this species is with us* a midwater form. The fact of its 
being present at the surface in the bay may not mean 
anything more than that the bay water is a mixture of 
various layers, caused by the tidal currents in shallow 
water or by an off-shore wind which has carried the 
surface water out and allowed deeper layers to well up 
from below. 
The following table shows the distribution in the 
nets in detail; and although the record for the year ditters 
considerably from that of 1907, still it is not incompatible 
with the view expressed in last year’s report that this may 
be a species which periodically invades our area. The 
numbers present in the earher months of 1908 may well 
be remains of the previous autumn’s invasion. It will be 
noticed that in April they were mainly caught in the 
Hensen and Nansen nets hauled from 20 to 10 fathoms, 
out at sea.

* Sars (Crust. of Norway, Vol. IV, p. 157) says that on west coast of 
Norway ‘‘ it only occurred in depths of more than 150 fathoms; and it 
thus appears to be a true deep-water form.”’
