Balea africana^ sp. n. (PI. III. fig. 10.) 



B. testa sinistrorsa, fusiformi, baud profunde perforata, teaui, 

 nitida, olivaceo-brunnea ; anfractibus 7, apicali obtuso, cseteris 

 apud suturas impressis, tumidulis, undique longitudinaliter 

 ruguloso-striatis ; apertura ovata ; peristomate continuo, pauUuta 

 incrassato, margin e columellari intus indistincte et obtuse uni- 

 plicato, crassiusculo. 



Long. 6, lat. 1-75 mm. 



Hah. Van Rienen, Drakensberg Mountains {Qaekett). 



Another most interesting addition, generically, to the 

 South-African fauna. From the few other Balece known 

 to us this would seem to differ mostly in the shorter and less 

 acuminate spire, more compressed growth, and in the very- 

 obscure character of the obtuse columellar fold. We should 

 consider it a member of the typical section of the genus, with 

 the European B. perversa, h.,=/ragih's, Fitz. 



Pupa crypioplax "^ , sp. n. (PI. Til. figs. 11, 11 a.) 



F. testa conico-pyramidata, valde et profunde perforata, tenui, 

 olivaceo-brunnea, apice obtusissimo, planato ; anfractibus 8, apud 

 suturas impressis, undique sub lente obliquistriatis ; apertura 

 obliqua ; peristomate fere continuo, albo, nitente, reflexo ; plica 

 parietali magna, acinaciformi, columellari perintrante, con- 

 spicua, acuta, intus duplicata ; dente labiali parvo, albo, obtuso. 



Long, 3*50, lat. 2 mm. 



Hah. Kragga Kanma, Port Elizabeth. 



One of the most abnormal of the genus, and perhaps 

 worthy of special subgeneric rank. We figure an example 

 broken away (fig. 11 a) so as to show the duplicated internal 

 columellar fold. 



Curvella sinuosa, sp. n. (PI. III. fig. 12.) 



C. testa fusiformi, nitida, tenui, pallide et laete straminea ; anfracti- 

 bus (incluso apice papillari, obtuso, Isevissimo) 7, apud suturas 

 impressis, fere laevibus, sub lente longitudinaliter flexuoso- 

 striatulis ; apertura ovata ; peristomate sinuato, simplici, margine 

 columellari recto. 



Long. 6-50, lat. 3 mm. 



Hah. Umkomaas, Natal. 



An elongate fusiform Curvella, quite distinct from the two 

 other recently described species {catarractce and globosa, 



* K/juTrroTrXa^, with hidden plic89.
