non-Marine Mollusca from South Africa. 195 



Ennea juxtidens, sp. n. (PL HI. fig. 2.) 



E. testa cylindrica, subperforata, nitente, apice obtusissimo ; an- 

 fractibus 7-8, praecipue rectis, Isevibus, interdum svib lente jiixta 

 suturas obscure et evanide obliquistriatulis ; apertura ovata ; 

 peristomate albo, crassiusculo, dentibus plicisve quatuor munito, 

 dente parietali brevi, recto, labiali acuto, prominulo, basali 

 minuto ; plica columellari interna, inconspicua. 



Long. 4-50, lat. 2 mm. 



Hah. Van Rienen, Drakensberg Mountains {Mrs. Quekett). 



This shining, smooth, subpel lucid species has for its near 

 allies both E. cionis and vanstaadensis, M. & P. From the 

 former it differs in being larger, in possessing less ventricose 

 whorls, in the simple labial tooth, and the inconspicuous 

 columellar plait. From the latter in the almost smooth and 

 glossy surface, in being smaller, and likewise not possessing 

 a bifid labial tooth; the columellar plait, too, of E. van- 

 staadensis is far more deep-seated and large. 



Many examples. 



Zingis Ilaygarthi^ sp. n. (PI. III. fig. 3.) 



Z. testa crystallina, tenuissima, obscure perforata, superne depresso- 

 conica ; anfractibus quatuor, undique spiraliter sub lente deli- 

 catissime striatis, supra, juxta suturas, castaneo-unizonatis, 

 anfractu ultimo magno, supra medium acuticarinato, infra rotun- 

 dato ; apertura circulari-lunata, intus pellucida, spiraliter uni- 

 zouata ; peristomate tenui, margine oolumellari circa umbilicum 

 minutum reflexo. 



Alt. 6*50, diam. 8 mm. 



Hah. 'Nkandhla Forest, Zululand {Hay garth). 



An unusually beautiful and delicate species, our exam[)les 

 being perhaps not quite adult. The last whorl is acutely 

 keeled above the middle, thence to the base semiglobose. 

 With the aid of a lens the surface is seen to be uniformly 

 closely spirally striate. 



Provisionally placed in Zingis till the anatomy is known. 

 We have much pleasure in dedicating so interesting a form 

 to its discoverer. 



Zingis inuncta*, sp. n. (PL III. fig. 4.) 



Z. testa magna, paullulum umbilicata, delicata, depressa ; anfracti- 

 bus 5, tribus primis eb basi nitentibus, l^vibus, ultimo magno, 

 effuso, haud nitente, sericato, sub lente spiraliter tenuissima 



* Jnundus, from the want of polish on the last whorl.
