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 
Comiission, 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 from 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 bulb, 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 mm. 
broad, across the polypiferous 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 zodids. 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 only slightly, or not 
at all and terminating in a single pointed group of spicula, This part agrees
