﻿No. 2S. TURBO. 



Wreath Shell. 



Inhabitant a Slug 



Shell univalve, spiral and solid, aperture contracted, orbicular and entire. 

 The species which shows the character of this genus best, is the rare Turbo 

 Scalaris. 



Some of the species in this and the preceding genera, are very likely to be 

 confounded; but, by attentively observing the round or angular form of their 

 apertures, their proper families may readily be determined. Most of the 

 kinds inhabit the sea; some, fresh waters; and others are met with on land. 

 The most valuable marine specimens are fished up from deep waters, or found 

 adhering to rocks and stones, below high water mark. This is a very ex- 

 tensive genus, and a very considerable number are found on the shores of 

 Great Britain. The common periwinkle is there more extensively used as 

 food, than any of the other testaceous univalves. This shell is easily 

 gathered, as it is found on most rocks which are left uncovered by the ebbing 

 of the tide. Children are principally employed in this fishery, and the shells 

 are sold by measure. They are, in general, used after being boiled, and are 

 consumed in great quantities by the poor inhabitants of the coast. 



The generic name, Turbo, is derived from the Latin, and has the same 

 signification with the Greek derivative of the preceding genus. This species 

 is exceedingly numerous, being in ten divisions, with families.
