.32 „ 0.24 „ 0.2 „ 0,16 unc. 
Habitat haud raro in montibus “ Nilgiris,” prope Pykara, ad 
Coonoor Ghat, et ad Seegoor Ghat. 
This shell appears to be allied to H. Acalles, Pfr. with which we 
have not met, but differs in the absence of both perforation and 
carination. It recalls somewhat in its general shape the Burmese 
H. honesta, Gould, from which, however, it is markedly distinct in size 
colour, sculpture, perforation, &c.
