Fig. 28 D 



A small (i/4 inch) shell common in salt marsh 

 pools and brackish waters froo James Bay and 

 Labrador to New Jersey; often found on sea weed 

 in New Jersey Inland Waterways. It can often be 

 obtained by drying* masses of Sea Lettuce (Utva) 

 and then shaking- it thoroughly and collecting the 

 small shells that were adhering to it. 



Littorina litorea Linne (Periwinkle; Wrinkle) 



PLATE XX. Fig. 6 



This thick black shell is the most conspicuous 

 member of the littoral marine fauna from Labrador 

 to Long Island. It is said to have been accidently 

 introduced into Nova Scotia from the Old World 

 about 1863 and has since migrated north and south 

 along the coast. It is usually associated with a 

 rocky coast and is therefore not to be expected along 

 the sandy shores of Xew Jersey. However, the 

 rock breakwaters along the coast have in recent 

 years afforded a habitat for this species and it is 

 now firmly established at a number of places along 

 the New Jersey coast. As far as is known, Cape 

 May is the southermost point that the Periwinkle 

 has yet been reported. 



In Great Britain and other European countries 

 these periwinkles are used as food and are regarded 

 as quite a delicacy. In Newfoundland, where they 

 are known as "Wrinkles" they are also frequently 

 eaten.
