 From the neighbourhood of Scarborough, Yorkshire. 

 Favoured me by Mr. J. S. Miller of Bristol (as well known 

 for his elaborate work on the Crinoidea as for his successful 

 attention to other intricate departments of natural history) 

 under the specific name of holosericea ; but Gmelin's and 

 Ferussac's shell of that name is very different, being nearly 

 allied to the HelLv obvoluta, and is five times the size of this.
