25 6 ANNALS OF SCOTTISH NATURAL HISTORY 



puzzling group, have received much attention from Mr. Regan, and 

 we accept the results of his investigations and opinions regarding 

 them with confidence. The chapters devoted to them form a most 

 important and interesting and authoritative contribution. The 

 accounts of the rest of the species, and the results of recent 

 researches into their life-histories, are excellent, and the author is to 

 be congratulated on the interesting manner in which he has treated 

 his subject. There are also valuable chapters devoted to Classifica- 

 tion and Taxonomy, while one on the Origin and Geographical 

 Distribution of the various species, with special reference to the 

 racial forms peculiar to our islands, forms a fitting conclusion to 

 an admirable book. The volume is adequately illustrated by no 

 less than 37 excellent plates and numerous test figures drawn by 

 the author, all of which are most helpful adjuncts to the letter- 

 press. 



WILD BIRDS AT HOME (Fifth Series). Sixty photos from life by 

 Arthur Brook, of " British Birds and their Nests." With notes by 

 George Girdwood. London and Glasgow : Gowans and Gray, 1911. 

 Price 6d. 



This little book is composed of a remarkably fine series of 

 photographs depicting the life and habits of various British birds. 

 To each portrait is affixed the name of the bird in English, French, 

 German, and Latin, whilst an Appendix affords notes in which the 

 characteristic ways and habits of the different birds are briefly but 

 clearly described. This is the fifth series of the " Wild Birds at 

 Home," a series which deserves to be popular as a unique collection 

 of bird photographs en miniature. G. E. G.-M. 



A MONOGRAPH OF THE BRITISH ANNELIDS. Vol. II. Part II. 

 Polychaeta: Syllidas to Ariciidee. Pp. 233-524; Plates li.-lvi. 

 coloured, and Ixxi.-lxxxvii. uncoloured. By Prof. W. C. MTntosh, 

 M.D., F.R.S., etc. Ray Society, 1910. 



In the July 1908 number of the "Annals" we took notice of 

 Part I. of the second volume of Prof. MTntosh's monumental work. 

 We have now to chronicle the issue of Part II. of that volume. 

 About 70 species, belonging to the Families Syllidse, Nereidae, 

 Eunicidas, Goniadidae, Glyceridae, and Ariciida?, are therein described 

 and illustrated. Of the beautiful coloured plates, on which some- 

 thing like one-half of the species are figured, it is impossible to 

 speak too highly. An Index to the species, etc., described in Vol. I. 

 is inserted at the end of the part. W. E.
