Colville Channel. 35 fathoms. Sand, mud. 21/XII. 1914. 
One damaged specimen, enerusting as a 1—3 mm thick layer 
on a Shell; R. laxa seems otherwise typically to be barrelshaped. 
Skeleton fibres hardly to be seen, the skeleton consisting of a 
rather irregular reticulation; in the typical form the fibres are 
easily to be seen; I think, that the'lack of clearly marked fibres 
is due to the enerusting habit of our specimen. The shape of the 
oxea is identical with that of the specimen from the Campbell Isl. 
(Brøndsted (1)); size 190—200 x 7—8 //-, a little more siender 
than the type. 
Hitherto known from North of Iceland and the Davis Strait 
(Lundbeck) and Campbell Isl. (Brøndsted).

There is one fragment of this beautiful and interesting sponge

the fragment seems to be a piece of just such a shallow cup as 
figured by Dendy. The fragment in hånd is 50—80 x 6 mm. 
Hitherto known from near Three Kings Isl.
