CAPRELLIDAE OF WESTERN NORTH ATLANTIC 



103 



the faunal provinces of Johnson (1934) as modified by Hedgpeth (1953) 

 with the exception that a truly boreal fauna is not evident. Ceranie- 

 Vivas and Gray (1966) reviewed these zoogeographic provinces and 

 divided the continental shelf fauna of North Carolina into tlirec 

 assemblages, extending the Caribbean province to just north of Cape 

 Hatteras for the outer shelf. These provinces and examples of their 

 caprellid composition are summarized as follows: 



1. Arctic province (north of Newfoundland) — Aeginella spinosa 

 and Proaeginina norvegica. 



2. Boreal province (Newfoundland to Cape Cod). This province 

 has no endemic caprellids with the possible exception of Mayerella 

 limicola and receives contributions from the Arctic and Transatlantic 

 provinces.
