the minnows,” it is found one to a hundred of the 
Gammari. 
Johnston found it at Berwick, and presented the speci- 
men to the British Museum under the name of G. 
punctatus, The G. punctatus of Say, which we take to 
be identical with Stimpson’s A. virescens, has, in both 
Say’s and Stimpson’s description, parts sufficiently dis- 
tinct to separate it from the British species. 
A. littorina is to be found most probably all round our 
coast. Our friend, the late Mr. Geo. Barlee, sent it to us 
from Skye, and the Rev. Geo. Gordon from the Moray 
Frith. We have seen a specimen taken by the Rev. 
A. M. Norman in the Outer Skerries Harbour, Shetlands. 
Dr. Johnston found it very common amongst confervae in 
pools left by the tide near Berwick. Mr. Webster has 
forwarded to us specimens from Tenby; and we have 
found them common between the tide marks at Plymouth. 
Professor Kinahan has taken it in county Clare, Ireland. 
Mr. Jeffreys has also found it on the coast of Normandy, 
but we do not remember its having been among the 
Crustacea found by him on the coast of Italy. Mr. Rayner 
has found at Hummock’s Island, Basse’s Straits, a speci- 
men that appears to be identical with this species ; and 
we can detect no character of sufficient importance that 
will identify A. Picta of Rathke, from the Crimea, as a 
distinct species. 
We believe that this species frequently constructs its 
nest by rolling together the edges of a leaf of growing 
seaweed and cementing them together so as to form a 
tube open at each end. We observed the fact some time 
since but have not since verified it. Dr. Johnston de- 
scribes the “ burrows ” of his G. punctatus as being from 
one to two inches long, composed of pieces of seaweed,
