All localities given for the species of Copepoda in the 

 following list are those where the species has been collected 

 by A. M. N., unless the name of another carcinologist is 

 given. 



Tribe I. CALANOIDA. 



The Copepoda in this tribe are arranged as in A 7 ol. iv. of 

 Sars's ' Crustacea of Norway ' mentioned above.

 CALANUS SEPTENTRIONALIS (H. Goodsir). 



1843. Cetochilus septentrionalis, H. Goodsir, Edinburgh New Philos. 



Journ. vol. xxxv. p. 336, pi. vi. figs. 1-11. 



1863. Cetochilus helgolandicus, Claus, p. 171, pi. xxvi. figs. 2-9. 

 1901. Calanus helgolandicus, G. O. Sars, p. 11, pi. iv. 



Frequent in tow-net gatherings from Plymouth, Salcornbe, 

 Fulmouth, and the Scilly Isles. 



The Calanus so common round the British coasts is perhaps, 

 as Sars regards it, a species distinct from C. finmarchicus of 

 Gunner, and it is the form named by Dr. Claus C. helgo- 

 landicus ; but Goodsir long before had described the Calanus 

 which is abundant in the Firth of Forth, and is identical 

 with the Heligoland form, under the name CetocMlus septen- 

 trionalis, and his figures so far as they go agree with that form 

 rather than with C. finmarchicMs, and his name must therefore 

 be employed. Sars has made C. septentrionalis a synonym 

 of C. jinmarr.Mcus, but the locality whence the former was 

 procured, and the form of the animal as seen from above 

 given by Goodsir, clearly show that it was the same asi 

 C. helgolandicus.
