THE BIRDS of LLEYN, WEST CARNARVONSHIRE. 

 By O. V. Aplin, F.L.S.

 promontory, and many other lesser ridges, break up the country ; 

 while the coast headlands grow bolder as we go westward, and 

 reach their greatest height in Mynydd Annelog, a little to the 

 north of the land's-end of North Wales, and Graig ddu and 

 Penarfynydd, which run out from the Rhiw hills. The rushing 

 mountain torrent is consequently wanting, and the little rivers, 

 although quick in places, and clear as to their waters, flow often 

 quite sluggishly through reeds and flags and lush green marshes,

 is not found in the western parts of Lleyn ; but, though I looked
