92 ME. THOMAS SCOTT ON THE 



Brady (1878) : the latter is recognized as a distinct species by 

 Giesbrecht under the name of Metridia Mhernica (Brady & 

 Robertson, 1873).] 



Family Misopheiad^. 



Genus Misopheia, Boeck, 1864 



MiSOPHEIA PALLIDA, Boeck. 



1864. Misophria pallida, Boeck (5), p. 24. 



One or two specimens of this species were obtained in a 

 gathering o£ micro-crustacea dredged at West Bay, Cape Plorp, 

 in 2 to 10 fathoms on July 2nd, 1897. Misophria pallida has 

 been recorded from Norway, and it appears to be generally 

 distributed around the British coast, but to be nowhere very 

 common. In Scotland it has been obtained in the Firth of Forth, 

 in Moray Firth, and in the Firth of Clyde. 



Family CTCLOPiDiE. 

 Grenus Oithona, Baird, 1843. 



OiTHONA siMiLis, Claus. (PI. 4. figs. 18, 19.) 



1866. Oithona similis, Clsiws {2,'i). 



This species was obtained in tow-nefc gatherings collected two- 

 thirds of a mile south-west of Elmwood on May 22nd, 1897, but 

 was comparatively scarce ; and it was taken with the tow-net in 

 the same neighbourhood during the following month. This is 

 certainly the Oithona similis, Claus, as described and figured by 

 Dr. Giesbrecht in ' Pelagischen Copepoden des Grolfes von 

 Nfapel.' The same author refers doubtfully to this species the 

 Oithona helgolandica^ Claus (1863), and the Oithona spinifrons, 

 Boeck (1864) ; and with respect to Oithona spinifrons, 'BoecV, 

 Prof. Brady, in his 'Monograph of the British Copepoda,' vol. i. 

 published 20 years ago, states that he is " not at all satisfied that 

 this is not synonymous with 0. helgolandica, Claus." As there 

 appears to be a consensus of opinion that all three species are 

 synonymous, it would be better if the earlier name — O. helgo- 

 landica — of Claus were adopted. Oithona spinirostris, Claua 

 (1863), is regarded by Dr. Griesbrecht as synonymous with 

 0. plumifera, Baird (1843).
