This is not the 7". Conulus of Linn/Eus. It lias much 

 the habit of T. ziziphinus, but on comparifon will be found 

 perfe6lly diftintl ; that fhell not pofleflQng the fine crenu- 

 Jated ridges, fo confpicuous in this fpecies ; is alfo more 

 pyramidal than that fhell; and mofl times readily diflin- 

 guiflied by the crimfon tip. 



Da Costa received it from the coaft of DevonJJiire ; 

 and fays that it is not uncommon on the SuJJcx coaft. 



Doclor Maton In lils Wejlern Tour fays, he found it at 

 Treryn cove, near the lands end, in Cornwall. 



Doftor PuLTENEY glvcs it as a Dorfct fiiell, but fpeaks 

 of it as rare. We have not been fortunate enough to find 

 it either on the Devon or CorniJIi coafts, and confider It as 

 a fcarce fliell in England, never having occurred to us, ex- 

 cept on the fhorc between Weymouth and Portland.
