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 MIS Hes UTI andis ive times tl the pees of this.
