251 Part I11.—-Seventeenth Annual Report 
Moray Firth collected during May and June last year, both species were 
nearly equally frequent, Centropages hamatus, however, was even here 
rather the more common of the two species. 
Isias clavipes, Boeck. 
1864. Jsias clavipes, Boeck. Overs. Norg. Copep., Forh. Vid. 
Selsk, Christiania, p. 18. 
This fine species has been obtained in several of the Clyde tow-net 
gatherings, both surface and bottom. But though occurring now and 
again 1n various parts of the Clyde, it seems to be always a scarce species. 
The following are a few of the more recent records of /séas from the 
Clyde—at Station II. (Kilbrennan Sound), in surface and bottom tow- 
nets, at Station XII. (between Arran and the Heads of Ayr), in the 
bottom tow-net in August, and in the surface tow-net at Station VII. in 
September 1898. 
*Hurytemora lacinulata (Fischer). 
1853. Cyclopsina lacinulata, Fischer, Beitr. z. Kenntn. d. Cyclo- 
piden, Bull. Soc. Imp. Natur., Moscow, XXVI., p. 86-90, 
P]. IL. figs. 4-17, 34. 
This species has been obtained during the past year in brackish water- 
pools at Hunterston, Firth of Clyde. Hurytemora lacinulata has been 
recorded from the Clyde district on one or two former occasions, but not 
previously from Hunterston. 
* Metridia hibernica (Brady and Robertson). 
1873. Paracalanus hibernicus, Brady and Robertson, Ann. and 
Mag. Nat. Hist. (4), vol. xii, p. 126, Pl. VIIL., figs. 1-3. 
This species has already been recorded from Loch Fyne, and seems to 
be distributed, though very sparingly, all over the Clyde estuary. 
Metridia hibernica somewhat resembles Metridia longa (Lubbock), but is 
smaller than that species. It may be difficult to discriminate between 
the young of the two species; but there need be little difficulty in 
distinguishing the adult forms, especially if males are present. Metridia 
hibernica has also been observed both in the Moray Firth and in the Firth 
of Forth. 
*Candace pectinata, Brady. 
1878. Candace pectinata, Brady, Mon. Brit. Copep., vol. i. p. 
49, Pl. VILI. figs. 14,15; Pl. X. figs. 1-12. 
Though this species has been obtained both in the Firth of Clyde and 
the Moray Firth, as well as in the Firth of Forth, it has not been observed 
within recent months. 
Labidocera wollastoni (Lubbock). 
1857. Pontella wollastonit, Lubbock, Ann. and Mag. Nat. Hist. 
(2), vol. xx., p. 406, PI. X. fig. 13 ; and Pl. XI. figs. 9-11, 18. 
The only records of ,this species I have for the past year are two, 
and both are for the Clyde. They are as follows: --In a bottom tow-net 
gathering collected at Station IX. on August 31st, rare; and in a surface 
gathering collected at Station VIII. on September 23rd (only one specimen 
was observed in this gathering).
