NOTES ON THE SPECIES OF ENNEA AND LEPTO- 

 POMA RECORDED FROM CEYLON, WITH DESCRIP- 

 TIONS OF SOME NEW LAND-SHELLS FROM THAT 

 ISLAND. 



By E. R. SVKES, B.A., F.Z.S. 



(Plate II.) 



The only two forms of Ennea recorded from Ceylon are E. bicolor 

 (Hutton) and E. ceyla7iica (Pfr.). These are, I think, one and the 

 same species, for which the former name has precedence. The 

 species was collected at Galle and Trincomalie by Mr. Preston ; at 

 the latter locality he also found a single specimen which I was unable 

 for some time to identify. Mr. Blanford kindly examined it and 

 suggested that it might be a form of E. sie?wsfoffia (Bedd. MS.) 

 Blfd., described from Madras. I have compared the single shell with 

 the specimens of that species in the British Museum, and except 

 for the Ceylon specimen being a trifle larger, I am unable to arrive 

 at any distinguishing characteristic.^ 



Leptopoma. 



The species already recorded from Ceylon, belonging to the 

 Leptopoma group are the following : — • 



Leptopoma elatum (Pfr.). 



Cyclostovia elatum, Pfr.: Proc. Zool. Soc, 1852 [1854], p. 159; 

 Conch. Cab., 1853, Cyclostomacea, p. 246, pi. xxxii, figs. t6, 



17- 

 Leptopoma elatum, Pfr. : Mon. Pneum. Viv., 1852 [? 1853], p. 117; 



Reeve, Conch. Icon., Leptopoma, sp. 3; Hanley and Theobald, 

 Conch. Ind., pi. cxlii, fig. 2. 

 Hab. — Ceylon. 



Only known to me from the original series in the British Museum : 

 it is a somewhat carinate shell, of a " Philippine form," belonging to 

 the group of L. atricapillum, Sby., and Z. regulare, Pfr. 



Leptopoma semiclausum (Pfr.). 



Cyclostoma (^Leptopoma) semidausutn, Pfr. : Prof. Zool. Soc, 1854 

 [1855], p. 302. 



I Since the above was written, Mr. Blanford has informed me that E. stcnostoma is probably 

 identical with Pupa plang^tncula of Benson.
