62 ANNALS OF SCOTTISH NATURAL HISTORY 



cucumbers, we observe, are placed beside the Sea-urchins in the 

 sub-Phylum Eleutherozoa ; and most of the British species of 

 Echinoderm, it should be said, are mentioned in their proper places. 

 The volume is, like the rest of the series, well illustrated, a 

 number of the figures being original. W. E. 



THE RECREATIONS OF A NATURALIST. By James Edmund 

 Harting. With Eighty-one Illustrations. London : T. Fisher Unwin, 

 1906. 



Mr. Harting, who is so well and so favourably known to all 

 field-naturalists, has for many years past contributed articles of con- 

 siderable interest to zoologists and sportsmen to various magazines, 

 through whose pages they are scattered far and wide, both as regards 

 place and time. These, over forty in number and covering a re- 

 markable variety of subjects, are now garnered and form a handsome 

 volume, which will be welcome to zoologists, especially to those who 

 have had the advantage of their author's friendship. The articles, 

 which are written in an attractive style, include many that have 

 been seldom, if ever, treated upon from Mr. Harting's standpoint, 

 and the information he affords and his critical remarks thereon 

 are extremely useful and acceptable. 



The book is nicely got up and well illustrated, and the frontis- 

 piece is an excellent portrait of the author with one of his favourite 

 falcons on his wrist. 



ENTOMOLOGY, WITH SPECIAL REFERENCE TO ITS BIOLOGICAL 

 AND ECONOMIC ASPECTS. By Justus Watson Folsom, Sc.D. 

 (Harvard). London: Rebman Limited, 1906. Svo. Pp. 485 

 and 5 Plates (one coloured). 143. net. 



The author of this new work on Insects is to be heartily con- 

 gratulated on having produced a most excellent handbook on entirely 

 new lines. The whole treatment of the subject is most lucid and 

 refreshing, masterly and entertaining. We have seldom seen the 

 innumerable facts relating to entomological matters presented in a 

 more attractive form, and the book is eminently readable and 

 suggestive from beginning to end. For an example of the lucidity 

 of style in dealing with a difficult subject we need only refer the 

 reader to the account given on pp. 103-109 of the Sounds of Insects 

 and Hearing. The illustrations, of which there are some 300, are 

 exceedingly well executed and happily chosen, a large number of 

 them being original. Plates I. and II. are novel and of much 

 interest, showing the successive stages in the pupation and emergence 

 of the imago of the well-known Milkweed Butterfly, Anosia plexippus. 

 We notice, by the way, a slip on p. 18, in estimating the number of 

 described species of Coleoptera as 18,000 this figure only re- 

 presenting about one-fifth of the actual number at present known. 



The book is divided into thirteen chapters, commencing with
