on the Fauna of the Country of the Chess and Gade," 1 is 

 better worth reading than its title would imply. Two 

 questions present themselves at the outset, the first of 

 which asks the whereabouts of the country dealt with, 

 and the second very naturally enquires what sections of 

 the Animal Kingdom are concerned in the article, which, 

 although 'to be continued', obviously cannot deal with the 

 whole of the fauna of this particular area, however small 

 it be ! Our geographical curiosity is soon satisfied when 

 we read on the first page that the " country " in question 

 is a triangular patch of land about 20 miles in length, 

 lying on the southern side of the Chiltern Hills, in the 

 county of Buckinghamshire. And even before this item 

 of information is gleaned we learn that this first instalment 

 is entirely devoted to Rotifers ! It seems to us a pity 

 that the title of this really interesting paper is not more 

 explicit, for its own sake, since it is liable to be overlooked 

 by just that class of naturalists to whom it would be of 

 value. Many useful notes are given on the habits of 

 these curious little animals, ten species of which are 

 identified and dealt with, while eight figures are given 

 in illustration of various points. 



Students of our native Water-beetles will find Dr Sharp's 

 recent paper, entitled " The British Species of Gyrinus," 2 of 

 great service. The eleven species recognised as belonging to 

 our fauna are carefully described and contrasted, and a useful 

 table provided for the determination of specimens. One 

 species, G. opacus, Sahib., is introduced as new to Britain, on 

 the strength of specimens taken at Invercannich so long ago as 

 1866, and at Braemar in 1871 and 1909. In the same journal 

 (pp. 145-152) the Rev. F. D. Morice publishes a further 

 instalment of his valuable " Help-Notes towards the Deter- 

 mination of British Tenthredinidtz, etc." This is the 32nd 

 paper of the series, and is principally occupied with a 

 synoptic table of the females of the difficult genus Tenthre- 

 dopsis. Two other papers must be alluded to before dismissing 

 the June number of the Ent. Mo. Mag. These are a paper
