Sharpe's noraenclatui'e and arrangement. It is based on 

 8474 specimens then in the Museum which are referred to 

 907 species, and is illustrated by 10 coloured plates. The 

 fourth volume, published in 1906, prepared under the same 

 joint authorsliip, continues the account of the eggs of the 

 Passeriform Birds. It is based on the series of 14,917 

 specimens belonging to this section contained in the 

 Mnseuin. These are referred to 630 species, and the volume 

 is illustrated by 14 coloured plates. 



After 1906 a lamentable delay occurred owing mainly 

 to the bad health of Dr. Sharpe, and the pressure of other 

 matters on the under-manned staff of the Bird Department. 

 Those who wish to know the reason why the issue of the 

 fifth and final volume (now before us) was not published 

 long ago should read the Preface and Mr. Ogilvie-Grant's 

 Introduction to the volume. The enormous number of 

 specimens (19,283) is quite sufficient to account for tlie 

 delay, let alone the pressure from other matters, well 

 known to many of our readers. But take the five volumes 

 as a whole, and as a solid contribution to Oology there is 

 nothing like it been even attempted. Errors and mistakes 

 of various kinds may easily be found in it no doubt by 

 those who wish to criticise, but our verdict is decidedly 

 favourable to the ' Catalogue of Birds' Eggs,' which is an 

 excellent and most useful piece of work, especially for 

 Oologists. 



It must always be remembered that the identification of 

 eggs must rest with the collector and that the author of such 

 a work as the present is bound to accept the collector's 

 identification unless he has exceedingly strong reasons for 

 rejecting it, and in this case his only logical course is to 

 destroy or make away with the wrongly identified specimens 

 as being a source of error to future workers.
