small tubular galleries, excavated in the mud, over which 
the tide flows and ebbs. It has not, however, been 
ascertained whether the channels in the mud are per- 
forated by these Crustacea or by the numerous annelids 
that it preys upon. Q-uaterfages, in his pleasant 
“ Hambies of a Naturalist,” says, “ that at about the 
end of April they come from the open sea in myriads 
(they are called Pernis by the fishermen of the coast of 
Saintonge) to wage war with the annelids, which they 
entirely destroy before the end of May ; they then 
attack the mollusca and fish all through the summer, 
and disappear in a single night about the end of October, 
and return again the following year.” It is one of these 
fierce combats with an annelid that we have represented 
in our vignette. 
This species may probably be found all round the 
British coast, and it would be interesting if local na- 
turalists should be able to confirm the information 
derived from the fishermen on the coast of Saintonge. 
We have taken several specimens in calm weather during 
the month of July, amongst weed attached to a buoy 
in Plymouth Sound, associated with Podocerus ; but we 
have not, among the many that have been sent to us, 
received any remarks from our correspondents relative 
either to season or situation in which they had been 
found, and therefore assume their habitats to be as 
commonly reported. 
They have been recorded or sent to us from Berwick 
by Dr. Johnson ; from the Moray Frith, by the Rev. 
G. Gordon ; from Norfolk and the mouth of the Med- 
way, by Dr. Leach ; and we have taken them in Loughor 
Marsh, Glamorgan. Quatrefages speaks of their abund- 
ance on the coast of Saintonge. Mr. D’Orbigny has 
recorded them from the Bay of L’Aiguillon, near
