As neither the original figure of E. maria^ nor that published with the description of "E. callista" is di-awn in true proportion, or expi"esses clearly the characters of the species, I take this opportunity of publishing a new figure. For this purpose I have been fortunate enough to secure the loan from Mr. Ponsonby of one of the original specimens collected by Miss M. Bowker at Somerset East. I have also examined one specimen, collected by the late Mr. Crawford, in Mr. Ponsonby's collection, three specimens (co-types of "E. callista") in Mr. Ponsonby^s collection, and three specimens collected by Mr. Farquhar at the same time as the type of "E. callista," two of which are in his collection and one in mine. All these specimens were found at Somerset East, the locality, " Dassy Krantz, Grahamstown," given in the description of ^'E. callista," being an error arising through the interchange of the contents of two boxes. Thus Somerset East remains the only known locality for E. mari^. The other shells affected by the interchange were those described as "E. periploca"; so Somerset East cannot be accepted as a locality for E. farquhari, of which "periploca" is a synonym, on our present knowledge of its distribution. The tooth on the columellar lip is not connected with the internal columellar plait, as stated in the original description of E. maria?, but is quite distinct as defined in the description of "E. ; A narrow axial perforat
