178 THE ZOOLOGIST. 



Marsh Tit. — W. Somewhat unequal in distribution, but 

 common in many districts ; rare on west coast. I. No authentic 

 record during last fifty years, nor is there any Irish specimen in 

 existence. 



Nuthatch. — W. Very common in Montgomeryshire, but 

 rare elsewhere, and almost unknown on the west coast. I. Un- 

 known. 



White Wagtail. — W. A regular spring migrant, passing up 

 the west coast, but seldom remaining to breed. I. Migrant up the 

 west coast of Ireland ; neither known to visit Wicklow nor Dublin. 

 Yellow Wagtail. — W. Not uncommon as a summer visitant, 

 breeding in the east of Carnarvon and Merioneth, but on the 

 west coast known chiefly as a passing migrant. I. Extremely 

 local ; nest found once near Dublin. 



Tree-Pipit. — W. In spite of repeated assertions to the con- 

 trary, the Tree-Pipit is quite a common bird in all the wooded 

 parts of North Wales, and I have also met with it on open land 

 where there were no" trees, and even seen a dead one near the top 

 of Snowdon. I. No sufficient evidence from any part of Ireland. 

 Pied Flycatcher. — W. Surprisingly numerous in Carnarvon 

 and Merioneth, breeding in all suitable woods. I. Never known 

 to breed ; has occurred seven or eight times at certain light- 

 houses on the autumn migration ; and once in April, in Co. Sligo. 

 Bed-backed Shrike. — W. Generally distributed, though not 

 numerous. I. Only once obtained in Ireland — in Co. Down. 



Hawfinch. — W. Slowly spreading westward, but as yet rare 

 in Merioneth ; unknown on the west coast, in Anglesey, or Car- 

 narvon except near Llandudno. I. Known as a scarce winter 

 visitor, but believed to have nested recently in Co. Dublin. 



Siskin. — W. A winter visitor of uncertain occurrence, but 

 said to have nested once in Carnarvonshire. I. Much com- 

 moner in Ireland ; resident, and breeds in both counties in fair 

 numbers. 



Twite. — W. Appears occasionally in flocks between autumn 

 and spring, but seldom if ever breeds. I. Common resident, 

 breeding in both counties. 



Tree- Sparrow. — W. Occurs in scattered localities in Angle- 

 sey and Carnarvon, but has not been identified in Merioneth. 

 I. Almost unknown except near Dublin, where there is an in- 

 creasing colony established some fifty years ago.
