This very large and handsome species is common on the deep-water fishing 

 grounds off Nova Scotia and Newfoundland. From the Gloucester fishermen 

 over 120 specimens, mostly of large size, have been received by the U. S. Fish 

 Commission, all of which have been examined by me. These were received 

 in 83 lots, from 1878 to 1881. They were taken in 120 to 350 fathoms, on the 

 outer slopes of the Grand Bank, St. Peter's Bank, Western Bank, Banquereau, 

 Sable Island Bank, Le Have Bank, and George's Bank. Previously, it was 

 known Irom only a few Norwegian specimens, from Christiansund, Bergens- 

 fjord, Lofoten, Banenfjord, etc., in 150 to 200 fathoms. 



A young specimen was dredged by the U. S. Fish Commission, off Nan- 

 tucket and Martha's Vineyard, in 224 fathoms, in 1881; also three large and 

 perfect specimens, in 317 and 640 fathoms, and a very young one, in 192 fath- 

 oms, in 1882. One of the largest of these was 530 mm. (about 20.5 inches) 

 high, and 146 mm. broad; length of the largest wings, 64 mm.; their breadth, 

 38 mm.; diameter of l)ulb, 38 mm.; length of stem, below the bulb, 112 mm. 

 Color of the wings and rachis, in life, deep orange; upper surface of bulb, 

 orange-red. 



Among our specimens there is considerable variation in the relative size of 

 the wings and in their form; in some cases they are long and acute-triangular; 

 in others, they are much broader and not acute. The color varies from dull 

 orange-yellow to deep orange-red.

A young specimen of this species, in the collection, is 70 mm. long ; 3 nmi. 

 broad, across the polyi)iferous part; the barren peduncle is 35 mm. long ; 2 mm. 

 in diameter. Where most developed, there are two polyps in each oblique 

 row, supported by two-lobed spiculose calicles; between the wings there are 

 four to six scattered zooids. Toward the upper part of the peduncle there is 

 but one well-developed polyp, with or without an additional young bud, in the 

 oblique rows; and here the calicles have the apex bilobed ordy sliglitly, or not 

 at all and terminating in a single pointed group of spicula. This part agrees
