spire being conically depressed, mouth large, lip very thin 

 and fragile. 



Three specimens in Mr. Layard's collection. 



2. Natalina coerneyensis, sp. n. (PI. I. fig. 2.) 



N. testa anguste umbilicata, conica, cornea, nitente ; anfractibus

Hah. Coerney, near Port Elizabeth [J. Crawford). 



A comparatively large and handsome species, near N. knys- 

 ndensis (Pfr.), but the upper whorls are strongly striate, 

 while the umbilicus in the latter species is much more nar- 

 rowed by the triangularly reflexed growth of the columella. 



We have also seen a good series of this shell in Mr. Layard's 

 collection, labelled " Natal." 



'6. Natalina Chaplini, sp. n. (PI. I. fig. 3.) 



N. testa depressiuscula, late et profunde umbilicata, ad apicem 

 planata; anfractibus quatuor, supra oblique lougitudinaliter dense 

 striatis, ultimo infra nitido ; apertura ovato-luuari; peristomate 

 tenui, simplici. 



Long. 6, lat. 10-50 mill. 



Hob. Karnachs, near Port Elizabeth [J. Crawford) . 



A very pretty species, of the same section as vernicosa &c, 

 and of a beautiful golden horny colour, striated above, shining 

 beneath, widely umbilicated, and much depressed. 



Three specimens, which, although perhaps not quite full- 

 grown, seem to present distinct specific characteristics. 



4. Helix (Dorcasia) inhluzana, sp. n. (PI. I. fig. 4.) 



II. testa profunde sed auguste umbilicata, oblique depressa, cornea 

 nitida ; anfractibus quatuor, longitudinaliter striatulis, apud 

 suturas compressis, ultimo subdepresso, antice deflexo ; apertura 

 oblique ovata ; peristomate simplici, ad umbilicum paullum 

 reflexo. 



Long. 15, lat. 23 mill. 



Hab. Inhluzan Mountain, Drakensberg Range (Mrs. C. 

 Shaw, per J. F. Quekett). 



Two specimens of a conspicuous shining horny shell, allied 

 toll. Kraussii (Pfr.), from which species it differs in being 

 more compressed laterally and not so much at the base round
