MoUusca from South Africa. 133 



habit occurs in some geneva of the Zonitidse — such as 

 Microcystis, in myops and amhce for instance, — and in a dry 

 climate such as South Africa it would very likely be brought 

 about. 



Although dealing with a single specimen, scanty and poor 

 material to go by, there is enough to show it cannot remain 

 in Helicarion. The characters now described will be suffi- 

 cient to indicate it, and we must wait for further material to 

 clear up the doubtful points and what local forms in Sjuth 

 Africa approach it. 



ILslicarion vitalis, sp. n. (PI. VI [. fig. 4.) 



H. testa perteaui, vitrea, viride ochracea, rimata, globoso-conica ; 

 aufractibus 4|, apice ipso obtuso, cseteris ad suturas impressis, 

 ultimo rapido accrescente ; apertura rotundo-luuari ; peristomate 

 papyraceo, tenuissirao, apud regionem umbilicarem paullum 

 incrassato et reflexo. 



Alt. 12, diam. 15 mm. 



Ilab. Port Shepstone, Natal (Burnup). 



A very beautiful globose, transparent shell, tinted with 

 pale ochre, which seems distinct from all the species hitherto 

 enumerated from this region. 



Kaliella euconuloides, sp. n. (PI. VJI. figs. 5, 5 a, 5 b.) 



K. testa parva, anguste perforata, delicata, pellucida, cornea, 

 nitida, conica ; anfractibus ad 6. apicalibus obtusis, ceeteris 

 ventricosulis, ultimo apud peripheriam subangulato, basi convexa ; 

 apertura anguste lunari, peristomate tenui, 



Alt. 2' 19, diam. 2-.57 mm. 



Hub. Dargle, Natal {fJ, C. Bumup). 



A shining, snionth, horny, and glassy species, with very 

 small and narrowly perforated umbilicus, base convex and 

 brilliantly glossy ; the last whorl subangled at the periphery, 

 yome resemblance to Euconulus fulvus, Drap., a European 

 and British species, exists; but the general form approxi- 

 mates rather to Kaliella than Euconulus, conchologically 

 speaking only, the animal not having yet been examined, 

 though we hope shortly to be able to do so. 



AfkODONTA, genus novum Enddddntidaium. 



Ti'Hta parva, cornea, tenuis, late et profuiido umbilicata, depresso- 

 (.onica, vel plaiiorbula ; anfradus 4-5, apud suturas impresei, 

 vcntricosi ; apertura lumuis, fauce bi- vcl trihuucUata, lamella
