Sea-Eagles in Argyll. On the 12th of April, whilst rounding 

 Ardnamurchan Point on one of the mail steamers, I observed a 

 pair of Sea-Eagles {Halicctus albicilld). It would be interesting to 

 know if these birds have again taken up their abode at this old 

 resort for nesting purposes or not. In former years a pair did 

 breed there regularly, till they were finally destroyed. F. S. 

 Beveridge, Lochmaddy. 



Pandarus bicolor, Leach, in " Forth." As this species is not 

 included in Dr Thomas Scott's Catalogue of Forth Crustacea, and 

 no occurrence from the area' is given in the recently issued Ray 

 Society vols, on " British Parasitic Copepoda " by Dr Scott and 

 Mr Andrew Scott, the fact that I have a specimen an adult 

 female which was taken from a dogfish captured off North Berwick 

 in August 1912, seems worth placing on record. William Evans.

The Food of Some British Wild Birds : A Study in Economic 

 Ornithology. By Walter E. Collinge, M.Sc, F.L.S., etc. London : 

 Dulan & Co., 1913, pp. vi. and 109. Price 4s. 



This is a useful contribution to a subject of considerable interest to 

 naturalists and importance to agriculturists, horticulturists, and fruit- 

 growers. In addition to the original contributions on the part of the 

 author, we have the results (published) of the researches of a number of 

 other workers who have also made special studies in the subject. The 

 book is divided into the following sections : Introduction, Historical 

 Review, Methods of Examination, Economic Importance of Birds, List 

 of Birds Examined (twenty-nine species), Birds as Destroyers and 

 Distributors of Weed Seeds, Birds in Relation to Forestry, Legislation, 

 Protective Measures, Summary and Conclusion, Bibliography. The 

 results under the section of birds examined, form the main contribution. 

 Here we have collected under each of the selected species the author's 

 post-mortem records, the investigations of others, field observations, and 

 the conclusions to which Mr Collinge has come to regarding the birds' 

 utility or harmfulness. With these verdicts we do not always agree, and 

 prefer in cases to fall back upon the excellent Scotch finding of "not 

 proven." The book is to be commended, and will, we trust, be the fore- 

 runner of future enlarged editions.
