120 ANNALS OF SCOTTISH NATURAL HISTORY 



published a note referring to its occurrence, along with Rhinca- 

 lanus gigas, Brady, in the Moray Firth. In the note on the species 

 in the Fishery Board's Report referred to I described briefly its 

 distribution, which, so far as known, seems to be tropical or 

 subtropical. It is very interesting, therefore, to find these appear- 

 ances of this Eucalanus in the regions mentioned. The recurrence 

 of Eucalanus crassiis in the Moray Firth last year is a further 

 evidence of the extensive distribution of the species, whether brought 

 about by currents or otherwise. The specimens referred to in the 

 previous Moray Firth record were captured off Nairn ; and on the 

 present occasion the specimens three in number were taken a 

 little to the west and south of Golspie. In the female of this 

 species the abdomen is very short, and the first abdominal segment 

 much dilated ; in the male two short setae project at an obtuse 

 angle and spring from the posterior edge on each side of the 

 second-last thoracic segment. No other Eucalanus possesses this 

 character. THOMAS SCOTT, Leith. 



On the recurrence of Labidoeera wollastoni, Lubbock, and 

 Isias elavipes, Boeck, in the Firth of Clyde. I recorded these two 

 species of Copepoda for the Firth of Clyde in 1896, in the "Trans- 

 actions of the Royal Physical Society of Edinburgh " (vol. xiii. p. 1 74). 

 Isias had been previously recorded for Scotland in 1878 by Dr. 

 G. S. Brady in the " Monograph of British Copepoda " (vol. i. 

 p. 64, and figure), but that was the first time Labidoeera had been 

 recorded from the Scottish seas. They are both well marked species, 

 and do not appear to be very common. They were obtained last 

 year in tow-net gatherings collected near the seaward limits of the 

 Clyde estuary. On the previous occasion they were both found 

 in some material collected in Machrie Bay, Arran. Dr. Brady's 

 Clyde record of Isias is for Cumbrae. THOMAS SCOTT, Leith. 



Paraealanus parvus, Boeck, in the Firth of Clyde. This is a 

 small but distinct species, and one that seems to be widely distri- 

 buted. It was common in a gathering of Entomostraca collected a 

 few years ago at the mouth of the Firth of Forth, and has also been 

 observed in one or two other places off the coast of Scotland, but 

 has not before been recorded from the Clyde. The Clyde tow-net 

 gatherings in which it was obtained were made in September last 

 year : one in Kilbrennan Sound and the other one from the vicinity 

 of Ayr Bay. It has also been taken near the Bass Rock. Probably 

 it may have been passed over previously as a young Calanus.
