non-Marine Mollusca from South Africa. 195 



Ennea juxtidens, sp. n. (PI. III. fig. 2.) 



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

 fractibus 7-8, praecipue rectis, loevibus, interdum sub lente juxta 

 suturas obscure ct evanide obliquistriatulis ; apertura ovata ; 

 peristomate albo, crassiusculo, dentibus plicisve quatuor munito, 

 dente parietal! brevi, recto, labiali acuto, prominulo, basali 

 minuto ; plica columellari interna, inconspicua. 



Long. 4-50, lat. 2 mm. 



Hab. Van Rienen, Drakensberg Mountains {Mrs. Quehett). 



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. vaa- 

 staadensis is far more deep-seated and lirge. 



Many examples. 



Zincjis Haygarthi, sp. n. (Pi. III. fig. 3.) 



Z. testa crystallina, tenuissima, obscure perforata, superae 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 columellari circa umbilicum 

 minutum reflexo. 



Alt. 6'50, diam. 8 mm. 



Hah. 'Nkandhla Forest, Zululand [[laygarth). 



An unusually beautiful and delicate species, our exam[)le3 

 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. (PI. III. fig. 4.) 



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

 bus 5, tribus primis et basi nitentibus, Itevibus, ultimo magno, 

 eflfuso, baud nitente, sericato, sub lente spiraliter tenuissime 



♦ Inunctus, from the want of polish on the last whorl.
