ZOOLOGICAL NOTES 259 



in 1867 by Mr. David Robertson, F.L.S., but was not recorded 

 till after its discovery in Sutherland. These two localities were the 

 only British habitats known to me previous to my visit to Barra in 

 May last ; it was therefore interesting to find that this was the only 

 Diaptomns in the gatherings from the various Barra and North Uist 

 lochs examined. Diaptomns serricornis was obtained in nearly all 

 of the lochs visited, and was quite a common species in some of 

 them. THOMAS SCOTT, Leith. 



Neomysis (Mysis) vulgaris, J. V. Thompson, in Barra, Outer 

 Hebrides. Neomysis vulgaris was common both in Sinclair Loch 

 and in Loch Dorlinn two small neighbouring lochs on the west 

 side of Barra. A small stream from Sinclair Loch, joined by a 

 branch from Loch Dorlinn, carries the overflow water of both 

 lochs to the sea. Both lochs are not much above the high-water 

 level of the sea, and it is reported that sometimes during very high 

 spring tides the sea flows into them. Whether that be the case or 

 not, the water in Sinclair Loch was quite fresh at the time of my 

 visit. I and Mr. Robert Duthie, Fishery Officer, who assisted me 

 to examine these and other Barra Lochs, tasted the water and found 

 it pleasant and free from any trace of brackishness. It has been 

 considered that this Schizopod does not live in fresh water, but 

 requires the water to be more or less brackish ; its occurrence in 

 these Barra lochs where the water was quite fresh is therefore of 

 interest. It may also be of interest to state that Neomysis vulgaris 

 was quite common in a fresh-water loch near Wick in 1891 (see 

 remarks in " Ninth Annual Report of the Fishery Board for Scotland," 

 part iii. p. 285). The water of the Wick loch was tested with one 

 of our improved hydrometers and found to be as fresh as the water 

 hat was being used for domestic purposes. T. SCOTT, Leith.
