Recently published Ornithological Works. 449 



The January number of the ' Scottish Naturalist ' for this 

 year commenced a new series^ under the Editorship of Mr. 

 W. Eagle Clarke, of the B.O.U. Amongst the ornithological 

 papers is a list of the birds observed in the valley of the Spey, 

 prepared by Mr. William Evans, also of our Union. Mr. 

 Evans enumerates 90 species as observed duriug his holiday 

 in this district in 1889, when his abode was at Kincraig, 

 near Loch Insch. Parus cristatus was often seen in the 

 pine- woods, and is " by no means rare ; " they were always 

 in company with Cole-Tits and Gold-crests.

The present part of the 'Biologia' (see above, p. 276)' 

 carries on the account of the Central- American Cotingidse 

 nearly to its termination. As regards the typical genus 

 Cotinga some new advances are made. It is pointed out 

 that the remarkable diflFerences in the comparative lengths 

 and forms of the primaries in the adult males are sufficient 

 to distinguish the eight known species, or most of them;
