90 THE NESTS AND EGGS OF 



common British form in any important respect. The bird 

 is a dweller on the banks of the Scandinavian and North 

 Russian streams, making its globular nest in crevices 

 of the rocks, amongst the exposed roots of trees, and 

 other suitable localities. The nest, so far as I am aware, 

 is not kno\vn to differ from that of its southern ally, 

 due allowance being made for locality and materials 

 obtainable. 



Range of egg colouration and measurement : 

 The eggs of the Black-bellied Dipper are not known 

 to differ in number, colour, or size from those of the 

 Common Dipper. 



Diagnostic characters : The eggs of the present 

 form cannot be distinguished from those of the Common 

 Dipper. The locality of the specimens should amply 

 determine the species.
