Esq. ; and the fragments of shells which are agglutinated indiscrimi- 

 nately to the area of the whorls are very much hroken in all, though 

 the shells to which they are agglutinated are in every respect live 

 and perfect.

The method or disposition of the agglutinated fragments in this 

 species is very peculiar and distinct from that in any other. The 

 generic property is here confined to the base of the whorls, and the 

 fragments which become attached are all inserted edgewise, ranging 

 with great regularity side by side. The specimen above described 

 is in the collection of the Rev. Mr. Stainforth. 



Mr. Cuming exhibited to the Meeting the various species of Pho- 

 rus referred to in the above communication, and also a series of spe- 

 cimens of the genus Pecten, descriptions of which, by G. B. Sow- 

 erby, Jan., were read. The species described are figured in Sow- 

 erby's ' Thesaurus Conchyliorum.'

 the general characters of the species indicating some degree of aftinity 

 with the group containing P. Rudula.
