Nevill suggests in his 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. octhoplax, and Nevill 

 includes bougainvillei, Pfr. from the Solomon Islands. Benson taking 

 shell characters alone into consideration and, no doubt, thinking it one 

 of the Zonitidse, placed it near cyclopias of Sikkim. 



It grows to a large size. My finest specimen measures, major 

 diam. 61*0, minor diam. 51"0, alt. axis 250 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 

 C. 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., Vol. 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 veiw pecu- 

 liar and characteristic internal plication. 



This genus is anatomically described most admirably by P. 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.
