 Henricia sanguinolenta (O. F. Muller). 



Plates 50 and 51. 



Type : This species was described from Torekov, Sweden, by Retzius. 



Distribution : Henricia sanguinolenta is circumpolar and circum- 

 boreal and has been taken from the tide-line down to depths of 1000 

 meters; one record gives a depth of about 2450 meters. It is found 

 on the east North American coast from the Arctic down to Cape 

 Hatteras, N. C. ; also on the coasts of Greenland and Iceland ; across 

 the American Arctic and on the American Pacific coast down as far 

 as Washington State; and on the Asiatic coast down to the Kurile 

 Islands. In European waters it is found in Scandinavian Seas from 

 the Baltic to the Arctic region; rather common on all coasts of the 

 British Isles excepting the Channel coasts. It is also found southward 

 to the Bay of Biscay and the Azores.

Color: The color of this starfish varies from entirely blood-red 

 specimens to entirely yellow ones.

 the brood-protecting species. The parent attaches itself by means of 

 the tube-feet in the distal part of the rays to the underside of a stone,
