SYKES : SPECIES OF ENNEA AND LEPTOPOMA. 27 



Leptopoma semiclaiisum, Pfr. : Reeve, Conch. Icon., Leptopovia. 



sp. 35 ; Hanley and Theobald, Conch. Ind., pi. vi, fig. 2. 

 Hab. — Ceylon (Thwaites). 



Leptopoma apicatum, Benson. 



Leptopoma apicatum, Bens. : Ann. Nat. Hist., 1856, (2) xviii, p. 95 ; 

 Reeve, Conch. Icon., Leptopojua, sp. 33 ; Hanley and Theo- 

 bald, Conch. Ind., pi. cxlii, fig. i. 

 Hab. — Ceylon (Layard). 



The single specimen in the British Museum, apparently correctly 

 identified, and figured as above mentioned, is a very dead shell : it 

 may possibly prove to be only a form of the last species. 



Leptopoma (Leptopomatoides) halophilum (Bens.). 



Cyclostoma halophilum, Bens.: Ann. Nat. Hist., 185 1, (2) vii, p. 

 265 ; Pfeiffer, Conch. Cab., Cyclostomacea, p. 241, pi. xxxi, 

 figs. 29—31. 

 Leptopoma halophilum, Bens. : Reeve, Conch. Icon., Leptopoma, 



sp. 49 ; Henley and Theobald, Conch. Ind., pi. vi, fig. 3. 

 Hab. — Galle (Benson); Colombo (Templeton); Maturata (Jous- 

 seaume) ; Galle, Colombo, Trincomalie, Ratnapura at 1000 

 feet (Preston). 



A single specimen, kindly lent me by Col. Beddome, which I am 

 unable to separate from this species, was found " on Pedro." 



I have elsewhere^ dealt with the history of the subgenus Leptopo- 

 matoides : since writing I have discovered that Prof, von Martens" 

 appears to have been the author who first put the name forward as a 

 subgenus and therefore it should stand as Leptopomatoides, Martens. 

 It may prove useful as a name for this compact little Ceylon group, 

 and appears to also include a few outlying species from China, etc. 



Leptopoma (Leptopomatoides) orophilum (Bens.). 



Cyclostoma orophilum, Bens. : Ann. Nat. Hist., 1853, (2) xi, p.
