This fine species was frequent in a tow-net gatbering collected on the 

 19th October, 1900, in 80 to 85 fathoms, about fifty miles S.S.E. of Fair 

 Island, between Orkney and Shetland. The tow-net had touched bottom, 

 and when hauled up was found to contain a considerable quantity of 

 mud, this was washed through the net and the material that remained in 

 the net was preserved; mixed up in this material was a considerable 

 number of Macrocypris. In the Monograph of the Marine and Fresh- 

 water Ostracoda of the North Atlantic and North- Western Europe, the 

 authors, referring to Macrocypris minna, say (op. cit., p. 117) that "the only 

 British locality for this species is Shetland, where a single specimen was 

 dredged by Mac Andrew forty years ago, and a second by A. M. N. on the 

 outer Haaf in 1861."

A single perfect specimen and a valve of this species were obtained in 

 the same material with the last ; Cythereila abyssorum seems to be a rare 

 species in our seas, as the only Scottish record for it hitherto appears to 

 be that of G. S. Brady, who, in his "Monograph of Recent British 

 Ostracoda," states that two or three specimens were obtained by himself 

 and the Rev. A. M. Norman amongst sand dredged by Mr. Jeffreys in 60 

 fathoms in the Minch.* 



It may be mentioned in passing that the Foraminif er Saccamina sphcera 

 was very common in this gathering ; a few other Foraminif era, such as 

 Astrorhiza arenaria, Psammosphcera fusca, and Placopsilina bulla, were 

 also observed.
