close sitter. When the eggs are " liard-sct " sucli is doubtless 

 the case, but a series of observations made during some 

 twenty years shew that, even when there is a full clutch of 

 fresh eggs, it is seldom possible to approach quietly enough 

 to find the bird on her nest. She usually leaves it ^' at long 

 range/^ 



Again, the Grasshopper-Warbler is even now plentiful in 

 many years in the Cambridgeshire Feus, and builds there on 

 the ground among the sedges, more commo! ly than in the 

 grass. A single specimen of the Kecd- Warbler has now 

 been taken at an Irish lighthouse, and Evans has found a 

 Marsh- Warbler's nest in a tuft of Willow Herb at Horsey in 

 Norfolk.

We are all acquainted, more or less, with the excellent work 

 Baron Loudon is doing on the Birds of the three Baltic 

 provinces of Russia. We have now received a copy of what 

 appears to be a kind of summary of his work and a revised 

 list of the species as yet recognised as occurring in this 

 interesting district. 



After a preface, which deals with previous authorities on 

 the subject, follows the list of the birds of the three 

 Provinces in a tabular form, which contains the names of 

 300 species. It also states in which of the three Provinces 

 the species occurs, and whether it is a resident or a more or 

 less scarce visitor. Altogether we find enumerated : —

We think that students of the Paliearctic Avifauna will 

 find this a verv useful and instructive list.
