3. Illustrations of African Bloodsucking Flies other than 

 Mosquitoes and Tsetse-flies ; by Eenest Edward Austin. Pp. 

 xv, 221, with 13 colored plates. London, 1909 (British Museum 

 of Natural History). — Since the discovery that many of the most 

 fatal diseases of man and animals are disseminated by means of 

 the bites of blood-sucking flies, the British Museum has published 

 a number of handsomely illustrated monographs on various 

 groups of these insects. Belonging to this series is the present 

 volume, which gives general and non-technical descriptions and 

 excellent colored figures of 103 African species, all of which have 

 blood-sucking habits, although it is not yet known which of them 

 may serve in spreading diseases. . w. e. c. 



4. The Cambridge Natural History ; edited by Haemee and 

 Shipley. Vol. IV. Crustacea and Arachnida. Pp. xviii, 566, 

 with 286 figures. London 1909 (Macmillan & Co.).— The 

 series of ten volumes of excellent treatises by specialists in the 

 different groups of the animal kingdom is now complete, and 

 forms perhaps the most convenient and generally useful work of 

 reference on the subject that has appeared in the English 

 language in recent years. 



The present volume is quite up to the high standard of the 

 others of the series, and treats of the Crustacea, and the widely 

 divergent forms, as king crabs, spiders, scorpions, ticks, mites, 

 water-bears, pycnogonids, and other animals, both fossil and 

 living, which are now generally grouped together as Arachnida. 

 The contributors for this volume are Geoffrey Smith, Henry 

 Woods, A. E. Shipley, Cecil Warburton and D'Arcy W. Thomp- 

 son. The general excellence of the text is shared by the 

 numerous illustrations. w. e. c.
