time of year. On some specimens the white nape-patch 

 shows a slight yellowish tinge, which may be a sign of a 

 freshly moulted young bird. 



The olive-brown colour of the back is always very 

 pronounced from August and September to January ; it 

 becomes a little less obvious as the breeding-season 

 approaches, and the colour of the back becomes slightly 

 more grey as the plumage becomes worn, but it is never 

 so blue as in the continental bird. 



Parus vieirae, n.sp. (PI.) 



There is in the British Museum a specimen, from 

 Portugal, which appears to belong to an undescribed form 

 of Coal-Tit, and for which I propose the name of Parus 

 vieirae. 



Similis P. britannico, sed regione uropygiali et corpore 

 subtus pallide cinnamomeisdistinguendus. Long. tot. 4"0, 

 culm. 04, alae 2-2, cauda i'6, tarsi 07. 



Hab. Coimbra, Portugal (Dr. L. Vieira). 



The dull cinnamon-rufous colour of the underparts 

 which gives a rufous appearance to the bird is quite 

 different from the fulvescent tint found in P. ater and 

 P. brita7iniais. Dr. Sharpe tells me that he has shown 

 the type to Dr. Bianchi and Dr. Hartert, and that they 

 both confirm my idea of its distinctness. 



Parus sardus.

 This is said by Pastor Kleinschmidt to be easily 

 recognisable from true P. ater by its bright rust- coloured 

 sides. The English form, he adds, is not so bright in 

 colour on the flanks, and has likewise a duller colouring
