NOTES ON SOME OF THE SPECIES.* 



Sergestes (?) atlanticus, M. Edwards. — A single immature specimen of 

 Sergestes, which the Rev. Mr Stebbing (who examined the specimen for 

 me) thinks may probably belong to S. atlanticus, was obtained in the 

 last of the tow-net gatherings collected by.H.M.S. 'Research'; the 

 specimen measured about 18 mm. (f inch) in length. The distribution 

 of Sergestes atlanticus, according to Spence Bate — see his work on the 

 Macrura of the ' Challenger ' Expedition — is almost world-wide ; the 

 ' Challenger ' specimens were obtained in such widely divergent locali- 



* I am largely indebted to Dr Giesbrecht's valuable work, Der Pelagischen Cope- 

 poden des Golfes von Neapal, for information concerning the distribution of the Cope- 

 poda. Dr Brady's Monograph of British Copepoda, and various other works, have 

 also been consulted.
