{Read before lite BomhaTj NoJural Historjj Society on 2Sth of Feb., 1899.) 



In llio Journ.'il of tlio Boinbii}'' Ntitaral History Society, Vol. XI, p. 

 131, is a very good account of (ho terrestrial Mollusca found in Bombay 

 Island by Mr. A. J. Poilo, II. A. The list given contaius all tlie 

 kinds known to occur in the island, and comprises the following 

 15 species : — 



Bnlifninus (Mastus) insuhiris. 

 B. abyssinicus var. nioussoni- 



anus. 

 B. (Rhachis) bengalensis. 

 B. (R) punctatus. 

 Stenogyra gracilis. 

 Glessula sp. 

 Suocinoa vitrea. 



Cyclophorus indicus. 



Ario[thanta Irovipes. 



A. bajadera. 



^'anina pelina. 



N. (Microcystina) temiicula. 



N.(M.) perrottoti. 



Helix (Trichochloritis) pro- 



pinqua. 

 Pupa (Leucochila) ca^nopicta. 



With one exception I believe the species are correctly identified, 

 though I cannot always concur in tho generic names. But genera 

 among Pulmoniferous Mollusca are, and aro likely to remain for a long 

 time to come, either guesses (when the animal has not been criticnliy 

 examined) or else mere expressions of i), dividual views. Species are 

 far more definite, at all events when those of one locality come under 

 consideration. The particular species as to the name of wdiich I would 

 suggest further consideration is that Avhicli Mr. Peile (p. lo4) identi- 

 fies as Naniiid [Microci/stina) peri'oUetu 1 am well acquainted with the 

 Bombay Mollusk, which is pretty common (or was some thirty years 

 ago) on Malabar Hill, and which attracted my attention by having, 

 instead of the pointed, narrow shell-lobes (or as Mr. Peile very a})tly 

 crills them shell-polishing lobes) of Macroclilamr/s, (the genus to m hich 

 I refer both M. ^v^^ma and M. tenuicula, although neither is a typical 

 form) broad spatulate lobes which, in the height of the monsoon, when 

 the mantle and its lobes are fully developed, completely cover the 

 shell. 



The name i/^-Z/a-^jen-of/lC'/;? was applied by Pleiifer to a species inha- 

 biting the Nilgiri Hills. It was described as " spim brevissime subturb-
