THE BIOLOGICAL REVIEW. 95 



a rocky nature, grown up with scrub tamarac, spruce and 

 hemlock, and in the lower localities are numerous large swamps. 



There is no large timber in this region. 



One can hardly be expected to give a complete account of 

 the birds of any region in one short season's observations, nor is 

 it my intention to try to do so. I merely give a list of the 

 species observed during the summer of 1892. 



Colymbus lwlbcellii (Holbcells Grebe). — One young bird seen 

 in August, which might indicate its breeding in the vicinity. 



Colymbus auritus (Horned Grebe). — Two young specimens 

 collected ; several others observed. Breeds. 



Urinator imber (Loon). — Said to be extremely common in 

 the spring, breeding in the smaller lakes. Very few seen in the 

 fall. Two were secured by some fishermen near Thunder 

 near Thunder Cape, one in young and one adult plumage. 



Urinator articus (Black-throated Loon). — One specimen of 

 this species was secured from W. H. Davis' dock about the 

 middle of October, but I could not find out whether others had 

 been observed or taken at any time, most people not knowing 

 the difference between it and the Northern Diver. 

 The specimen mentioned was in young plumage. 



Urinator lumme (Red-throated Loon). — In making enquiries 

 about the Black-throated Diver, I was informed by several 

 parties that the Red-throated Loon was often taken in the spring, 

 but seldom in the fall. I did not hear of any being taken this 

 fall. 



Gavia alba. — The gulls are exceedingly plentiful all about 

 Port Arthur, and no doubt the Ivory Gull will hold its own 

 among them. While working in town, two beautiful specimens 

 were brought to me to be mounted. They were secured in the 

 bay, near the breakwater. The fishermen tell me that they are 

 sometimes numerous about the nets, but are always shy. 



Rissa tridactyla. — One specimen of the Kittawake was 

 taken early in November. 



Larus glaucus, laurus marinus. — The Glaucous and Great 

 Black-backed Gulls were sometimes observed among the large 

 numbers of gulls which congregate about the docks, and one
