 L.M.B.C. and a past-President of the Biological Society. 

 Figure 17 shows Mr. Walker on the " Runa " searching 

 the mud brought up from the bottom of the Firth of Lorn 

 for Amphipoda. He has supplied me since with a list 

 of about 30 species of Amphipoda and Isopoda we 

 captured, including Aristias neglectus, Hansen, which we 

 had not previously found in these western waters. • 



Amongst the more interesting captures effected by 

 dredging during this Hebridean cruise was the 

 large compound Ascidian colony called " Syntethys 

 hebridicus " by Professors Edward Forbes and John 

 Goodsir, when they brought it up from 30 fathoms, off 

 the Croulin Islands, near Skye, in 1850, and described it 

 in the Transactions of the Royal Society of Edinburgh 

 the following year (vol. xx, p. 307). 



In this paper Forbes and Goodsir tell how they were 

 at the time on a yachting cruise " with our indefatigable 

 friend Mr. Mc Andrew, among the Hebrides, in the 

 month of August, 1850." This friend was Mr. Robert 

 McAndrew, a Liverpool merchant, who owned the yacht 

 " Naiad," a 70 ton yawl, which he made good use of on 

 dredging expeditions, chiefly in advancing the science of 

 Conchology. 



A few sentences quoted from the original description 

 of the " Syntethys hebridicus " dredged from Mr. 

 McAndrew' s yacht in 1850 may be of interest in 

 connection with the large specimen obtained by the 

 " Runa " this summer. Forbes and Goodsir go on to 

 say : — 



" During this voyage, which lasted three weeks, a 

 series of observations were conducted by means of the 

 dredge and the towing-net .... and our exertions were 

 amply rewarded by the discovery of several remarkable
