rump and flanks are less olivaceous and more rusty -buff, and 

 sometimes the whole under-parts are buflF as in the type- 

 specimen, which was at one time thought to bo an aberration. 

 The cheeks are usually tinoed with yellowish-buff. In the 

 juvenile the sooty-black of the throat extends, as it does in 

 P. a. ater, farther on to the breast than in P. a. hritannicus^ 

 but the under-parts are very different from either in tone 

 of coloration, being considerably buff and not so yellow. 

 The wings of a series of adults (9 males, 4 females) from 

 Portugal measure: males 57-59, females 53-56 mm. Tbose 

 from Riano (4 males, 3 females) measure : males 58-60, 

 females 59 and one 62. The last is larger than any 

 Portuguese Coal-Tit I have seen, but in colour it is typical 

 vieircc. 



Par us cristatus mitratus Brehm. 



Crested Tits, which we found common at Riaiio, were 

 much scarcer on the lower ground about Potes and Panes. 

 They were all of the central European form. In Portugal 

 and as far south as Algeciras P. c. iceigoldi is found, and 

 one bird which I got at Vigo is of this form, as is one from 

 Arosa Bay collected by Surgeon-Admiral Stenhouse, though 

 this is not very typical. I have recently given the distinc- 

 tions of P. c. weic/oldi (Ibis, 1921, p. 581), and I may add 

 that the colour of the upper-parts varies somewhat and in 

 some examples is considerably tinged with rust-colour. 



Parus palustris communis Baldenstein. 



Although Irby meiitious the Marsh-Tit as occurring in 

 this district I was surprised to rind it comparatively common 

 in the more open parts of the woods near Riauo and Potes, 

 while at Panes it was scarcer. Marsh-Tits from the 

 Peninsula are not represented in any of the collections I 

 have examined, and of recent years its presence in Spain has 

 been regarded as somewhat mythical, notwithstanding Irby's 

 record and Saunders's statement (ibis, 1871, p. 208) that the 

 bird occurred near Granada and Cordova in spring. In 1919 

 I obtained one on the Spanish side of the Pyrenees, but this
