54 lucinidje. 



British example we have seen was dredged by Mr. Jeffreys, 

 iu twenty fathoms, at St. Mawe's Creek, five miles from 

 Falmouth ; the same locality from whence the original 

 specimen was procured. Both shells greatly surpass the 

 ordinary dimensions of the Mediterranean ones. 



Poli's figure (Test. Sicil. vol. 1, pi. 15, f. 25) and de- 

 scription of this shell are by no means characteristic, and 

 appear to have been modified from a fancied identity of 

 his species with the larger West Indian Lucina, usually 

 known by the name we have applied to the present shell. 

 The valves of Strigilla divaricata, stated by Turton (Di- 

 thyra Brit. p. 120) to have been picked up on Teignmouth 

 Beach, belong to the Transatlantic mollusk,

 their striae " not very close," '* the margin plain," &c.
