The tied Helix. Shell narrowly umbilicated, depressly 

 globose, longitudinally striated at the upper part, 

 minutely decussated, smooth beneath, white, en- 

 circled by a single rather broad yellowish band 

 above the periphery ; whorls five, rather flattened, 

 last whorl convex at the base ; aperture irregularly 

 luiiar-elliptical ; lip simple, right margin straight, 

 columellar margin somewhat reflected, forming an 

 obsolete angle with the basal margin.

Bab. Bengal. 



The broad yellowish band, which is a characteristic 

 feature of this species, rests, so to speak, upon the suture, 

 and is darker in colour as it approaches the apex. 



Species 396. (ilus. Cuming.) 



Helix Javaxica. Hel. testa umbilicatd, orbiculato-con- 

 vexd, superne con/ertim costulato-slriatd, basi subla- 

 vi{/atd, liUescente-corned, fasciii anguslis rujis zonaid,

 aperturd subanguloto-lunari; perislomate simplici, recto, 

 margine columellari ad umbilicum percium breviter di- 

 latato, rejlexiusculo. 



The Java Helix. Shell umbilicated, orbicularly convex, 

 closely rib-like striated at the upper part, rather 

 smooth at the base, yellowish-horny, zoned with 

 three narrow red bands, two near the periphery and 

 the tliird at the suture ; spire short ; whorls sLx, 

 rather flat, the last slightly keeled, keel vanishing in 

 front ; umbilical area red ; aperture rather angularly 

 lunar ; lip sunple, straight, columellar margin shortly 

 dilated and somewhat reflected at the umbilicus, 

 which is open.

Helix Jacanensis, Ferussac. 

 Hai. Java. 



Of the two central bands which characterize this species, 

 one is immediately above the keel and one below it. The 

 area of the umbilicus is particularly dark-criloured.

The left-ua*\ded Helix. Shell umbilicated, sinistral 

 nearly orbicular, somewhat depressed, rather thin, 

 slightly keeled, decussated beneath the lens with dis- 

 tinct stria; of growth and a few spiral lines, whitish, 

 encircled with three red-brown bands ; wborb four 

 to five, rather flattish ; aperture somewhat ■'mail, 

 rather oblique, lunar ; lip simple, acute, columelUr 

 margin a little reflected.

The two central bands of this species, which is always 

 reversed, are broader and wider apart than in the pre- 

 ceding.
