Report on Amendments and Alterations [Ibis, 
XVII.— Report ' of the Sub-committee , consisting of Dr. E. 
Hartert, Messrs. T. Iredale and W. L, Sclater, on 
Amendments and proposed Alterations to the Names in the 
B. 0. U. List of British Birds , as accepted by the Committee 
of the B. 0. U. on the British Birds List. 
The following recommendations were made :— 
1. That the nomina conservanda in the B. 0. U. List should 
not be .used any longer, but the correct mimes under 
the rules should now be universally adopted. 
There are thirteen of these nomina conservanda , and 
a list of them with their equivalent under the Rules 
of Nomenclature is given on p. 355 of the B. 0. U. 
List, in Appendix II. 
2. That in future, when a species has been divided into two 
or more subspecies, the typical subspecies should 
always be named trinominally. For example, the 
. typical race of the Starling should be called Sturnus 
vulgaris vulgaris and not Sturnus vulgaris , as the use 
of the binomial form of the name causes confusion 
between the typical subspecies and the species as a 
whole, including all the races. 
3. That the names in Yroeg's Catalogue be accepted. The 
following changes will result: 
p. 69. For Sylvia subalpina substitute 
Sylvia cantillans ( Motacilla cantillans [Pallas] in 
Yroeg’s Cat. Verzam. Yogelen Adumbraticula, 
p. 4, 1764 : Italy.) 
p. 108. For Muscicapa grisola substitute 
Muscicapa striata (. Motacilla striata [Pallas], t. c. 
p. 3, 1764 : Holland).
