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.E.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 JSTewhaven ; and (4.) 

 dredging excursions, in both sailing boats and steamers, 

 organised in connection with the University Class of Practical 

 Zoology.
