which we find in the colledlion of that conchologifi; affixed"; 

 to one of the fpecimens figured in the annexed plate. 



From this it appears the fliell had been picked up by Mr, 

 Platt, on the Sally rocks, at the weftern extremity of 

 Conizuall, and communicated by him to Da Costa." 



The figure is about the fize of Helix nemoralis, or rather lefs.

Mr. Donovan defcribes his fhell to be " fomewhat taper, 

 pale : whirls very (lightly bicarinated." And adds that, 

 "it is found on the weftern coafl : a fhell of very plain 

 appearance, brownifh colour, and rather flattened on the 

 wreaths, fo as to form two flight fpiral ridges or obtufe an- 

 gles, efpecially on the firfl: or largefl volution/' 



The figure of this fhell has nothing in it that can caufe it 

 to be confounded with the pallidus of Tejlacea Britannica, 

 but we fufpe6l it may be a variety of T. cra^ior, by the fize, 

 fliape, and colour ; and as the appearance of a few faint ele- 

 vated (Iria is not unufual in that fliell, a fpecimen with two 

 only might occur. 



It will be obferved in the Defcriptive Catalogue of Briti/h 

 Jhells^ publifhed in Vol. viii. of the Linnaau Tranfadtions, 

 thefe two fliells are brought together,
