J/ab. Zwelleiulam, Cape Colony (R. M. Lightfoot). 



W itiiout any very tangiljle cliaracters, tlii.s eoinpactly 

 fonncd 2\\itnlina seems perfectly distinct from any other 

 member ot tlie genus. It may to sonio recall, of course only 

 8Uj)erHeially, certain Australian species of tlie^enus Badistes. 



We liavo much pleasure in connecting with this interesting 

 niollusk the name of Mr. Lightfoot, of the Soutli African 

 Museum, Ca{)eto\vn, by whom it was collected.

Hall. Warmbatli, Pretoria, Transvaal {ConnoUg^ who 

 jossesses a good series of the s|)ecies). 



A dark dun-coloured Zingis, to some extent comparable 

 with Z. arnolli, Bens., also from South Atriea (fig. 16), from 

 which it ditiers in several particulars, such as colour and 

 texture, being a thicker and browner shell, with aperture also 

 narrower, atid more distinct umbilicus. The spire, too, is more 

 conically depressed and the whorls narrower proportionally.

 prove not to belong to Trachgcgsds.
