spination is also very minute, and in order to be observed 
accurately requires a microscopical power of about 500. Thus 
I have been able to see a very minute spination of this spicules 
also in Swedish specimens. It is therefore without doubt that 
our arctic specimens and those from the coast of Sweden, as 
well as the specimens described by Carter and Vosme&er, are 
identical. The peculiar difference between Swedish specimens 
and those described by Carter, on one side, and specimens from 
the arctic regions and Suberites spec. Vosmer, on the other, 
exists only in the external shape. Specimens of the two 
latter kinds are deprived of the light layer of sarcode on the

as different species or varieties. Carter has probably over- 
looked the microspination of the above-mentioned spicules. 
The largest specimen is 50 mm in diameter, rounded and a 
little depressed. Several specimens have the size only of a 
 hazel-nut. 
The surface is smooth and even, sometimes gelatinous. 
Most specimens grow freely, only a few are attached to worm- 
tubes, stones and other hard objects. 
The colour is greyish or grey with a tint of yellow.
