LIST OF LABRADOR MARINE ANIMALS. 405 



Asterias vulgaris Stra. (Asteracanthion rubens, M. and T.) 

 Common just below low water mark. The largest specimens from 

 8-10 inches across. 



Asteracanthion polaris M. and T. Occurring with and as 

 common as the preceding, if not more so. Often taken, especially 

 the young in 10-15 feet. 



A. n. sp ? Large specimens measuring 20 inches across fre- 

 quently occurred in pools at low water mark. The color in life 

 was a light greenish hue, mottled with reddish brown. 



Foxopneustes drobachiensis Ag. (E. granulatusSay.) Specimens 

 measuring four inches across were often taken at low water mark. It 

 extends to 50 feet, at which depth it was dredged on the Bank fre- 

 quently, where the specimens were uniformly small : but after a 

 careful study I cannot see any permanent specific differences. I 

 cannot see that it differs at all from individuals collected during 

 the past summer at Eastport. 



A specimen in my possession from Greenland seems to be very 

 distinct from our Labrador andMaine species. The periphery is dis- 

 tinctly pentagonal. The whole shell is more elevated; while 

 the sides of the shell are not so full and rounded as in our spe- 

 cies, the ambulacral plates are not slightly depressed, nor that area 

 so distinctly marked as in ours. The tubercles are fewer and pro- 

 portionately larger ; thus in the Greenland species there are 20 

 tubercles in a row along the narrowest interambulacral zone, in 

 ours 28. In the broader interambulacral zone there are 15 papillae 

 in the Greenland species; in ours, 18. Moreover there are fewer 

 flutings in the spines taken from either end of the shell than in 

 ■our species. 



Echinarachnius parma Gray. (E. atlanticus Gray). Abun- 

 dant and large on saudy bottoms in 2-15 feet. 



P solus Fa bricii Liitken. Two were taken in 15 feet on pebbles 

 in Esquimaux Bay. 



Pentacta calcic/era Stm. (Cucumaria Koreni Liitken). One 

 was taken in 15 feet sand, in Salmon Bay. 



Pentacta frondosa Jaeger. One specimen was thrown upon 

 the beach. 



Chirodota laeve Grube. Very fine specimens, eight inches 

 long, were abundant in 10 feet sand in Salmon Bay. 



Eupyrgus scaber Liitken. Several were taken in 10 feet sand 

 in Salmon Bay. It has not occurred so low down the coast 

 before.
