so dark as to be nearly brownish, and in others the surface is almost 

 milk-white. They are often stained in wet weather by the leaves upon 

 which they lie, and are sometimes faintly blotched or speckled with 

 shades of brown. 



Mr. L. Jones, of Grinnell, Iowa, writes that the eggs in that 

 vicinity are deposited about May first. 



Ten eggs measure 1.64x1.10, 1.51x1.13, 1.54x1.13, 1.54x1.14, 

 1.51 x 1. 12, 1.56 x 1.13, 1.53 x 1.13, 1.55 x 1.14, 1.53 x 1. 12, 1.57 x 1.14. 



30(k. Bonasa umbsllus togata (LINN.) 



Canadian Huffed Grouse. 

 Hab. Eastern Oregon and Washington Territory, east to Moose Factory, Nova Scotia, Maine, etc. 



Eggs supposed to belong to this darker colored variety of Ruffed 

 Grouse in my collection from Northern Maine do not differ from those 

 of B, wnbellus. 



300/>. Bonasa umbellus umbelloides (DOUGL.) [473^.] 



Gray Ruffed Growse. 



Hab. Rocky Mountain Region north to Alaska, east to Manitoba. 



The upper parts of this bird are mostly or entirely grayish, and 

 the tail is always of a gray color. It is found in the wooded districts 

 of the Rocky Mountain region of the United States, and as far north 

 as the Yukon Valley in Alaska, in British America, east to Manitoba. 



Captain Goss has a set of five eggs of this bird taken at Kstes Park, 

 Colorado, May 28, 1884. They are creamy buff; some of the speci- 

 mens are almost or quite immaculate, others are faintly and sparingly 

 spotted with lilac brown. The eggs in this set are smaller in size and 

 less spotted than the usual spotted examples of B, umbellns, and unless 

 closely examined the markings would scarcely be noticed. These 

 eggs were taken from a nest on the ground ; the sizes are as follows : 

 1.47x1.11, 1.45x1.12, 1.44x1.12, 1.42x1.15. 



30(k. Bonasa umbellus sabini (DOUGL.) [473^.] 



Oregon KuTed Grouse. 



Hab Northwest coast, from Northern California to British Columbia. 



This sub-species resembles B. umbellus, but the upper parts are 

 darker rusty-brown ; the tail is also usually deep rusty color, rarely 

 grayish. It is known as the Red Ruffed Grouse. 



Mr. Norris has a set of eggs of this bird which are spotted. Six 

 eggs collected in Coos county, Oregon, April 28, 1880, are in my col- 

 lection. Their color is a rich creamy-white, unspotted. The nest w r as 

 a hollow of the ground, made by the bird, and lined with leaves ; it 

 was situated partly under a fallen tree, and quite hidden by a growth 

 of bushes. The inside diameter of the nest was about six inches, and
