Ophioglypha rubusta (Ayres). 



Ophiopholis robusta, Ayres (1852). 

 Ophioghjpha robusta, Lyman (1865). 



Grand Manan, " abundant in the laminarian zone, and sometimes also at 

 low-water mark on rocky and nullipore bottoms. A small graceful species^ 

 with flat disk and long slender arms tapering to mere threads. It is always 

 highly coloured, usually variegated with red, but sometimes jet black '' 

 (Stimpson). 



In the Gulf of St. Lawrence specimens of 0. robusta were dredged by 

 the writer between Anticosti and the Gaspe peninsula, in 110 to 220 

 fathoms, in 1872 ; also on the Orphan Bank and at the entrance to Gaspe 

 Bay, in 20 to 50 fathoms, in 1873. Miss Bush says that it was " the most 

 abundant species " obtained by the Stearns expedition, and that it was 

 taken at L'Anse au Loup, Henley Harbour and Temple Bay in 10 to 15 

 fathoms. Dr. Bell collected it at Port Burwell, Hudson Strait. The 

 species is known to range from Massachusetts Bay to Greenland, the 

 Arctic Ocean, northern Europe and Alaska, and in depth, from low-water 

 mark to 220 fathoms or more.
