Part III. — Eighth Annual Report 
in the surface- and in the bottom-nets, rarely being captured in mid-water. 
This feature in the habit of the Copepods may be associated with the 
presence of other forms of pelagic life, in the midst of which Halitemora 
finds suitable nourishment. It is very plentiful in autumn, and some- 
what later. 
Centropages hamatus, Lilljeborg. 
Bottom-Tow-Net. 
First Appearance. — 28th June, numerous. 
Last appearance. — 30th October. This form is not so common as 
Acartia longiremis or Halitemora longicoris, but still occurred 
frequently in this net. 
Surface- Tow-Net. 
First appearance. — 26th April, numerous. 
Last appearance. — 26th September. Between the two dates above men- 
tioned this species was often procured-^more frequently indeed 
than in the bottom-tow-net. 
Centropages hamatus is found in the Bay throughout the greater part 
of the year, especially from April to August, and like others is more fre- 
quently met with in the surface and bottom-nets than in the mid-water. 
It ranges, according to Prof. Brady, from the tidal rocks to the opun 
ocean. 
Centropages typicus, Kroyer. 
Bottom-Tow-Net. 
This form appeared first on the 14th of August, in St Andrews Bay, but 
on the 10th of that month it was found 15 miles S.E. of the Isle of May. 
During the remainder of the month it occurred once or twice. 
Surface-Tow- Net. 
Only on the 30th of August and 8th September was C. typicus found 
in this net. 
It is noteworthy that this species occurred less frequently than the fore- 
going (C. hamatus), and was later in its appearance this season. Accord- 
ing to Prof. Brady it is one of the most abundant Copepods in the British 
Seas, and ranges to the North Sea and the Atlantic. 
Longipedia coronata, Claus. 
Bottom-Tow-Net. 
First appearance. — 14th July. 
Last appearance. — 18th October. 
Most plentiful. — In the latter half of July, in September, and during the 
first half of October, many, as a rule, each time. It occurred fre- 
quently during the period mentioned above. 
Surface-Net. 
First appeared on 23rd July, then on 26th and 31st, three times at end 
of August, on 5th and 26th September many, and on 17th October. 
Anomalocera patersonii, Templetcn. 
Found in the bottom-net on the 9th August, 15 miles E.S.E. of Bell 
Rock. 
The species is easily recognized by its fine bluish coloration and other 
features. It appears to keep to the open water, but it may yet be found 
within the Bay. It is stated by Brady to be generally distributed over 
the North Sea, and extends to the Mediterranean.
