368 THROUGH THE MACKENZIE BASIN"
specimen many years ago. The number of eggs laid by
tbis species seems to vary from three to seven— the latter
number is rare, however, five and four being the number most
commonly found." Personally he examined some forty nests,
and in no case did he find over five eggs to a set. They are
deposited at intervals of a day. Their shape varies greatly,
the majority ranging from a rounded ovate to an oval, and a
few may be called elliptical ovate. A very peculiarly shaped
set in the U. S, National Museum collection he would call
blunt cuneiform. The ground colour of these eggs ranges
from a pure clear white in a few instances to pale buff or
cream colour in the majority, and to a light cinnamon rufous
in a few others. They are. spotted, blotched, marbled, and
sprinkled with different shades of walnut brown, chestnut,
cinnamon rufous, and ochraceous in various patterns; frequently
these markings are confluent, predominating in some
specimens on either end; in others they are heaviest in the
centre, forming a wreath. Mixed among the various tints
a few eggs show handsome lavender coloured shell markings.
Scarcely any two sets are exactly alike. In some the markings
are regular and minute, in others they are coarse and
bold, and occasionally a specimen is entirely unmarked, being
pure white throughout. He found two such eggs among
first sets. There are but two skins, and no eggs, in the
Ottawa collection!
