TITMICE 63 



from the true Pari has been long since admitted 

 by naturalists ; and, as Dr. Giinther has pointed 

 out {Ibis, 1865, p. 97), the employment of the 

 generic term Acredula of Koch to designate the 

 former group is strictly in accordance with the 

 rules of zoological nomenclature laid down by the 

 British Association. Dr. Sharpe has suggested {Ibis, 

 1868, p. 295) that, as the Long-tailed Titmouse 

 of Scandinavia (described by Linnaeus as Panis 

 caudatus) differs from the British species in having 

 a white head, the latter should be distinguished as 

 rosea of Blyth, that name being the next in order 

 of precedence. The white-headed form, however, 

 occasionally occurs in this country. I have seen two 

 specimens, as recorded in my "Birds of Middlesex," 

 p. 59, which were taken in the north of England ; 

 it has been found in Cumberland (Macpherson, 

 "Fauna of Lakeland," p. 105), and the late Mr. 

 Gatcombe saw one in Somersetshire {Zool., 1872, 

 p. 2943). Moreover, the British form, A. rosea, 

 occurs in France, the Netherlands, and Western 

 Germany. A noticeable feature in both is the 

 colour of the orbits, which is bright orange, as in 

 the Dartford Warbler.
