806 TRANSACTIONS LIVERPOOL BLOLOGICAL SOCIETY, 
September and October, when Sagztta does occur, there 
are generally more in the coarse net than in the fine; 
but after September 24th the numbers are low, the highest 
being 11, until November (th, when we find 108 (¢.), 
November 10th 84 (c.), then 29, 17, 18, 7, 30, 18 (all 
coarse nets), the fine nets in each case catching five or 
under. 
Comparing these results with those of 1907, we see 
that the numbers are lower throughout the present year. 
The maximum in the bay gatherings (220 on September 
14th) is a month later than the much higher maximum 
(1,800) of 1907; but the maximum in the open sea was 
in August (256 in coarse surface net on August 7th, at 
two miles N.W. of Bradda Head). In both years the 
numbers fell after the maximum, and rose again in the 
first week of November, to 324 in 1907, and to 108 in 
1908. 
On the whole, the statement made last year that— 
‘ Sagitta is present throughout the year; it is most 
abundant in August, and the minimum occurs in winter 
(January to March),” still holds, with the qualification 
that in 1908 the numbers are lower and the maxima are 
later. 
Tomopterts onisciformis occurs, in small numbers 
only, from February 6th to December 30th. It is 
probably present in our area throughout the year, and its 
non-appearance in the records for certain months 
(January, March, May and July) can probably be 
explained by the net having failed to capture a species 
represented by such small numbers. ‘The only larger 
numbers are apparently exceptional occurrences, such as 
when the shear net caught 200 at Station I on August 7th 
and 120 at Station I on September 15th, and when the 
coarse net caught 65 in the bay on October (th.
