1895.] H. H. Godwin-Austen— Notes on Indian Land Mollusca. 
Nevill suggests in Ms Hand List, that it “is probably closely allied 
to Stylodon (Stylodonta ?) possibly not separable.” This can only be 
settled after a comparative examination of the anatomy of the animals. 
It would certainly be a very interesting fact with regard to distribu¬ 
tion, to find a genus of the Seychelle Islands extending to Eastern India. 
I hope before long to receive specimens in spirit from the Khasi Hills. 
E. illustris Pfr. from Cambodia is very close to E. octlioplax , and Nevill 
includes bougainvillei , Pfr. from the Solomon Islands. Benson taking 
shell characters alone into consideration and, no doubt, thinking it one 
of the Zonitidde , placed it near cycloplax of Sikkim. 
It grows to a large size. My finest specimen measures, major 
diam. 61’0, minor diam. 5L’0, alt. axis 25’0 millim. 
Benson’s type measures, major diam. 46, minor diam. 26, alt. axis 
25-0 millim. 
Since commencing this paper I have received another and distinct 
species of this genus, from my old friend and former assistant in 
the Indian Survey Department, Colonel Woodthorpe, C.B., who got 
it on the eastern frontier of Burmah, beyond Fort Stedman ; and I am 
about to describe it in the Annals and Magazine of Natural History. 
It is preserved in spirit, so that I have been enabled to examine its 
anatomy. It appears to me far nearer to such forms of Gochlostyla as 
G. cineracea, Semper ; and if I should be correct in this view, it would 
be an interesting extension westward of that group of shells. 
Genus Plectopylis, Benson, Type achatina, Gray. 
Annals and Mag. Nat. Hist,, April I860.* 
This genus has been treated of by Mr. W. T. Blanford, in Annals and 
Mag. Nat. Hist., April 1861, and J. A. S. B., Yol. XXXIY, 1865, p. 73. 
In the P. Z. S., November 1874 and January 1875, and in this Journal 
for 1879, a number of species both old and new were described and 
figured with some detail by myself, especially as regards the very pecu¬ 
liar and characteristic internal plication. 
This genus is anatomically described most admirably by F. Sto- 
liczka from the type species, in this Journal for 187J, p. 217. How far 
it differs from Gorilla of Ceylon, to which it must be closely allied, has 
still to be made out ; as also the true affinity with retifera from the 
Nilgherries, and with clathratula from Ceylon, which is still more remote. 
Stoliczka, from his observation and knowledge of the animal, con¬ 
sidered this genus related to Glausilia. The genus is ovo-viviparous as 
observed in three species— achatina , cyclaspis and pinacis —jaw grooved,
