MARINE BIOLOGICAL STATION AT PORT ERIN. 81. 
Anomalocera, on the other hand, first appears in our 
records on March 29th, and then only in the form of 
metanaupli (100, 170, and 30 in surface hauls off the 
Calf Island). It continues to be represented, in small 
numbers, by both adults and young, throughout August 
and September, and finally on November 8th. 
The distribution of MWécrocalanus pusillus, G. O. Sars, 
throughout the year is interesting. It appears for the 
first time im our records late in August, and remains fairly 
constantly present, but never very abundant, throughout 
the autumn until January, when it disappears. During 
the first few weeks it is only im the off-shore hauls, 
appearing first out in mid-channel on August 24th in the 
Hensen and Nansen nets thai were let down to 60 fathoms 
and hauled up vertically. As specimens were present in 
all the nets that were closed when they had been pulled 
up to 45 fathoms, and were not present in the surface and 
other nets used above this level, it is evident that this 
Copepod was on its first appearance only in the deep water 
in mid-channel. It was encountered next on August 
26th, in the weighted net hauled at 10 fathoms, on the 
inner edge of the Train Bank, some eight miles off land. 
On August 31st it made its appearance at Station I, in the 
Hensen and Nansen nets hauled up from 24 fathoms, and 
in the weighted net from 10 fathoms—the latter having 
53o) specimens. It was also present on September 2nd 
and ord, under the same circumstances. On September 
4th we again found it in mid-channel in the vertical nets 
which had been down to 60 fathoms; it was still not 
present in the surface nets nor in the in-shore waters. 
On September 6th Mecrocalanus appeared for the first 
time in-shore, at Station IV, off the Calf Island, but only 
in the Hensen and Nansen nets which had been closed at 
5 and 15 fathoms respectively; it was not present in the 
P ,
