The young, in their first plumage, have no trace of the

* A specimen of the well-known North -American Ruby-crowned Wren (Mota- 

 cilla calendula, Linnaeus), shot by Dr. Dewar in Kenmore wood on the banks of 

 Loch Lomond in the summer of 1852, was exhibited by Mr. Robert Gray at a 

 meeting of the Natural History of Glasgow, April 27th, 1858, and, May llth of 

 the same year, by Mr. Gould at a meeting of the Zoological Society of London 

 (Proc. Zool. Soc. 1858, p. 290). This species, which ranges over the greater part 

 of the North -American continent, has also, according to Prof. Reinhardt (Ibis, 

 1861, p. 5), wandered to Greenland, and therefore the possibility of its occur- 

 rence in Britain is rendered less strange. It differs from others of the genus 

 Regulus, to which it is commonly assigned, by not having each nostril protected 

 by the peculiar single feather already mentioned as one of the characteristics of 

 those birds, and consequently Dr. Cabanis has proposed to separate it from Regulus 

 under the generic name of Corthylio (Journ. fur Orn. 1853, p. 83). A second 

 specimen is mentioned by Dr. Bree (B. Eur. ii. p. 114) as having been obtained 

 in Durham, but this proves to belong to the species next to be described, and, as 

 Mr. Hancock kindly informs the Editor, its capture in that county cannot be fully 

 established.
