1. A Text- Book in General Zoology ; by Henry R. Linville 

 and Henry A. Kelly. Pp. x + 462, with 233 illustrations. New 

 York, 1906 (Ginn & Company). — This is an elementary text- 

 book designed particularly for secondary schools. It contains, 

 however, a vast amount of matter of interest to the general 

 reader and in this respect differs widely from most books of the 

 kind. The pupil or reader will here find the dry bones of anat- 

 omy and classification clothed with interesting accounts of habits, 

 life history, relationship, and evolution, while the bearing of each 

 fact on the general principles of biology is indicated. The book 

 is to be accompanied by a pamphlet of suggestions for labora- 

 tory work. With a suitable laboratory course and judicious 

 selection of topics the study of this book should arouse in the 

 mind of the young student a love of nature and an eagerness to 

 make the personal acquaintance of the animals considered, 

 although many elementary courses are conducted in such a way 

 as to secure an exactly opposite result. A large part of the 

 illustrations are original and are unusually attractive, w. r. o. 



2. Illustrations of British Blood-sucking Flies with notes ; 

 by Ernest Edward Austen. Pp. 74; 34 plates. London, 1906 

 (Printed by order of the Trustees of the British Museum).— 

 This work consists of reproductions of colored drawings pre- 

 pared for exhibition in the British Museum, with interesting 

 comments in popular language on each of the species illustrated. 

 The 34 plates are well printed by the three-color process and 

 represent the insects many times natural size, with few excep- 

 tions each figure occupying the whole of a large octavo plate. 

 They might, therefore, be used to advantage to accompany the 

 actual specimens in museums other than the one for which their 

 originals were intended. This is particularly the case because 

 many of the species are of very wide distribution, occurring not 

 only in Great Britain, but also throughout Europe, Asia, and 

 North America, and some in Africa and Australia. w. R. c. 



3. A /Synonymic Catalogue of Homoptera. Part I. Cicadi- 

 dce; by W. L. Distant. Pp. 20*7. London, 1906. (Printed by 

 order of the Trustees of the British Museum. Sold by Longmans 

 & Co., etc.) — This first part of the British Museum Catalogue 

 of Homoptera is devoted to Cicadidse, and is prepared by Mr. 

 W. L. Distant, who has given particular attention to this family 

 of the Rhynchota. The fact that there has been no catalogue of 

 the family published recently gives especial value to this exhaust- 

 ive work.
