of the Central Py rentes. 69 



Pau; others, indistinguishable from our form, showing next 

 to no white on the head, 1 met with at Argeles-Vieuzae. 



22. Pakus major, Linn. 



23. Parus ater, Linn. 



24. Parus c.eruleus, Linn. 



Our three common Tits were present in the wooded regions. 

 The Great Tit at Eaux-Bonnes, the Cole Tit at St. Sauveur, 

 and both in the Valle de Ara. The Blue Tit we did not 

 notice across the frontier; we found it nesting at Argel^s 

 and St. Sauveur. 



25. Parus cristatus, Linn. 



Fairly common among the tall pines and spruces of the 

 Valle de Ara and the yew trees above Bucharo. Surely the 

 Crested and Colo Tits are more nearly akin than the other 

 species. They are much given to hunting in company, and 

 in a dusky pine- wood or in thick weather they are not easily 

 distinguished. 



26. SlTTA C^SIA, Wolf. 



One could frequently hear and sometimes see the Nut- 

 hatches among the tall timber around Eaux-Bonnes and in 

 the Valle de Ara. 



27. Certhia familiaris, Linn. 



The Creeper was seen at St. Sauveur and in the hotel 

 garden at St. Bagneres-de-Bigorre. 



28. TiCHODROMA MURARIA (Linu.). 



The only Wall- Creeper we saw was at the upper end of 

 the Valle de Ara, say 6500 feet. It was well described to 

 me by others who knew the district, so 1 suppose it is not- 

 uncommon. 



29. Troglodytes parvulus, Koch. 



One could hear Wrens singing at all hours of the day 

 among the woods at Eaux-Bonnes and in the Valle de Ara. 



30. MOTACILLA ALBA, LiuU. 



I saw the White Wagtail, which is not essentially a
