385 Part III. — Eighteenth Annual Report 



Station at Millport, Cumbrae, and also in shore pools at the south-west 

 corner of the island on May 6th, 1899. Professor G. S. Brady obtained 

 the species from Cumbrae many years ago, and it is interesting to find 

 it in the same localities in which it was then observed. 



Eurytemora afflnis (Poppe). 



1880. Temora affinis, Poppe, Abhandl. d. Naturw. Ver. Bremen, 

 Bd. vii., pp. 55-60, PL III. 



I find this species in rock pools near low-water mark at Bay of Nigg, 

 Aberdeen (just in front of the New Laboratory of the Fishery Board for 

 Scotland), where it is not uncommon. It also occurred in a large pool 

 left by the ebbing tide near the bridge where the railway crosses the 

 River Dee. These species of Eurytemora require careful examination 

 in order to distinguish the one from the other. 



Metridia hicens, Boeck. 



1864. Metridia lucens, Boeck, Forh. Vid. Selsk., Christiania, 

 p. 14. 



This species was moderately frequent in a bottom tow-net gathering of 

 Crustacea collected during the past year in Aberdeen Bay, In the Firth 

 of Clyde, Metridia lucens appears to be one of the resident copepods, as 

 it may be obtained there all the year round, though usually in small 

 numbers. The more recent Clyde gatherings in which the species occurred, 

 and of which I have notes, were collected in the bottom tow-net near the 

 seaward part of the estuary. 



Paramesophria cluthce, Th. Scott. 



1897. Paramesophria cluthai, Th. Scott, Fifteenth Rep, Fish. 

 Board Scoil, Part III., p. 147, PI. II., figs. 3-8; PI. III., 

 figs. 13-16. 



This moderately large and distinct species was described from specimens 

 dredged off Largabruach, Upper Loch Fyne, and I have now to record 

 its occurrence at Tarbert Bank (off East Tarbert), Lower Loch Fyne ; it 

 was obtained amongst some material dredged from about 17 to 20 fathoms 

 on October 21st, 1899. In one of the more recently published works on 

 the Copepoda (Das Tierreich, Lief. 6), Paramesophria takes its place 

 amongst the Centropagidse. 



Labidocera ivollastoni (Lubbock). 



1857. Pontella wollastoni, Lubbock, Ann. and Mag. Nat. Hist. 

 (2), vol. xx., p. 406, Pis. X.-XL 



Last year I recorded this fine species from two Clyde stations, both of 

 which are near the seaward limits of the estuary. This year I have to 

 record its occurrence in a bottom tow-net gathering (12 to 26|- fathoms), 

 collected in the vicinity of Sanda Island, near the mouth of the Clyde, on 

 September 5th, 1899 ; it was also obtained in a second gathering collected 

 two days later in about 55 fathoms and somewhat further seaward. In 

 a gathering collected in November a number both of males and females 

 were found. This gathering was also from the mouth of the estuary. I 

 also take this opportunity to record Labidocera ivollastoni from the Firth 

 of Forth. During the past summer I overhauled some tow-net gatherings 

 that had been collected a few years ago, and found that one or two of 

 them had not before been examined; in one collected to the east of
