smooth as is usual in this species, it being corrugated and pre- 
senting numerous small roughnesses. The surface of the other 
specimens agrees very well with that of the typical Amorphina 
pamicea Pallas (O. 5.). The oscula are small, dispersed and 
slightly elevated. The spicules are of the same size and form 
as those of Swedish specimens. 
Colour. Yellowish, not so much varying as in Swedish 
and English specimens. 
Habitat. Vardö, depth 60 fathoms (3 Sp.); Möller Bay, 
depth 15—20 fath., (48 N. 5.); Waigat Strait, north from Disco- 
island, depth 20—35 fath. (S.).

Amorphina fallax Bow. (Eristedt) or not. [He spiemlestane 
of the same kind and size, viz. slightly curved, acuate, some- 
times spinulated, the length being about 0,4 mm. The dis- 
position of the spicules is likewise the same as in this species. 
The colour of the species from the expedition of the Vega 
is more yellow than that of the Swedish specimens, which are 
of a more or less light ash-colour.; ”Phe surface 15 smooth 
The largest specimen is attached to a Laminaria, forming a 
finger-like body; the length is 50 mm, the diameter inomer 
ceeding 15 mm. OÖOscula are generally minute, dispersed; one 
of them on the top of the sponge is larger. Consistencey soft. 
The other specimens from the expedition to Nova Zem bla 
in the year 1875 are much smaller and of a lighter colour, 
agreeing more than the first-mentioned with Swedish specimens.
