104 Messrs. J. C. Melvill and J. H. Ponsoubj on

 same buiki as hullacea (Pfr.), but larger and in every way a 

 more striking species. 



Three specimens, in magnificent condition. 



The colour olivaceous horny, subpellucid in texture, in form 

 effuse and depressed, slightly conical towards the apex ; 

 whorls four in number, beautifully closely longitudinally lirate, 

 the lira3 giving a silky appearance to the whorls. Below, the 

 last whorl is quite smooth, olive-green, and very shining. The 

 umbilicus is narrowly profound, mouth lunar ; lip simple, 

 thin, slightly reflexed at the columellar margin. 



Discovered by Mr. Quekett, the active Curator of the

Hah. Transvaal [Mr. Botdcer). In Coll. Edgar L. Layard, 

 Esq. 



This shellj collected by Mr. Layard's nephew, Mr. Bowker, 

 in the Transvaal, is, though in damaged condition, so peculiar, 

 that we agree with its owner it is worthy of description. 

 Nothing we have seen in the National or other collections 

 exactly corresponds with it, though it does not at first sight 

 seem to possess any extraordinary characters excepting in 

 being sinistral. 



The shell is thin, ]Dale ochraceous, with longitudinal darker 

 brown flames; Avhorls seven, niicroscopically granato-striate, 

 the striae transverse, the last whorl appearing almost smooth, 

 though the above-mentioned striations are still Avith a lens 

 traceable for, at all events, some little distance below the 

 suture. Tiie wliorls are slightly ventricose, lip simple j 

 columella slightly contorted, fuscous, and strongly truncate. 



3. Acliatina j)enestes^ sp. n. (PI. III. fig. 3.) 



A. testa ovato-pyramidali, supra, et praesertim ad apicem, multum 

 attenuata ; anfractibus sex, sub leute grauato-decussatis, ad 

 sutiiras impressis, anfractu ultimo rapidc accrescente, ad basin 

 la^viorc, longitudinaliter irregulariter ruguloso ; apertura ovato- 

 oblonga, columella ad basin contorcjueiite, truucatula.
