3g4 P Kramp. 



Hab.: St. 99. 

 Depth: 300m. 



Geographical distribution: Arctic: Greenland, Northern 

 Norway, Murman Sea. — British Isles, Bay of Biscay, Morocco. 

 Not earlier known from East Greenland. 



Genus Ciispidella Hincks. 



Cuspidella procumbens n. sp. 

 Plate XXIV, figs. 2—6. 



Tro ph о some: The hydrothecae, which are several times longer 

 than broad, everywhere of the same breadth, on an average 136 /u, 

 spring from a filiform, smooth or irregularly wrinkled, creeping, 

 branched stolon ca. 55 /j. thick. The height of the operculum is 

 almost as great as the diameter of the hydrotheca; there are 10 — 14 

 (on an average 11.9) facets in the operculum. The proximal part, 

 usually the half, of the hydrotheca sticks to the support; the distal 

 part bends upwards so that the upper part is quite or almost quite 

 vertical (PI. XXIV, fig. 2), just as in Lafoëa serpens. The proportion 

 betw^een the free and the attached part is very variable, especially 

 when the support of the colony is irregular. Regarding the structure and 

 development of the operculum see p. 379 — 380 and PI. XXIV, figs. 3 — 6. 

 — Owing to the bad state of preservation I can say nothing with 

 regard to the structure of the hydranths. 



Gonosomes: It has not been possible for me to discriminate 

 these. 



Very abundant at several stations, chiefly on hydroids and 

 Bryozoans, yet not rarely on Delesseria, — Regarding the relation of 

 this species to Lafoëa serpens, see p. 374.

Depth: 6— 60 m. and at 300 m.
