 Kempia subgen. n. 



Differing from typical Pseudoglessitla in the columella which is ?iot trun- 

 cate^ but continuous with the labrum, tlirough stharply, obliquely curved 

 below and in lacking the peripheral carina of that genus. 



Genot5fpe. K. kiviiejisis. 



The above subgenus would appear in some respects to form a 

 link between Pseadoglessula and Limicolaria, but I incline to 

 place it as a subgenus of the former, rather than to raise it to the 

 rank of a genus intermediate between the two. 



Kempia kivuensis sp. — PI IV, fig. 3. 



Shell C3'lindrically fusiform, moderateh^ solid, shining, reddish brown ; 

 whorls 7, the first- minute, the second and third large in proportion, the 

 remainder regularly increasing, the last rather long, the apical whorls 

 coarsel}', distantly and somewhat obliquely, transversely costulate, the 

 remainder fînel}', closely and rather obliquely so, the costulae becoming 

 subobsolete on the lower portion of the last whorls; suture impressed, 

 narrowly and indistinctl}^ margined below; columella tinged with livid- 

 lilac, slightly obliquely descending above and very obliquely below, 

 diffused above into a very light, well defined, granular, pariétal callus 

 which reaches the upper margin of the labrum ; labrum simple, not ver}^ 

 acute, dilated at the base, bent ver)'' slightlj' inwards over the aperture 

 above; aperture rather elongateh^, inverseh' auriform; interior of shell pale 

 bluish-lilac.

Kempia burungaensis sp. n. — PI. VI, fig. 2.
