segregation of the two forms. The specimens sent to the 
British Museum by our friend Count von Berlepsch have the 
other character of the true Mi. caudatus , viz., the whiter second, 
aries, and there is nothing, therefore, to show that they are not 
the immature birds of the. northern race, Mi. caudatus. 
In Spain and the greater part of Italy a distinct species of 
Long-tailed Tit, sE. irbii , occurs. How far this form extends 
into France has never yet been determined, but that it occurs 
in that country is shown by a specimen which we ourselves 
shot at Mongeron (Seine-et-Oise), not far from Paris. 
The members of the genus EEgilhalus do not breed in holes, 
but make a moss nest in the open, and in this teature the 
genus sEgithaliscus follows suit.
