of this species has built several nests. These nests 
were somewhat pear-shaped, the largest end being 
upwards, and the entrance situated laterally near the 
top. 
The favourite habitat of most of the species of this 
genus is among the weeds and zoophytes that grow thickly 
at the water-line of buoys. Here we have often taken 
them in fine summer weather. But our experience in- 
duces us to believe that, when the wind raises high the 
waves of the sea, they seek shelter in the quiet depths 
of the ocean. 
We, as well as Mr. Howard Stewart, have taken this 
species frequently at Plymouth ; we have also dredged it 
in Oxwich Bay, Glamorganshire. Mr. Norman has sent 
it to us from Cullercoats, and Mr. Edward from Banff. Mr. 
Robertson has procured some fine specimens at Cumbrae, 
and the late Mr. Barlee took it near Penzance. 
The near resemblance of this species to Podocerus 
validus of Dana, demonstrates, as we have previously 
noticed, the close resemblance between the European 
and South American Crustacea.
