to add another station for it — viz., Loch Eil (off Loch Limine) — where it 

 was dredged along with Cletodes monensis and Cletodes perplexa on April 

 3rd, 1900. 



Pseudothalestris major (T. and A. Scott). 



This somewhat rare species was obtained in the store-pond of the Sea- 

 Fish Hatchery at Bay of Nigg in August, 1900. 



Cervinia bradyi, Norman. 



This interesting and well-marked species was obtained in the same 

 gathering with Cletodes monensis referred to above, collected 13 or 14 

 miles north-east of Buckie, Moray Firth, in 50 to 55 fathoms, November 

 3rd, 1900. This is the second time that Cervinia has been taken in the 

 Moray Firth ; it was taken the first time about five to seven miles off 

 Rosehearty, in 1893, and at that time it was also associated with Cletodes 

 monensis. 



Zaus goodsiri, G. S. Brady. 



This fine species was collected in 45 fathoms off Aberdeen, on 

 November 7th last year, by the Fishery steamer " Garland." The 

 gathering in which the Zaus goodsiri occurred contained a remarkable 

 assemblage of rare and interesting Crustacea ; they comprised nearly fifty 

 species, and included many genera, and nearly all the more important 

 groups were represented — viz., the Copepoda, Amphiphoda, Isopoda, 

 Sympoda, Schizopoda, and the Macrura. 



Peltidium purpureum, Philippi. 



This species was added to the British fauna in 1886 ; it was obtained 

 at Tarbert, Loch Fyne, during some investigations carried on there under 

 the direction of the Fishery Board for Scotland. Though Peltidium 

 purpureum has since that time been observed in one or two other parts of 

 Loch Fyne and the Clyde estuary, it does not appear to have been 

 recorded from any other district of Scotland. In the present paper, 

 however, I am able to add two new stations for this Peltidium, both of 

 which are on the West Coast — viz., Loch Etive, off Abbot's Island, in a 

 gathering dredged at 9 fathoms on March 30th, 1900, and in a gathering 

 collected a few days later at from 8 to 10 fathoms near the head of Loch 

 Eil (off Loch Linnhe). Both these gatherings were collected by the 

 " Garland," and forwarded to the Laboratory at Bay of Nigg. 



Alteutha purpuroeincia, Norman. 



This fine species was collected in Lerwick Harbour, Shetland, by the 

 steam trawler " St. Andrew," October 14th, 1900. Rev. A. M. Norman 

 collected this species at Hiliswick, Shetland, in 1868.* 



Idya cluthce, T. Scott. 



This species, which appears to be a deep-water form, was described in 

 1899 from specimens which had been obtained in Loch Fyne at from 50 

 to 70 fathoms, and in the Clyde at over 40 fathoms.f The same species 

 of Idya was recently observed in a tow-net gathering from the Moray Firth
