108 THE ZOOLOGIST. 



Great Northern Diver. — Mr. Coward found the dried remains of 

 one in winter dress in Abersoch Harbour. I have no doubt that 

 Divers are not uncommonly to be seen off this coast. I once saw two 

 Great Northern Divers off Barmouth in May, and at that season the 

 Eed-throated Diver is not at all uncommon there. One morning I 

 saw as many as nine feeding in the shallows. 



I add some notes on Lleyn birds already recorded : — 



Peregrine Falcon. — I ascertained the position of the eyrie of 

 another pair which breed annually in Western Lleyn. Mr. Coward 

 saw last year the birds at a previously-recorded eyrie. 



Merlin. — Seen by Messrs. Coward and Oldham last year in May 

 at Cilan. 



Red-backed Shrike. — On May 23rd, 1901, 1 found a pair, with a nest 

 and two eggs, in a bramble-bush on the cliffs about half a mile west of 

 Aberdaron ; an interesting extension of its known range in this direc- 

 tion ; almost in sight of Ireland, where this Shrike is practically 

 unknown. 



Mistle-Thrush and House-Martin. — We all three agreed that 

 these birds were more common last year than we had previously known 

 them ; the former seems fairly common. 



Grasshopper- Warbler. — We heard in the marsh at Abersoch. 



Goldfinch. — I noticed at Llanbedrogg, and Messrs. Coward and 

 Oldham at Abersoch and Boduan. 



Chough. — Messrs. Coward and Oldham observed it at an inaccessible 

 spot on the north coast. 



Whimbrel. — Evidently not uncommon on the spring migration. I 

 saw two alight on St. Tudwal's Island, and several others passing over 

 the district. 



Purple Sandpiper. — Reported by the lighthouse-keeper as present 

 on St. Tudwal's Island again this May — about the 24th. 



Lesser Tern. — I saw a pair in Hell's Mouth Bay, and another at 

 Abersoch ; and Mr. Oldham reported a score in Pwllheli Harbour on 

 June 2nd. 



Tern (Common or Arctic). — One or two seen in Pwllheli Harbour 

 on May 29th by Messrs. Coward and Oldham. 



Heron. — I am told that there is a heronry near Pwllheli. Herons 

 are generally to be seen in Abersoch Marsh ; on May 26th two rose 

 from the marsh, one of which held in its bill a wriggling eel about a 

 foot and a half long. 



Shag. — More breed on the islands (where they are quite safe) than
