whilst 65 are winter visitors and 75 occasional visitors. The range 

 of each is carefully traced through the countj^, and the time of arrival, 

 nidification, number of broods, number of eggs, comparative abun- 

 dance, together with numerous notes of local interest and peculi- 

 arities of habit, are given. 



In short, Mr. Mitchell has performed his task well, and has 

 obviously been at much pains to render his information as complete 

 and reliable as possible. The work will be welcome and useful to 

 all who take an interest in British birds, and must prove indispen- 

 sable to the many north- country artisan-naturalists whose leisure 

 time from toil in noisy mill or factory is spent in studying natural 

 history in the suburbs of their crowded towns. We hope that 

 provincial naturalists will not rest until every county not yet 

 favoured with a handbook to its bird-life can boast of one planned 

 with as much care and carried out with as much completeness as 

 the useful and interesting little volume before us. C. D.

The Memoirs included in Mr. Ljdekker's third volume of Indian 

 Tertiary Yertebrata are varied in matter and vary in importance. 

 We may say of the volume as a whole, that it makes an important, 

 valuable, and welcome contribution to the knowledge of the subjects 

 of which it treats ; and every anatomist will need to examine in 

 detail the materials described and discussed in the successively 

 issued parts of the work. 



Part 1 opens with an account of Aceratherium Blanfordi, founded 

 on materials collected b}^ Mr. W. T. Blanford in the Lower Siwaliks 

 of the extreme west of India. 



Upper molar teeth of two races of this rhinoceros are described, 

 which differ in size. Its affinities are with the Rhinoceros palce- 

 indicits, which, however, has the external surface of the molar teeth 

 flatter. The bases of the two colles are in contact in R. palceindiacs, 

 and that species wants the tubercle at the entrance to the median 

 valley. The distinction of A. Blanfordi from Rhinoceros sivcdensis
