III. — NOTES ON THE DISTRIBUTION OF PELAGIC CRUSTACEA 

 IN LOWER AND UPPER LOCH FYNE. By Thomas Scott, 

 LL.D., F.L.S. 



The following notes on the distribution of pelagic Crustacea in Lower 

 and Upper Loch Fyne describe the results obtained by the examination of 

 numerous tow-net gatherings collected during the four years from 1905 to 

 1908, both years inclusive. 



The gatherings were collected at several fixed stations located in mid- 

 channel, two of them being situated in Lower Loch Fyne and the others 

 in the upper portion of the loch. 



The outermost station in Lower Loch Fyne (Stat. I.) is situated in mid- 

 channel and nearly due east of the north end of Barmore Peninsula, and 

 the other (Stat II.) nearly midway between Maol Dubh Point on the west 

 and Kilfinan Bay on the east side of the loch. Those in Upper Loch Fyne 

 are arranged as follows : — Station III. is distant fully one mile and almost 

 directly south-east of the village of North Karnes ; Station IV. is about 

 three-quarters of a mile south-east of Kilmichael Beg ; Station V. is mid- 

 way between Pennimore on the west and Newton Bay on the east side of 

 the loch ; while Station VI. is situated off the mouth of the Douglas 

 Water and distant north by east from Strachur about a mile. 



Nearly six hundred gatherings have been collected during the four 

 years. A small proportion of them (and nearly all in the first year) con- 

 sisted of horizontal hauls ; the others were vertical — that is, the net was 

 lowered to the depth required and then hauled straight up. The gatherings 

 are from various depths, regulated by the depth of water at the station 

 where they were collected. At the deep-water stations, i.e., the two in 

 Lower Loch Fyne and Stations v. and vi. in the Upper Loch, a horizontal 

 gathering was collected in the first year at or near the surface, and others 

 at mid-water and bottom, while the vertical hauls were usually taken at 

 intervals of fifteen fathoms, beginning at fifteen fathoms from the surface, 

 down to sixty fathoms, and also one from the bottom if the depth was 

 much over sixty fathoms. 



The following is a tabulated list of the Stations, giving the number of 

 gatherings, horizontal and vertical, collected at each of them during each 

 of the four years : —
