 Shackleford and Spence ; the rare Holospira cockerelli Dall from New Mexico,

 Melvill and Ponsonby; and Opeas micra D'Orb. , collected in gardens and 

 banana groves at Khartum, Sudan, by Mr. R. Cottam. It is probable that these 

 species have been introduced with non-indigenous plants, such as the banana, 

 otherwise they would be an important addition to the scanty land-shell fauna of 

 the Sudan.

 following species : Pisidium lilljeborgi, Llyn Cwm Clyd, Nant Ffrancon, Carnar-
