Mr. Benson describes this species as being covered with 

 a very minutely wrinkled epidermis. 



Species 751. (Mas. Benson.) 



Helix cestus. UeJ. tesld anguiti umbiUcatd, subco- 

 noidfd, creberrime oblige pUcatostriatd, fuicescetite, 

 fnmd anguita nifd supra peripheriam citigulatd ; an-

 tegente. 



The girdle Helix. Shell narrowly imibilicated, subco- 

 noid, verj- closely obliquely plicatelv striated, brownish, 

 encircled above the periphery with a narrow red band; 

 whorls five, flatly convex, last whorl obtusely angled ; 

 aperture obliquely ovate ; lip tliin, reflected, columel-

Hob. Xilgherry Mountains ; Jerdon. 



An authentic specimen of this species enables me to cor- 

 rect an error, copied from Dr. PfeilTer, in quoting it as a 

 variety of //. similam (PI. XXXFW fig. 149). It is of a 

 more angular obliquely convoluted form and altogether 

 diiferent.

Tue Rui'Guisii Helix. Shell umbilicated, depressed, 

 faintly roughened throughout with minute grains, 

 dull white, variously encircled with red lines ; spin- 

 but little raised ; whorls four, rather flat, the last 

 convex at the base, descending but little in front,
