or 0. spiniila, Morelot, which nearly approaches it in form. 

 While very near the border-line between Opeas and Curvella, 

 I consider'tlie comparative slenderness of its contour sufficient 

 reason for placing the present species in Opeas. 



Genus Curvella, Cliaper, 1885. 



(Bull. .Soc. Zool. de France, x. pp. 48, 49.) 

 {=Hapalus, Albers, 1850, non Jlapalus, Billberg, 1820.) 



Small shells, so named because of the forward curve of the 

 outer lip. Very near Opens, from whicli they are generally 

 chiffly separable by their shorter wider contour and smaller 

 number of whorls.

Hab. Natal, Howlck, Pietermaritzburg, Stella Bush 

 [Burnnp) ; Durban [Penther, fid. Stiwany). 



A .rather characteiL ss little shell with obtuse apex and 

 rather ventricose body-whorl. The largest specimen in Coll. 

 Bnrnup measures 6*5 x 3"o mm. Like others of the genu.'?, 

 this species has a partiality for living in ants' nests, where 

 ]\Ir. Burnup informs me he has more than once found them. 



2. CurveVa globosa (Melv. & Pons.).

 pi. viii. fig. 31. 



IJah. Natal, Stella Bush (Buniup) . Cape Colony, York, 

 Drakensberg, Griqualand East [Farquhar). 



A small shell, whose whorls, especially the last, are more 

 swollen in comparison than those of any of its allies. With 

 this exception, however, it bears a marked resemblance to 

 the preceding species. 



3. Curvella sinuosd, Melv. & Pons. 



1899. Curvella sinuosa, M. & P Ann. & -Mag. Nat. Hist. iv. p. 198, 

 pi. iii. fig. 12.
