]94: Messrs. J. C. Melvill and J . H. Ponsonby on 



The term Avstroci/clus, proposed by Aucey {loc.ctt.) to receive Cycloph. 

 Wahlbeigi, can only be regarded as a synonym of Hijahia, Godw.-Aust., 

 published in Jan. 1898, while Antey's "paper is dated June of the same 

 year.

 This species has been found in Ashanti, but we have not met with it 

 at present from South Africa.

Trachycysfis charybdis, Bens. — Thanks to the kindness of the Kev. A. H. 

 Cooke, we have been able to iuspect the type of Benson's hitherto un- 

 figured ''Helix" charybdis iu tlie Cambridge Museum. It is, unfortunately, 

 a good deal damaged, so we have thought it best to give a figure of a 

 specimen t from our collection, which appears to enrref-poud in everyway 

 with the type, except that the latter is a trifle smaller. Our specimen came 

 from the neighbourhood of Cape Town.

A minute glassy species, of which we liave seen four 

 examples. Its mouth-processes consist of a large, deep- 

 seated, sharp parietal j)lait, a double labial tooth, the lower 

 projection of which is maniillate and internal, a small acute 

 basal toolh, and below the thickened coluuiellar margin a 

 very deep-seated extensive ])lait, half closing the aperture. 

 We should consider E. Farquhari, M. & P., a near ally of 

 this species, equally minute, similarly subpellucid, and deli- 

 cately longitudinally striate, and also furnished with four 

 mouth-processes, of which the parietal and labial plaits and 

 leelh are not vo-y dissimilar, the labial tooth being bifid in 

 both species; the columellar margin is, however, much more 

 pronounced in /:-'. viicrot/umnut, almost as much so as in 

 E. luhj^ruitluo, M. & P.
