The above is the measurement of a very large specimen : in the 
majority the larger diameter does not exceed 8 to 8|- mm. 
Were it not for the characters of the animal, some doubt might 
arise as to whether this species should not be referred to Vitrina. 
The characters, however, of the mollusk are decidedly Helicoid, but 
peculiar. The posterior portion of the foot is long, tapering and 
abruptly truncated at the end, where it carries a mucus pore, partly 
covered above by a small projecting lobe. The colour of the body is 
greenish yellow, the edges of the foot being reddish brown, and the 
centre of the bark pure yellow. 
II. mucosa is tolerably common at the edges of sholas, and crawl- 
ing on the sides of stones in jungle, and was found in especial 
abundance at the side of the road leading down the Seegoor pass, 
where it is accompanied by Cyathopoma Jilocinctum, B. and Helix 
fasticjiata, Hutt. 
Mr. Foote has lately sent us a variety of this shell from the 
Ivalryen group of hills (to the East of the Shevroys), which differs 
from the Nilgiri specimens, in having a more distended mouth and 
somewhat more depressed whorls. It is figured at PL II. fig. 3 and 
its dimensions are as follow : — 
Height, 7 mm. 
Major diam 10 ditto. 
Minor „ 7.5 ditto. 
Height of aport 5 ditto.

Hab. rarissime prope Pykara montium Nilgiris. This shell in 
its form somewhat resembles a minute II. tapcina , Bens, with more 
rounded whorls, deeper sutures, and a non-expanded lip. 
* No figure is given of this shell, as the specimen forwarded by my brother 
for that purpose, was unfortunately crushed before it reached me. — H. F. B.
