place, taken in 1846 (vide ' Ootheca Wolleyana, part ii. p. 472). 

 There is no mountain of this name at Aberdaron, and it does not 

 look like a Welsh name. Probably Mynydd Annelog was in- 

 tended. I doubt if there are more than a couple of pairs of 

 Choughs now remaining all along this piece of the mainland 

 coast. What becomes of the young birds, which are undoubtedly 

 reared, is somewhat of a mystery. 



A pair of magnificent Great Black-backed Gulls looked ex- 

 ceedingly well on a green-topped stack at the foot of the great 

 cliffs looking out towards Bardsey, but there were no eggs on the 

 stack. In one or two places among these barren storm-swept 

 mountains a little deep cwm runs in from the sea, with a 

 trickling stream at the bottom. These green cwms are so rich 

 and lush that the contrast is striking. Deep in the good grass 

 which makes Lleyn's early lambs famous, they stand in spring so 

 thick in places with primroses in full bloom that one literally 

 cannot walk without treading on them. The bracken-fronds are 

 then just uncurling, and exceptionally tall spikes of the early orchis 

 make beds of deep purple to delight a gardener's eye. From the 

 top of Mynydd Annelog most of Western Lleyn is spread out 

 before you. Northward lies a huge chessboard of banked fields, 

 brightened up by golden gorse and white-walled grey-roofed farms, 

 with perhaps a few low trees to shelter them. Small as these 

 clumps are, they are sometimes sufficient for the Green Wood- 

 pecker (which I have seen close to Aberdaron), the Tree-Pipit, and 

 Willow- Wrens. Where the plantations are more extensive, as 

 about the beautiful old house Bodwrdda, with its adjacent stream 

 and tiny valley, there are numbers of Wood-Pigeons and Mistle- 

 Thrushes, Song- Thrushes (not common in the district), Chiff- 

 chaffs, Greenfinches, Spotted Flycatchers, Sedge- Warblers, &c. 

 The Goldfinch, too, breeds. About the banked fields the Corn- 

 Bunting skirls, and the Yellow Bunting is a very common bird. 

 At the back of Mynydd Careg there is quite a little wood, har- 

 bouring the most westerly rookery ; the Rooks, however, are very 

 little seen at Aberdaron. The next rookery I know, going east, 

 is at Sarn. In the middle distance is the dark brown mound of 

 Mynydd Ystum (400 ft.), with Castell Odo, and beyond it the 

 high moorland of Rhos-hirwaen. To the right is the wall of 

 barren-topped hills stretching inland from Rhiw at the corner of
