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



B. testa sinistrorsa, fusiformi, haud profunde perforata, tenui, 

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

 apud suturas impressis, tumidulis, undique longitudinaliter 

 ruguloso-striatis ; apertura ovata ; peristomate continuo, paulluin 

 incrassato, margine columellari iutus indistincte et obtuse uni- 

 plicato, crassiusculo. 



Long. 6, lat. 1-75 mm. 



Hah. Van Rienen, Drakensberg Mountains [Quekett). 



Another most interesting addition, generically, to the 

 South-African fauna. From the few other Balece known 

 to us this would seem to diflfer 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 thf. geiiu>, with 

 the European B. perversa ^ L.,=}'ragih'sj Fitz. 



Pupa cryptoplax^j sp. n. (PI. III. figs. 11, 11 a.) 



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

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

 suturas impressis, undique sub lente obliquistriatis ; apertura 

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

 parietali magna, acinaciformi, columellari perintrante, con- 

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



Long. 3-o0, lat. 2 mm. 



llah. 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 simiona, sp. n. (PI. III. fig. 12.) 



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

 bus (incluso apice papillari, obtuso, laevissimo) 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. 



JJab. Umkomaas, Natal. 



An elongate fusiform Curvella, quite distinct from the two 

 other recently described species {catarractcB and globosa^ 



* KpvTtTonXa^, with hidden plicae.
