SHALLOW-WATER STARFISHES 337 



SPECIES WRONGLY ATTRIBUTED TO THIS FAUNA. 



Asterias rubens Linn. Ives (1890) recorded this from San Luis 

 Obispo. Murdoch recorded it from Point Barrow, Arctic Ocean. 

 The latter proves to be Allasterias rathbuni Verrill. 



Asterias lurida Phil. Ives ( 1889) recorded this from San Diego, 

 California. It is a Chilean species and not likely to be found in 

 Californian waters. The species mistaken for it is uncertain. 



Linckia guildingii Gray. This species is known only from the 

 West Indies and Bermuda. It was recorded with doubt by Ives 

 ( 1889) from San Diego. Probably his small specimen was the young 

 of L. Columbia. 



For southern (Panamic) species recorded from San Diego or fur- 

 ther north, see below, p. 346. Perhaps some are errors as to locality 

 due to misplaced labels. 



GEOGRAPHICAL DISTRIBUTION. 



The following account of the geograhpical distribution of the 

 shallow-water species included in this paper is intended merely to 

 give the general facts, so far as now known to me. No doubt the 

 elaboration of the extensive collections of Forcipulata made by the 

 steamer Albatross, from deeper waters, will very materially change 

 the range of many species now known only from the shores and 

 very shallow waters. 



For my present purpose, the entire region may be divided into 

 four great faunal districts: 



I. The Beringian or North Alaskan. This includes the Arctic 

 Ocean coast of Alaska and all the coasts and islands of Bering Sea, 

 south to the Aleutian Islands and Alaskan Peninsula. 



II. The Columbia- Alaskan. This includes the coasts and islands 

 of Alaska, south of the Aleutian Islands, and the entire coast of 

 British Columbia, with Vancouver Island; Puget Sound, and the 

 northwestern coast of Washington; the Gulf of Georgia; and the 

 Straits of Fuca. 



III. The Californian. This includes the middle and southern 

 parts of the coast of Washington ; all of the Oregon coast ; and the 

 coast of California to Point Conception, or the north end of the 

 Santa Barbara Channel. 



IV. The South Californian. This includes the coast of southern 

 California, from the Santa Barbara Channel, Santa Rosa Island, 

 and Santa Cruz Island to the middle part of the Lower Californian 

 coast.
