251 Part III. — 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. Isias 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 in various parts of the Clyde, it seems to be always a scarce species. 

 The following are a few of the more recent records of Isias 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. 



* Eurytemora lacinulata (Fischer). 



1853. Cyclopsina lacinulata, Fischer, Beitr. z. Kenntn. d. Cyclo- 

 piden, Bull. Soc. Imp. Natur., Moscow, XXVI., p. 86-90, 

 PJ. II., figs. 4-17, 34. 



This species has been obtained during the past year in brackish water- 

 pools at Hunterston, Firth of Clyde. Eurytemora 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, PI. VIII., 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, PI. VIII. 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 wollastoni, Lubbock, Ann. and Mag. Nat. Hist. 

 (2), vol. xx., p. 406, PI. X. fig. 13 ; and PI. XL 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).
