Barentsia major Hincks. 



Osburn, 1912, p. 213. 



Occasional throughout the waters of the region, 

 growing on shells and stones. Dredged by 

 the Survey almost wholly in Buzzards Bay, 

 in 3 to 13 fathoms, on various sorts of bottom- 

 Off Gay Head, on leg of spider crab; piles at 

 Nantucket, on Chondrus crispus. 



Fish Hawk stations: 7611, 7645, 7709. Supple- 

 mentary station (1909): 7659. 



Phalarope stations: 135, 165, 167. Supplemen- 

 tary station (1909): 146 (i). 



Barentsia discreta (Busk). 

 Osburn, 1912, p. 214. 



A colony of several dozen individuals that seem 

 to belong to this species was taken by the sur-

vey in the eastern part of Vineyard Sound, at 

 Fish Hawk station 7777, in 5^2 fathoms, grow- 

 ing on a shell fragment, and again off the 

 eastern end of Naushon Island, in n fathoms, 

 growing on a pebble. Taken in 1909 at two 

 repeated stations (7660 and 7668) in the lower 

 end of Buzzards Bay, 6 to 10 fathoms. 

 The species has heretofore been known only 

 from the type locality, Tristan da Cunha, in 

 the middle of the South Atlantic Ocean, 

 where it was dredged in 100 to 150 fathoms, 

 off Nightingale Island. Busk (Challenger 

 Report. There listed as Ascopodaria discreta

Vineyard Sound, common. Verrill. Abundant 

 and universally distributed in Vineyard 

 Sound; common in many parts of Buzzards 

 Bay. Dredged by the Survey in i to 17 

 fathoms on all sorts of bottom. Recorded 

 also from shores and piles of wharves in 

 nearly every part of the region.
