WARBLERS. 19 



After examining a large series of these birds, I have 

 come to the conclusion that, as regards the wings, the 

 following formulae may be relied on : Wood Wren, 

 2nd primary *= 4th ; 3rd and 4th with outer webs 

 sloped off towards the extremity. Willow Wren, 

 2nd=6th ; 3rd, 4th, and 5th sloped off. Chiff Chaff, 

 2nd=7th ; 3rd, 4th, 5th, and 6th sloped off. 



GOLDEN-CEESTED WEEN. Eegulus cristatus, Koch. 



Resident; migrating eastwards and southwards in 

 autumn, occasionally in large flocks. See Selby's 

 6 Illustrations of British Ornithology,' i. p. 230 ; ' The 

 Zoologist,' 1848, p. 2020; and Stevenson's 'Birds of 

 Norfolk,' i. p. 136. 



FIEE-CEESTED WEEN. Eegulus ignicapillus, Jenyns. 



Occasional winter visitant. Professor Newton in- 

 forms me that the nest found at Blonorton by Mr. 

 Brown, particulars of which were communicated to 

 Mr. Hewitson for his c Eggs of British Birds,' proved 

 to belong to the Golden-crested Wren. 



Fam. TROGLODYTID.E. 

 COMMON WEEN. Troglodytes parvulus, Koch. 

 Resident and everywhere common. 



* The first primary is quite rudimentary, and is therefore not 

 taken into consideration.
