Scaup {A. marila). — Is rarely seen ; I have shot only one specimen, 

 a female. 



Long- tailed Duck {A. glacialis). — Is a regular winter visitor toKU- 

 lala Bay ; it arrives in October, and occasionally delays its departure 

 until May. A few stragglers are to be seen in the river, but the greater 

 portion of them remain in the bay, where they are not easily observed, 

 because their feeding grounds are close to the surf of the Killala and 

 Moy bars ; however, when not seen, their very peculiar cry will always 

 call the attention of the observer, and cause him to be on the look out 

 for them. As far as my limited experience goes, I find them to be in 

 this locality the tamest and most easily shot of all the duck tribe. 



Golden-eye Duck {A. dangula). — Is seldom seen on the river before 

 February and March, during which months a few small flocks frequent 

 the river opposite BeUeek, the seat of Colonel Knox Gore, about a mile 

 fromBallina; and they very seldom come farther down the river, unless 

 disturbed. 



Red-breasted Merganser {M. serrator). — Is very numerous during 

 winter in the open bay and river, and a few are to be seen during summer. 

 I have seen them on Lough Conn in May and June, and I have been 

 informed that a few pairs breed on some of its imfrequented islets. 



Eared Grebe (P. auritus). — I have occasionally seen in winter on 

 the river, in February, 1852, I shot a fine specimen, in the winter 

 plumage ; it was in company with another, swimming in the channel 

 near Killala ; I again met with it in the winter of 1855. 



Little Grebe {P. minor) — Is resident in the inland waters ; but I 

 have never seen it on the river here, except when driven down by fr-ost. 



Northern Diver {Colymlus glacialis). — This fine bird is a regular 

 winter visitor, and sometimes, before taking their departure in April and 

 May for their northern haunts, a few assume their beautiful summer 

 plumage. I saw a flock of ten E"orthem Div.ers, of which nine birds ap- 

 peared to be in perfect summer plumage, on the 24th of May, 1851, in 

 the open bay, near KHcummin Head. 



Red-throated Diver (C. septentrionalis). — Is also a regular winter 

 visitor, and, like the Northern Diver, a few birds assume the summer 

 plumage before leaving in April and May. 



Black-throated Diver (C. arcticus). — One in apparently adult plumage, 

 exhibiting the fine black throat, was seen by my brother, Mr. E. H. 

 "Warren, near Bartra, in April, 1851. 



Common Guillemot {U. troile). — Breeds in very large numbers at 

 Downpatrick Head, near Ballycastle, about six miles from Killala. 



Black Guillemot ( U. grylle). — Is common, and breeds round the 

 coast from Kilcummia Head to Downpatrick Head. 



Puffin {F. arctica). — Is only occasionally seen in the bay and river. 

 I shot a young bird of the year, near Rissark Abbey, in the winter of 

 1856. 



Razorbill {A. torda). — Is very numerous, and breeds in the same lo- 

 calities as the Guillemot. After storms, in winter, they are sometimes 

 thrown up dead in numbers on the Bartra shore.
