(58) Leptachatina semicostata Pfeiffer. 



Achafinella {Leptachatina) semicostata Pfeiffer, P. Zool. Soc. London, 1855 [1856, 

 Feb.], p. 206. 



Dr Hartman remarks (P. Ac. Philacl. 1888, p. 55) " Dr Newcomb thinks it 

 questionable if this species be not a synonym oi L. fusca Newc." ; it is quite distinct. 

 Hab. Hawaiian Islands (Pfeiffer). 



(59) Leptachatina semipicta Sykes. 



Leptachatina semipicta Sykes, P. Malac. Soc. London, 11. (1896), p. 128. 



Plate XL fig. 12. 



Hab. Lanai, Mts. behind Koele (Perkins). 



(60) Leptachatina simplex- Pease. 



Leptachatina simplex Pease, P. Zool. Soc. London, 1869, p. 651 (nom. sol.); 

 J. Conchyl. xvii. 1S69, p. 170. 



Dr Hartman notes (P. Ac. Philad. 1888, p. 55) that "Examples L. nitida Newc. 

 (coll. Newc.) and L. simplex Pse. (coll. Pse.) are similar." There must be some error 

 here, as specimens presented by Pease to the British Museum are quite distinct from 

 L. nitida Newc. ; further, Newcomb's species does not come from Hawaii. 



Hab. Hawaii (Pease) ; Kona, at 3000 — 4000 feet (Perkins).
