Part III. — Seventeenth Annual Report 



Anomalocera patersonii, Templeton. 



1837. Anomalocera patersonii, Templeton, Trans. Entoni. Soc, 

 vol. ii. p. 35, PL V., figs. 1-3. 



This species, which is one of the most richly coloured of the British 

 Copepocla, was occasionally observed during the past year in tow-net 

 gatherings both from the Firth of Clyde and the Moray Firth, but it 

 seldom occurred in any quantity. 



Parapontella brevicornis (Lubbock). 



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

 (2), vol. xx., PI. XL, figs. 4-8. 



Though Parapontella. may occasionally be found moderately common 

 more frequently one or a few specimens only are obtained in any single 

 gathering — such, at least, is my experience in regard to the distribution 

 of this species in the Scottish seas. Parapontella brevicornis has during 

 the past year occurred sparingly both in the Firth of Clyde and in the 

 Moray Firth. Living specimens are readily distinguished, even amongst 

 crowds of Calanus, Pseudocalanus, Temora, etc., by their peculiar dark 

 or blackish colour, but much of this colour is lost when the specimens 

 are preserved in spirit. 



Acartia clausii, Giesbrecht. 



1889. Acartia clausii, Giesbrecht, Rendiconti R. Accad. d. Lincei, 

 vol. v., fasc. 11. 



This is the only species of Acartia I have hitherto observed in the 

 Clyde district. The spines, with which the fifth pair of feet of the female 

 are armed, are short and very stout, and therefore very different from 

 those of Acartia longiremis, Lilljeborg. In the Moray Firth district both 

 Acartia clausii and Acartia longiremis are met with ; the first is frequent 

 in the open sea, but it has also been observed inshore. On June 6th, 

 1898, both species occurred in a gathering collected at Station III. 

 (Cromarty Firth), where there is usually a more or less admixture of fresh 

 water, and also at Stations I. and II. (off the Nairn Coast) on the 7th 

 of the same month. Neither Acartia bifilosus, Giesbrecht, nor Acartia 

 discaudata, Giesbrecht, have been observed in the Moray Firth district, 

 but it is quite possible that they may yet be found there — especially in 

 that part of the district known as the Beauly and Cromarty Firths, where 

 the conditions seem to be favourable for these two species. 



Cervinia bradyi, Norman. 



1878. Cervinia bradyi, Norman; Brady, Mon. Brit. Copep., 

 vol. i., p. 86, PL XXIVa., figs. 3-13. 



A single specimen of this curious species was obtained in a small 

 gathering of Microcrustacea washed from a quantity of mud brought up 

 in the bottom tow-net at Station XII. (Firth of Clyde) on 29th August 

 1898, from a depth of from forty to forty-three fathoms. Cervinia was 

 discovered at Oban by the Rev. A. M. Norman in 1877. It has also been 

 recorded from the Irish Sea by I. C. Thompson, of Liverpool ; but this 

 appears to be the fir^t time the species has been observed in the Clyde. 

 It is quite distinct from any other species of the British Copepoda.
