 Hcd). Lake Mweru (It. Crawsliay). 



This species is of the same character as Cleopatra emini, Smith 

 (P. Z.S. 1888, p. 54), from the Albert Nyanza. It is somewhat 

 larger, has less angular whorls, more keels or lirje, and a narrower 

 basal rimation. The longitudinal sculpture or lines of growth are 

 considerably more conspicuous. 



19. Melania tuberculata, Miiller. 



Hah. Angoni-Land (A. Wliyte). 



This species occurs in Tanganyika, Oukerevve, the Albert Nyanza, 

 and has previously been recorded from Nyasa. 



20. Melania nodicincta, Dohrn. 



Hab. Angoni-Land {A. Whyte). 



The single specimen which I assigii to this species is, in some 

 respects, intermediate between it and M. txdterculata. 



21. Melania turritospira, Smith. 



Tlab. Angojii-Land {A. Whyte). 



The specimen from this locality is twice as long as those figured 

 in these ' Proceedings' for 1877, pi. Ixxv. figs, 14, 15. Those figures 

 represent the surface too nodose. This species belongs to the so- 

 called genus Micronyassia of Bourguignat. 



22. Melania woodwardi. (Plate LIX. fig. 11.) 



Testa brevis, turrita, nigro-fusca, infra suturam pallidior ; 

 anfractus circiter 8, vise convexiu^ctdi, costis obliquis crassis 

 11-12 sulcisque transvcrsis angustis paucis (in cmfr. superioribus 

 2-3, in idtimo circiter 10) ornati, ultimus costis versus medium 

 sensim obsoletis ; apertura ovata, superne acuminata, lungit. 

 totius -!• p)aulo superans ; columella arcuata, alba., incrassafa, 

 rejte.va. 

 Longit. 19 millim., diam. 8; apertura 6g longa. 

 Hab. Lake Nyasa. 



The single specimen here described was presented to the 

 Museum by Mr. B. B. Woodward, after whom the species has 

 been named. It is quite distinct from any of the other Nyasa 

 forms. It is a short stumpy shell, of a very dark colour, with 

 oblique coarsely nodose ribs, the nodules being produced by the 

 spiral sulci cutting thi-oiigh the costtc.
