 A single specimen was caught on the 

 Carlsbergfond Expedition by Mag. sc. 

 Søren Jensen at Canning Land (71°30' 

 N, 2Г55' W), 202 fathoms, Vo 1900. 



It is a young colony, broken just below 

 the polyp-bearing part of the rhachis; the 

 soft parts below the fracture are, how- 

 ever, still adherent but badly damaged and 

 without any calcareous axis. The total 

 length is — approximately — 123 mm., 

 the breadth across a pair of opposite wings 

 in the middle of the rhachis с 2 mm.; the 

 diameter of the rhachis between the wings 

 ca. 0,8 mm. ; ca. 17 sets of wings are pre- 

 served, the upper ones, as usual in the 

 genus Virgularia, rudimentary towards the 

 naked end of the calcareous axis; the 

 number of polyps in each wing mostly 4; 

 the polyps of each wing coalesced to the 

 calyx openings, which are toothless; the 

 lines of attachment of each wing very obli- 

 que; the opposite wings are in contact along 

 the mid-ventral line of the rhachis; zooids 

 few, scattered in the diastemes between 

 the wings, not visible from the dorsal face 

 of the rhachis; the radial canals on this 

 side form a longitudinal swelling along the 

 rhachis. 



In spite of the damaged condition the 

 single series of "stalk-zooids", characteristic 

 of the genus Virgularia, is plainly visible 

 with a strong lens. 



The facts mentioned, as well as the 

 figures, clearly show this specimen to belong 

 to the genus Virgularia; only as to the 

 species some doubt might be entertained. 

 At first I thought to have before me a new 

 species, but very nearly related to V. affinis.
