Cleofatra emini. 



This pretty species is remarkable for the angulation and cari- 

 nation of the whorls. In five of the specimens at hand there are two 

 keels upon the whorls, whereof the upper and rather stronger one is 

 at the angle, the other being around the middle of the last volution 

 and revolving up the spire just above the sntural line. In one 

 example there is a third slight lira or keel upon the upper part of 

 the whorl between the suture and the angle ; and in another specimen 

 the peripherial carina has become obsolete upon the body-whorl and 

 is represented by a colour-band. C bulimoides, Olivier, if keeled 

 and angulated, would closely resemble this species. The operculum 

 in both species is the same. It is spiral at first with a raised edge, 

 and increases afterwards concentrically. 



Three specimens of this species have been liberally presented to 

 the Museum by the Rev. H. Waller. 



6. Bythinia alberti, n. sp. 



Testa parva, subglobosa, brevis, anguste umhilicata, alba, epidermide 



tenui lutescente induta ; anfractus A, perconvexi, lineis incrementi 



striati, ultimus haud elonyatus ; apertm'a submagna, fere ovalis, 



longit. totius \ paulo svperans ; peristoma continuum, leviter 



incrassatum, margine columellari anguste reflexo. Longit. 4 ; 



diam. maj.fere 4 millim. 



The chief distinguishing features of this little species are its short 



stumpy growth and the narrow umbilicus. Of the knowu African 



species, B. badiella, received by the British Museum from Parreyss 



with the locality " Egypt," is the nearest ally of the present form. 



It is, however, of a somewhat different shape, has a smaller aperture, 



and is more narrowly perforate. 



7. Bythinia walleri, n, sp. 



Testa parva, alhido-pellucida, nitida, perforata ; anfractus 4|-5, 

 perconvexi, striis incrementi tenuissimis sculpti ; apertura rotunde
