42 VERRILL ON THE POLYPS OF THE 



within the province of the present paper. It has heen called the Floridian Province by 

 Dana, and the West Indian Fauna by others. The following brief conspectus will show the 

 relations of these faunae more clearly. 



Syrtensian Fauna. This embraces the southern coast of Labrador, the Straits of Belle- 

 Isle, the Banks of Newfoundland, banks off the mouth of the Bay of Fundy, and St. George's 

 Bank. The three polyps known from this fauna appear to be circumpolar, but are not 

 found in the next. 



Acadian Fauna. This extends along the coast from the mouth of the St. Lawrence to 

 Cape Cod, embracing partially the island of Anticosti, the Magdalen Islands, Breton Island, 

 and perhaps the southern coast of Newfoundland, and extending to Nantucket Shoals, and, 

 as has been suggested by Dr. Stimpson, to a bank off the coast of New Jersey, from which 

 Zoanthus parasiticus has been obtained, associated with many northern species. Of the ten 

 species found in this fauna, but one (Metridium marginatum) is known to extend into the 

 Virginian ; and one other [Rhodactinia Davisii) probably occurs in the Syrtensian. 



Virginian Fauna. This embraces the whole extent of the coast from Cape Cod to Cape 

 Hatteras. Five species are considered as peculiar to this fauna. 



Carolinian Fauna. This extends from Cape Hatteras to St. Mary's Biver, Florida. There 

 are eighteen species found in this region, none of which are known to extend to either of 

 the others, or to the West Indian. 



Syrtensian Fauna.

 mination, but resembling this species, were collected on the coast of Labrador by Mr. A. S. 

 Packard, Jr.
