28 CHECK LIST OF THE 



GENUS MACRORHAMPHUS. 



(231) Dowitcher. 



(Macrorhamphus griseus.) 



Formerly this bird was not uncommon on the shore of Lake Ontario 

 during the migrations, but now it is a rather rare spring and autumn 

 visitor. 



GENUS MICROPALAMA. 



(*) ( 2 33) Stilt Sandpiper. 



(Micropalama himantopus.) 



A rare visitor. I have never met with this species in its spring mi- 

 gration northward, but have several times taken it, on its return in July 

 and August. 



GENUS TRINGA. 



(234) Knot. 



(Tringa canutus.) 



In the neighbourhood of Toronto and Hamilton I have found this 

 species abundant from the twenty-fifth of May to the end of the first 

 week in June. In the autumn it is seldom seen. Two or three times I 

 have taken specimens in immature plumage in August, but that is all. 

 Breeds in the Arctic regions. 



GENUS ARQUATELLA. 



(235) Purple Sandpiper. 



(Arquatella maritima.) 



A very rare visitor from the northern sea coast, usually occurring 

 late in autumn. Breeds on the shores of the Arctic Ocean. 



GENUS ACTODROMAS. 



(239) Pectoral Sandpiper. 



(Actodromas maculata.) 



A common visitor to our marshes and sandbars. Not observed by 

 me in the spring. 



Arrives in July and departs about the end of October. 



(240) White=rumped Sandpiper. 



(Actodromas fuscicollis.) 



Rather an uncommon species. Possibly breeding, as I have found 

 them here, from the middle of June to the middle of October.
