300 TRANSACTIONS LIVERPOOL BIOLOGICAL SOCIETY. 
are, as arule, not nearly so high--the maximum this year 
being only 160 in the coarse net on April 29th at 
Station II, as compared with 560 in a fine net on 
April 16th, 1907, at Station V.. The biggest number 
caught in a fine net in 1908 was 90 on April 29th at 
Station I. Last year it was first caught (in metanauplius 
stage) on March 29th—a full fortnight earlier than this 
year. Between August 6th and September 15th, 1908, it 
was only represented by a very few specimens in six 
gatherings, while in 1907 it was represented up to 
November 8th. 
Temora longicornis again shows a_ fairly even 
distribution, being represented by small numbers (such as 
10 and 20) in nearly every net in most months of the year 
(only absent in January and December). This species is 
occasionally found in denser swarms, which accounts for 
the quite sudden larger catches that were sometimes 
obtained, such as 300 and 450 in the bay on April 21st, 
while the number on the preceding day was three only, 
and on the following day 15. In the end of May and early 
part of June there seems, however, to be a steady increase, 
from 60 on May 20th, through numbers between 200 and 
300, up to 2,000 on June 10th and 12th; after which the 
numbers fall again to 230 on the 18th and 50 on the 25tb. 
The coarse net in September obtained some large catches, 
such as 450 at Station III on September 11th, 3,000 in the 
bay on September 14th, and 2,550 at Station III on 
September 19th. Towards the end of September the 
numbers range from 100 to 300. 
Centropages hamatus is again present throughout the 
vear, with the exception of January and December. The 
uumbers are low, ranging from one to 60 only in most of 
the surface nets, both in the bay and open sea, throughout 
the year. There is no marked maximum at any point,
