transversely striate, and this is also the case round the 

 umbilical region, the strijB towards the middle of the last 

 ^vhorl soon ceasing; the mouth is thin, simple; aperture 

 rotund-ovate, columellar axis slightly thickened, white. 

 iSeveral specimens. 



Ihlix [Trachycystis) Alcocki, sp. n. (PI. XII. figs. 2, 2a.) 



//, testa anguste umbilicata, depresso-conica, apico mammillato, ad 

 peripheriam obtusangulata ; anfractibus sex, veutricosulis, uadique 

 transversim tenui-striatis, striis sericeis, longitudinaliter epider- 

 mide evanida contectis, oblique costulatis, ultimo, apud periphe- 

 riam praicipue, setiforo ; apertura lunata, compressa ; peristomate 

 tenui, simplici, apud marginem columellarem pauUum rellexo.

Several specimens of a little shell apparently distinct from 

 its allies. In the setose epidermis it resembles H. tricho- 

 steiroma^ M. & P., and is also near U. Loveni (Kr.), but is more 

 depressed than that species. 



Achatina Churchilliana, sp. n. (PI. XII. fig. 3.) 



A. testa pyramidato-fusiformi, solidiuscula, apud apicem obtusa ; 

 anfractibus septem, tumidulis, ad suturas subimpressis, supra, 

 apud suturas, indistincte granato-striatis, infra applanatis, laevibus, 

 epidermide tenui cinereo-ochracea tectis, anfractu ultimo pro- 

 duct© ; apertura oblonga ; peristomate simplici. 



Long. 3, lat. 1-50 unc. 



Hah. Natal [G. C. Churchil\Esq.). 



This plain-looking Achatina is doubtless one of the natal- 

 ensis group, but we cannot identify it with any of the hitherto 

 described species. The limits of variation in this genus have 

 not, so far, been studied, and the local forms merit more 

 attention than they have yet received. The label attached to 

 the specimen, now unique, in the Owens College Museum, Man- 

 chester, is as follows : — " Bulimus. G. C. Churchill, Esq. 

 Port Natal." 



We have much pleasure in connecting with this shell the 

 name of our friend Mr. Churchill, of Clifton, Bristol, so well 

 known in botanical and other scientific circles. 



Cyclostoma foveolatum^ sp. n. (PL XII. figs. 4, 4 a.) 



C. testa anguste sed profunde umbilicata, effuso-pyramidata, cinerea ;
