116 BRITTAIN AND Cox, Pestigouche Valley Birds. [April 
completely. The largest egg of the series, comprising 115 speci- 
mens, measures .96 X .68 inch, the smallest .74 x .60 inch. 
This egg, however, is abnormally small, the remaining ones in 
the same set coming fully up to the average size, which is .88 x 
-63 inch. The shape of the eggs of the genus Passere//a is ovate, 
with very little variation in this respect. Comparing the eggs of 
this genus with those of Zonotrichia and Melospiza, to which 
they are most closely allied, it will be found on a critical compari- 
son that, aside from their uniformly larger size as a whole, there 
is also more difference in the coloration and markings than would 
appear to the superficial observer; in a word, the general pattern 
varies to a considerable extent, and while occasionally sets of 
eggs of these different genera may resemble each other rather 
closely, the greater number show very distinct characteristics of 
their own, which are easily enough noted by the odlogist, but not 
so readily described. 
NOTES ON THE SUMMER BIRDS OF THE RESTI- 
GOUCHE VALLEY, NEW BRUNSWICK. 
BY JOHN BRITTAIN AND PHILIP COX, JR. 
THE REsTIGOUCHE RIvER flows easterly through the extreme 
northern part of New Brunswick, and before emptying into the 
Baie des Chaleurs, forms for sixty miles the boundary between 
New Brunswick and Quebec. The greater part of the valley is in 
about latitude 48° N. The country is undulating, in some places 
mountainous, and almost an unbroken forest. Winter is very 
severe ; snow falls to a great depth and lingers until May; while 
chilly east winds, from the icy Gulf, make spring late and cold. 
Summer, however, is warm, except near the sea, where it is 
tempered by cool breezes ; yet the nights, even in July, and far up 
the valley, are occasionally frosty and cold enough to form ice. 
About 110 miles of the valley, namely from the mouth of a tribu- 
tary called the Wagan, to Campbellton, situated at the head of 
the estuary, were pretty thoroughly investigated, and although the
