of the number and beauty of the illustrations anrl of the prodigious 

 amount of most useful and readable information that has been 

 crowded into the text. 



The volume contains terse descriptions of the Protozoa, Porifera, 

 Ilydrozoa, and Anthozoa. Brief though the accounts of these 

 groups are, yet space has been found to enumerate the systematic 

 position of each, the anatomical structure and life-history, and their 

 economic importance where such occurs. 



The authors. Prof. Jeffrey Bell and Mr. Kirkpatrick, are to be 

 heartily congratulated on basing accomplished a most difficult task 

 in a really admirable manner. Thej' have produced a book that 

 should meet with a warm appreciation from those for whom it has 

 been specially prepared. 



Only ail institution like the British Museum could afford to issue 

 such a volume for the sum of om sliilUnrj ! 



Catalogue of Birds' Et/gs. Vol. II, By Eugexe W. Gates. 

 Pp. 400 ; pis. XV. 1902. 



"We must congratulate Mr. Gates on the completion of the second 

 volume of this really valuable work, which commences with the 

 Charadriiformes and concludes with the Strigiformes. 



In an aU-too-brief Introduction Mr. Gates tells us that the eggs 

 of 726 species have been described, representing some 1500 speci- 

 mens. The description of these eggs is published without any 

 comment whatsoever: and though this, perhaps, in a Catalogue is 

 all that is required, we cannot refrain from expressing a wish that 

 Mr. Gates had given us, from his stores of knowledge, some account 

 of the extent, trend, and probable significance of the variations 

 presented by the eggs of the birds dealt with in this volume. 

 "With Prof. Poulton we " look forward to the time when any 

 description of colour and marking will be considered incomplete 

 unless supplemented by an account of their meaning and importance 

 ill the life of the species." 



This volume is illustrated by fifteen beautifully coloured plates 

 drawn by Mr. Grunvold.
