and the only larger numbers are on exceptional occasions, 
when the “pulley” net, for example, obtained 200 at 
Station 1 on August 19th, and the coarse net in September 
obtained hauls of 200, 500, 600, up to a maximum of 700 
and 790 on several occasions. 
MICROCALANUS IN 1908. 
The small Copepod J/tcrocalanus pusillus appears for 
the first time this year, in the bay surface nets, on 
February 4th; and on February 6th and April 2nd it 
occurs’ again. Throughout April it is_ practically 
restricted to the Hensen and Nansen nets open only 
between 20 and 10 fathoms, with the exception of hauls 
on April 24th and at Station IIT on April 29th, when the 
nets were open to the surface. After April 29th for nearly 
two months no specimens were found. It must be 
remembered that dufing May and June the yacht was not 
at sea, and the only collections taken were those across 
the bay. It is posseble therefore that Jlicrocalanus may 
have been present outside the bay during this period 
when it was apparently absent in the bay. On June 25th 
and August 5th the species occurs again in the bay nets. 
From August oth to September 14th it occurs only in the 
Hensen, Nansen and weight nets (some of which, on 
August 17th and on September 12th, were hauled from 
greater depths—down to 60 fathoms), with the exception 
‘of a large catch of 300 specimens in the coarser surface 
net at Station I, on September llth. The frequent 
occurrence of this form in the Hensen and Nansen nets 
hauled from 20 to 10 fathoms, and in the weight net in 
the latter part of the year, the almost entire absence 
from the surface nets, and the comparatively small 
number taken in the Hensen net on August 17th—which 
was hauled from 60 to 50 fathoms—seem to indicate that
