OF THE FIRTH OF FORTH. 5 
mostly collected by Dr M‘Bain himself and by Dr Howden, 
but some attention was also paid to the literature of the 
subject. The authority of this list will frequently be used 
in our paper. 
We are especially indebted, and would now tender our best 
thanks, to Mr F. M. Balfour, F.R.S., Fellow and Lecturer of 
Trinity College, Cambridge, who has very liberally given us 
lists of the rarer forms which he has dredged in the Forth. 
Mr Balfour’s assistance is the more valuable, as his work has 
principally been done in a part of the estuary which we have 
had comparatively little opportunity of investigating. 
Dr M‘Intosh’s excellent “ Marine Invertebrates and Fishes 
of St Andrews” should be consulted by students of the 
local fauna. From the proximity of the locality investigated, 
this work is very interesting in connection with the fauna of 
the Forth. 
In addition to a study of the somewhat voluminous 
but scattered literature of the subject, our opportunities of 
acquiring a knowledge of the fauna of the Forth have con- 
sisted in—(1.) shore-collecting, extending over several years, 
at many points on both sides of the Firth; (2.) collecting 
from the refuse of the fishing boats at Newhaven and other 
piers; (3.) occasional night excursions with the oyster 
dredgers and long-line fishermen from Newhaven; and (4.) 
dredging excursions, in both sailing boats and steamers, 
organised in connection with the University Class of Practical 
Zoology.
