C. with eight valves, apparently fmooth, but when 

 examined with a glafs, will be found to be rough like 

 fhagreen, except on the elevated dorfal ridge ; margin 

 furrounded with tufts of whitifli hair, one at the jun6tion 

 of each valve, and two in the front, making eighteen in 

 number ; colour brown, or dark cinereous : length five- 

 eighths of an inch, breadth rather more than two-eighths. 



Doftor PuLTENEY obfcrvcs, this fliell is not uncom- 

 mon on oyRers from Poole. We have found it in confide- 

 rable abundance in Salcomb bay in Devonjhire, with all 

 the other fpecies except the albus and crinitii.s, and is by 

 far the mofl common ; like the reft it adheres to ovfters 

 and other (lielLs, as well as to ftones ; and with them in- 

 habits the deep, fo that it is only to be obtained by 

 dredging. It is alfo found at Sandwich in Kent, where 

 it feems to be not uncommon ; as among a parcel of thefe 

 fliells we received from Mr. Boys, the greater part were 

 of this fpecies. On the coaft of Barbary it is of a much 

 fuperior fize, not unfrequently above an inch long.
