numbers were not heh until the middle of April, when 
the maximum of 30,000 was reached on April 18th, as 
compared with the maximum of 10,450 on April 15th in 
1907. From this time until their disappearance at the 
end of April, the numbers were higher for 1908 than for 
1907. On the other hand, the “ Cypris” stage was not 
lieatly sO well represented in 1908 as in 1907, the 
maximum being reached on April 29th with 42, as 
compared with 2 maximum of over 1,/00 on April Ldth 
last year. In both years this form does not appear after 
the last week in May. On the whole then, here, as in 
other groups, the piesent season was a late one; and it 
looks as if there hac been an unusually severe mortality, 
as although the Naupliu were abundant in the middle of 
April, very few of the animais were found in _ the 
be \ ie tr { © ‘ 
Cypris ’ stage later on.

The numbers for Sagztta in the bay in the first half 
of the year keep at a fairly constant but low value (30 or 
under) until May 28th (70); and then throughout June 
they fall and then rise to much the same level (26, 43, 
33, 48, 65, 69). After some sudden rises and falls in 
July and August the numbers diminish until on August 
28th and 29th Sagrtta is entirely absent. In the open 
sea, the maximum is in August, when we have 98 and 
150 on August Gth, 120 and 256 on August 7th, L111 on 
August 12th, 76 on August 15th, 52 on August 19th, and 
87 on August 22nd. ‘The numbers rise as a general rule 
higher than those of the bay, and, as would be expected, 
the * pulley “ net and the “ coarse’ net catch more than 
the others. 
The biggest catch in the bay was on September 
‘4th, 220 in a coarse net, only 10 in the fine. Throughout
