 Hob. Lake Mweru {E. Ci-awsJiay). 



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 Mhorls, more keels or lirfe, aud a narrower 

 basal rimation. The longitudinal sculpture or hnes of growth are 

 considerably more conspicuous. 



19. INIelaxia tuberculata, Miiller. 



Hah. Angoni-Land (A. Wh/te). 



This species occurs in Tanganyika, Oukerewe, the Albert Nj'anza, 

 and has previously been recorded from Nyasa. 



20. Melahta nodicincta, Dohrn. 



Hab. Angoni-Land (A. Whjte). 



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

 respects, intermediate between it and M. tuberculata, 



21. Melania turritospira, Smith. 



Hah. Angoni-Land (A. Whyte). 



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

 in these ' Proceedings' for 1S77, pi. Ixxv. figs. 14, 15. Those figures 

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

 called genus Mieronyassia of Bourguignat. 



22. Melakta avoodwaedi. (Plate LIX. fig. 11.) 



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

 Hcd). Lake Nyasa. 



The single specimen here described \\as 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 ISTyasa 

 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 through the costoe.
