others {Solaster papposus, Henricia eschrichti, and Leptasterias 

 groenlandica) occurs in Lake Melville in generally warmer and 

 much less saline water (not higher than 29°/oo). These two situa- 

 tions are bridged, in part, by Hamilton Inlet which shows inter- 

 mediate characteristics. 



The Asteroidea of Labrador are therefore primarily a cold water 

 (mixed Arctic- Atlantic) fauna characteristic of the North Atlantic 

 region, closely resembling, although considerably less rich than, that 

 of the warmer waters of western Greenland. All but one of the 

 species occur in Canadian waters to the north of Labrador (Grainger, 

 1955). The exception is Leptasterias littoralis, the northern limit of 

 which appears to be the Labrador coast. Asterias vulgaris may be 

 shown to reach southernmost Labrador in the Strait of Belle Isle, but 

 it is doubtful that it reaches farther northward. All but one of the 

 species also occur to the south of Labrador in the cold inshore waters
