Part III. — Eighteenth Annual Report 



it has again been observed in several of the gatherings sent to the Fishery 

 Board's Laboratory from the Clyde. In 1897 a new genus was instituted 

 for this copepod by Dr. W. Giesbrecht, of Naples, but it appears to be 

 one of those species whose lot it is to undergo several removals ere it 

 reaches its ultimate destination, as indicated by the following quotation 

 from a work lately published by Herr. 0. Nordgaard, entitled, " Report 

 on Norwegian Marine Investigations, 1895-97." At page 21 of his 

 report, Herr. Nordgaard refers to the species under consideration as 

 follows : — 



" In 1 Undersogelser over Dyrelivet i Arktiske Fjorde ' Herr Sparre 

 Schneider has mentioned a copepod that is called Undinopsis bradyi, G. 

 0. Sars. This species is said to have been found in Kvsenangen and at 

 Tromsb. In the summer of 1897 I showed Professor Sars a preparation 

 of a copepod that I was unable to identify. He then declared it to be 

 the very Undinopsis bradyi, and afterwards informed me in a letter that 

 the said copepod had been described by Mr. Brady (Monograph of the 

 Copepoda of the British Islands, i., p. 46, PI. IV., figs. 1-11). 



The species was, however, there wrongly identified with Pseudocalanus 

 armatus, Boeck, which, according to Mr. Sars, is another species. As 

 Mr. Sars in his gigantic revision of Norwegian Crustacea will soon come 

 to the Copepoda, I shall do nothing but here note the occurrence of 

 Undinopsis bradyi at the following places : — 



March 14th, 1896, Vestfjord (67° 32'5' N. ; 130° 24-5' E.) in 

 Plankton 0'200m. 



March 5th, 1897 ; Ostnes-fjord in Lofoten. 



March 7th, 1897, Irold-fjord in Lofoten, Plankton 0'65m. 

 Besides, I have this year (1899) taken several specimens of the species in 

 fjords near Bergen." 



This note by Herr. Nordgaard is of interest, if for nothing else than 

 the information he gives concerning the distribution of the species, 

 but it also indicates that Professor Sars' designation is likely to take 

 precedence over that of Bradyidius armatus of Drs. Giesbrecht and 

 Vanhofen. It is doubtful, however, if this copepod will be allowed to 

 rest under Undinopsis bradyi, for it is by no means a rare species, aud, as 

 Herr. Nordgaard and Professor Sars have shown, it has a wide distribu- 

 tion. It is probable, therefore, that it has not escaped the notice of some 

 of the earlier naturalists, and may be described and named in their 

 published works by a designation different from any of those referred to.

This, which is a moderately rare species, has again been observed in 

 several of the tow-net gatherings forwarded from the Clyde during recent 

 months. The specimens obtained were found for the most part in 

 gatherings collected in the tow-net fixed to the head of the trawl, and 

 appeared to be most frequent in the gatherings collected in September. 

 The species was taken in Kilbrennan Sound at Stations III. and IV., 

 near Sanda Island, and in the vicinity of Ailsa Craig. I have no records 

 of Isias from Loch Fyne this year. It may be of interest to mention that 

 it was also during September last year that Isias was chiefly observed.
