A single specimen of this interesting species was obtained in the material 
from station 3. It is typical of the cold water form of this species. Records 
of its distribution range as far north as 83°19’N., at a depth of 72 fathoms. It 
is also known from off Nova Zembla and the coasts of Europe. I have recorded 
it on the Atlantic coast from the Woods Hole region. This is probably different 
from the species so common in shallow water of the South Pacific which has 
_ been assigned to this of Williamson.

A small specimen very similar to Brady's original figure with the beading 
of the ventral side extending about half way from. the periphery to the umbilicus 
occurred at station 3. From station 5 there is a better developed specimen 
which has become somewhat flatter on the ventral side, and has the beading
