the West Tees District, the West Swale District, the Yare 

 District, the Nidd and Wharfe District, the East Tees District, 

 the Esk District, the Derwent District, the East Swale District, 

 the Ouse and Foss District, and the Flora (Flowering- Plants, 

 Ferns, Mosses, and Hepatics). Mr. Slater has also written a 

 lengthy and useful introduction to the Mosses and Hepatics. 

 In the matter of Indices, the volume is likewise well supplied, 

 there being- a Geographical Index, an Index to the Flowering 

 Plants and Ferns, an Index to the Mosses, an Index to the 

 Sphagnums, and an Index to the Hepatics. All these have 

 been carefully compiled, and are an exceedingly valuable addition 

 to the work. It is a pleasure to see a volume of reference, such 

 as this will be for all time, so well indexed. 



The Yorkshire Naturalists' Union is certainly to be con- 

 gratulated on being the means of presenting so useful a work to 

 the scientific world, and it is a matter for reg-ret to learn that 

 this edition is so very limited, and will probably soon be out 

 of print. The volume is very reasonable in price, and anyone 

 interested in the county should not hesitate to buy a copy at 

 once. 



. It is gratifying to find that Mr. J. G. Baker, who published 

 the first edition so long ago as 1863, has been able to see the 

 present work through the press.

 Megachile circumcincta ? Sep. 

 Osmia civrulescens Linn. 



The specimens of this last bee were taken out of a nest made in 

 the wall of an orchard house at Kirton-in-Lindsey. It is a 

 very pretty little bee. The sexes are so remarkably different in
