TROPICAL PLANKTON. 288 
Anomalocera patersont, Templeton. 
1837. Anomalocera, Trans. Entom. Soc., Lond., vol. II., p. 34. 
This large, well-known, beautiful Copepod is a distinctly 
northern form, commonly met with round the British 
Isles and about the Norwegian coasts, and reported 
between Faeroe and Greenland. 
Gibraltar has hitherto been its most southerly recorded - 
limit, and it was therefore with some surprise that I found 
a specimen in No. 1, Wyse collection, taken near the 
southern extremity of Africa, which greatly extends its 
range of distribution. 
Pontellopsis regalis, Dana. 
1849. Pontella regalis, Dana, Proc. Amer. Acad., vol. II., p. 31. 
Found in No 14, Wyse only, in the Bay of Bengal, 
about its most northerly recorded limit in the Indian 
Ocean. It has been recorded also from the Mediterranean 
and the Atlantic Ocean. 
Pontellina plumata, Dana. 
1849. Pontella plumata, Dana, Proc. Amer. Acad., vol. II., p. 27. 
Found sparingly in both collections in the Indian Ocean 
and Mediterranean, both previously recorded habitats. 
Acartia claust, Giesbrecht. 
1863. Dias longiremis, Claus, Freileb. Cop., p. 1938, Pl. XXXIII. 
This is one of the commonest northern species, abundant 
round the British Isles. It was found in fair quantity at 
13 out of the 23 Wyse stations, and at 8 stations in the 
Herdman collection. Its range of distribution therefore 
extends from South Africa, through the Indian Ocean into 
the Bay of Bengal, and up the Red Sea. It requires 
careful dissection to distinguish it from A. longiremis, 
Lilljeborg, and it is quite possible that some of the latter 
may have been present, although all I dissected were of 
the former species.
