466 Messrs. J. C. Melvill and J. H. Ponsonby on 



rather narrow velvety black band ; this is preceded on each 

 side by a transverse white line which, close to the suture, 

 gives off an oblique white line in the direction of the basal 

 tubercle ; and in the angle thus formed, which has an inner 

 fulvous-brown border, there is a third very short white 

 line. The part of the elytra between the innermost oblique 

 lines is velvety black. With the exception of a narrow 

 bluish-grey transverse spot the whole of the elytra succeeding 

 the median black band is covered by a delicate fulvous-brown 

 pubescence. The elytra are furnished in addition with some 

 widely scattered long fulvous bristles. A few punctures are 

 to be seen on the basal third. A pubescent white line passes 

 along the dorsal margin of each of the legs. The femora are 

 subfusiform, pedunculate at the base. 



This species at first sight resembles very much A. bicuspisj 

 Chevr., but is easily distinguished by the difference in the 

 punctuation of the elytra and other characters. 



LV. — Descriptions of four new Species of Terrestrial Mollusca 

 from South Africa, xoith Observations on Helix Iluttoniai 

 (Bens.). By James CoSxMO Melvill, M.A., F.L.S., and 

 John Henry Ponsonby, F.Z.S. 



Amongst numerous specimens of terrestrial and fluviatile 

 shells recently collected at or near Port Elizabeth by Mr. J. 

 Crawford are many undoubtedly new to science. Some of 

 these were in the first instance placed in the hands of M. 

 Morelet, who last year contributed a paper on this subject to 

 the * Journal de Conchyliologie.' Since then Mr. Crawford, 

 who has received much valuable assistance from Messrs. 

 Farquhar, Leslie, and Langley, from various neighbouring 

 localities, has remitted fresh material, of which the following 

 four species may be regarded as the primary outcome ; and 

 we are hoping before long to offer a second commuuicatioQ 

 with further descriptions of other forms new to science. 



We must not forget to thank Mr. Edgar A. Smith, F.Z.S., 

 of the Zoological Department, British Museum, for kind 

 assistance.
