in wliich tlicre is a small extra tubercle just above tlie tooth 

 on the outer lip. G. dujjuisi bears close i"eseiublauee to 

 G. vwnodon (Morelet) { = cunica, !Mts.) and G. munodun 

 zariuensis (Frestou), but these have no dental process on 

 the cohunella and a snwdl tubercle, rather than a tooth, ou 

 the inflexion of the outer lip. G. po/luneriana, Pilsbry, and 

 the other members of its j^roup differ clearly by the presence 

 of an angular parietal lamella and more pronounced colu- 

 mellar dentition. 



I have much pleasure in dedicating the new species to its 

 finder, Major Paul Dupuis, the pioneer of our recently 

 extended knowledge of Congo luoUusca. The type is in his 

 collection. 



Section Pupiqulella, Pilsbry, 1919. 



Gulellu (Pupiffulella) pupa (Thiele) and 

 Gulellu {Pupiytilella) jjupa ituritnsis, Pilsbry. 



A new and unexpected locality for both the above is 

 Camerun, Bitze {Bates). 



Of two sliells from Bitze now before me, the smaller 

 seems to agree with Tliiele's figure of G.pupain all respects 

 except the aperture, which is less oljlique, and in its rather 

 smaller dinu-nsions, -I'S X 2*G mm. with half a whorl less tliau 

 the figured example from Butumbi, Belgian Congo. 



I am quite unable to separate the lai-ger shell from Bitze 

 from Pilsbry's description and figure of his subspecies 

 ituriensis ; it agrees in length, 5^ mm., and number of 

 whorls with the quoted dimensions of a specimen from 

 Medje. 



My two shells differ noticeably in sculpture, which may 

 be described as ordinary and regular, though closer on the 

 last than on the penultimate whorl, in the typical form, 

 while in ituriensis it is coarser and more oblique on the 3rd 

 and 4th, and almost obsolete on the front of tlie last whorl, 

 except for showing very strongly near the erenulate suture. 



If my identification of the two forms is correct, and the 

 difference in sculpture is constant, it should be quite 

 sufficient to establish them as distinct species.
