DISTRIBUTION. 



Of the eight species here mentioned five have been collected 

 only on the Pacific coast of North America. Of these five, 

 three are new and each was found in but one locality, viz., 

 Epiactis ritteri at Popof Island, Charisea saxicola at Sitka, 

 and Harenactis attenuata at San Pedro. 



E^iactis -prolifera is common in Puget Sound and at several 

 points on the California coast as far south as Pacific Grove, 

 about one hundred miles south of San Francisco. 



Crtbrma {Evactis) artemisia is, so far as I know, not found 

 south of Puget Sound, where it was originally discovered by 

 Pickering, of the U. S. Exploring Expedition. The Harriman 

 collections extend its known range along the Alaskan coast to 

 Dutch Harbor. 



Of the three species, not peculiar to the western coast of 

 North America Edivardsia stpunculoides is the least widely 

 distributed. It was originally described by Stimpson from 

 a single living specimen taken at Grand Manan Island, 

 New Brunswick, and has since been found in great abund- 

 ance in the neighboring locality of Eastport, Maine, by 

 Verrill. 



These are the only places in which it is known to occur, with 

 the possible exception of Henley Harbor, Labrador, where an 

 imperfect specimen of an Edivardsia having twenty-four tenta- 

 cles was dredged. This was noted by Packard in 1865. E. 

 stpunculoides is clearly a northern species, and will probably 

 be found at other points along the coast between Labrador and 

 Alaska. 



Urticina crassicornis is a circumboreal species, having a 

 north temperate and arctic range. It is found on the Atlantic 

 and northern shores of Europe, in Spitzbergen, Iceland, Green- 

 land, on the Atlantic coast of North America south to Cape Cod, 

 and on the northern and western coasts of North America south 

 to Puget Sound. 



Metridium dianthus has about the same distribution, reaching 

 farther southward, however, in both Europe (Mediterranean) 

 and America (Cape Hatteras and San Francisco).
