VII. NOTES ON RECENT GATHERINGS OF MICRO- 

 CRUSTACEA FROM THE CLYDE AND THE MORAY 

 FIRTH. By Thomas Scott, F.L.S., Mem. Soc. Zool. de France. 



(Plates X-XIII.) 



In the following notes my remarks refer chiefly to the rarer forms that 

 have been observed in gatherings of Microcrustacea submitted for 

 examination during 1898. The gatherings examined have been collected 

 in the Moray Firth and the Firth of Clyde, and therefore the notes refer 

 chiefly to these localities. I am indebted to Mr. F. G. Pearcey, 

 naturalist on board the s.s. " Garland," for most of the gatherings 

 forwarded for examination. 



Copepoda. 



Paracalanus parvus (Ciaus). 



1863. C alarms parvus, Claus. Die frei-lebenden Copopoden, 

 p. 173, PI. XXVI., figs. 10-14; PI. XXVII., figs. 1-4. 



This Copepod, which was observed in the Firth of Clyde for the first 

 time in September 1897, has occurred in several of the tow-net gatherings 

 collected during 1898, both at the surface and bottom. It was obtained 

 at Stations IX. and XIII. in August, and at Stations VII. and VIII. in 

 September. Station XIII. is one of the Upper Loch Fyne stations, and 

 its occurrence there makes it an addition to the Loch Fyne fauna. It is 

 a small species, and may therefore have been previously passed over as a 

 young Galanus. It has also been observed in the Moray Firth and in 

 the Firth of Forth. 



*Bradyidius armatus (Brady;. 



1878. Pseudocalanus armatus, G. S. Brady, Mon. Brit. Copep., 

 vol. i., p. 46 (non P. armatus, Boeck — see Giesbrecht, Zool. 

 Anzeiger, 1897, p. 25). 

 This species is referred to because its distribution appears to be 

 somewhat restricted. Though not very plentiful, it is one of the more 

 widely diffused of the Clyde Copepoda, and it has been known for 

 many years as a Clyde species. It is usually obtained in gatherings 

 collected with the bottom tow-net, and much less frequently in surface 

 gatherings. Though the species has been recorded from the East Coast 

 of Scotland, it seems to be of rare occurrence there. I do not find a 

 single reference to it in any of the descriptions of tow-net gatherings 

 collected on the East Coast during the past year. 



Euchada norvegica, Boeck. 



1864. Euchaita prestandvece, Boeck, Overs. Norg. Kyster iagt.

 vandscopep, Forh. Vid. Selsk. Christiania, p. 40. 



I have no record of this species for the Moray Firth ; but it has, as 

 in previous years, been obtained in tow-net gatherings from various
