descending process of the lacrymal Ceryle is intermediate between 

 the two other genera. 



In internal characters therefore, at least in the skeleton and 

 the deep plantar tendons, Ceryle bears a much closer resemblance 

 to Chloroeeryle than to Megaceryle, agreeing better with the latter 

 only in the somewhat broader maxillary. While this conclusion 

 is probably correct it cannot be considered final until confirmed 

 by examination of the remaining species, particularly Megaceryle 

 guttulata or M. lugubris.

The following notes refer chiefly to the birds of Toronto, On-

Since the senior author published his article " Birds of Toronto, 

 Ontario," 1 twelve years ago, there has been much change in con- 

 ditions affecting bird-life near Toronto. The land birds have 

 not been seriously affected. The ravines, especially those of the 

 Don and Humber Rivers, form decided obstacles to the expansion 

 of the city and still contain wooded tracts which provide shelter 

 and food for many migrants. However, the Humber River is 

 now flanked by an automobile road and since the completion 

 of the Bloor Street Viaduct the ravines of the Don Valley, already

 city. 



There has been a large aerial training camp on the banks of 

 the Don, from which aeroplanes have been flying in scores for 

 the past three years, but they did not drive away the smaller 

 birds. Large hawks and gulls have been seen, pursued by the 

 cadets in their aeroplanes, and fleeing in terror before such huge
