 Raia batis, L. (common skate), fished principally in the winter and from 

 the West Loch and Sound of Gigha. 

 „ clavata, L. (thornback ray), frequent during the winter fishing. 

 The above are all the species of fishes that have come under our notice 

 at Tarbert during the past year ; there are doubtless many more still to be 

 recorded. The list of Elasmobranchs is very imperfect, no special atten- 

 tion having been given to this group.
