Station at Millport, Cumbrae, and also in shore pools at the south-west 
corner of the island on May 6th, 1899. Professor G. 8. Brady obtainea 
the species from Cumbrae many years ago, and it is interesting to find 
it in the same localities in which it was then observed. 
Hurytemora affinis (Poppe). 
1880. Zemora affinis, Poppe, Abhandl. d. Naturw. Ver. Bremen, 
Bd. vil., pp. 55-60, Pl. IIT. 
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 Hurytemora require careful examination 
in order to distinguish the one from the other. 
Metridia lucens, 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.

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 Hast 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 Centropagide. 
Labidocera wollastont (Lubbock).

(2), vol. xx., p. 406, Pls. X.—XT. 
Last year I recorded this fine species from two Clyde stations, both oi 
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 264 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 ofthe estuary. If 
also take this opportunity to record Labidocera wollastont 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 bad not before been examined; in one collected to the east of
