VEGA-EXPEDITIONENS VETENSKAPLIGA ARBETEN. 393 
No specimens of Lafoéa grandis, Hincks (L. fruticosa, 
EERO Är sv andas). Clatke) or I capitlaris, G-0OXSArs; 
occur in the Vega collection. They are probably exclusively 
deeper water forms. 
Lafoöa sibirica, n. sp. 
BI nord 
Stem creeping, very delicate; hydrothece minute, with the sides 
straight or very slightly curved inwards in the middle; aperture entire: 
hydrothece about 0,28 mm. in length borne on stoutish ringed pedicels 
with about 6 to 8 rings. 
This little species is very like our British £L. pocillum, but 
differs from it in the larger size of the hydrothecze, and per- 
haps to a slight extent in their straighter sides. S. F. Clarke 
describes an Alaskan form as L. pocillum, which is very likely 
the same as this. 
Bocla Lat 0 NS Lone. 1738-24 WI12—-15-fathoms: 
Salacia abietina (Sars), Hincks. 
Campanularia abietina, Sars (Reise i Lofoten, 1850). 
Grammaria abietina, Sars (Bemeerkn. over fire Norske Hydr., 
1862). 
Good and typical specimens occur from the station in 
Long. 113? 30 E., at a depth of 15 fathoms. The species does 
öccEITr mm. Clarke s Alaskan lust, and this therefore. is Its most 
easterly record; but it occurs on both sides of the N. Atlantic 
region (Stimpson, Grand Manan). 
Sertularella gigantea, Mereschkowsky. 
This species does not occur in the collection from farther 
East than 113? 30' E. long. The specimens from that locality 
are identical with those I have before exarnained in the Willem 
Barents collection from Barents Sea: and are probably identical 
also with the large variety of S. polygonmias figured by Clarke 
from Alaska, although the Vega brings no specimens from 
intermediate stations. Kirchenpaur mentions specimens from 
Kamtschatka in the Leipzig collection. Hincks” Greenland 
specimens are no doubt also identical!, and the form is no 
! D'Arecy W. Thompson, Hydroids of Willem Barents Expedition,
