There is an ere£l tooth in the upper valve of this Ihell, 

 near the beak, fomcwhat fimilnr in {h.ipe to the 

 ereat one in the M. lal'^nria. This fits within a redl- 

 angular tooth in the lower valve, which likcv/ife 

 contains four remote teeth, like laminae, rcccivii)g 

 between them two from the upper valve. 



I have referred for this (hell to Mr. Pennant's Telllna 

 radiata, as both his defcription and fig,ure agree ex- 

 adtly with the Linnean M. /lultorum. His fhell of 

 that name (iVb. 42. /. 52. y. 42.) is, perhaps, only a 

 young one of the M. folida.

I believe we are indebted for the difcovery of this fhell 

 to that accurate conchologift, William Boys, Efq. 

 who found it an the Sandwich fhore, where I have 

 fince met with it in abundance. 



The hinge has the true fpoonlhaped cavity pecuhar 

 to the genus Maara, with a fmall tooth fituated 

 clofe to it in the upper valve, which has no remote 

 teeth. The lower valve is provided with two.
