GAMMARIM. 
Stimpson, is a character of the male sex. The rest of 
the animal bears a near resemblance to B. pilosa. 
It was sent to us by our kind correspondent in com- 
pliment to whom we have proposed the specific name 
employed above. It was taken by Mr. Robertson in the 
month of February, in sand pools near low water njark 
at Cumbrae, N. B. He informs us that they were nu- 
merous, darting hither and thither. 
Two specimens have since been dredged by our friend 
Mr. J. Gwyn Jeffreys in the Shetlands. 
The observation of Mr. Robertson appears to over- 
throw our suggestion as to the burrowing habits of these 
animals mentioned in the description of the previous 
species. It is curious to remark that in this species 
the animal is furnished with distinct eyes in the spe- 
cimen from Cumbrae, but not in those from the Shetlands 
which had been longer in spirits ; it is, therefore, ques- 
tionable whether the organs of vision had disappeared 
from the others after death (as they frequently do in 
some species) inasmuch as we received both specimens 
after they were dead.
