taken May 19, 1872. Unlike the other species of this genus, which, so 

 far as is known, build their nests on the ground, this little warbler was 

 found nesting in the manner of the common Grey Creeper, under 

 the loose bark of- the trunk of a dead tree, a few feet from the ground. 

 The eggs also bear a great resemblance to those of the Creeper, but 

 are of course smaller. In shape they are nearly spherical, their 

 ground is of a crystal whiteness, spotted, chiefly around the larger 

 end, with fine dotting of a purplish red, and measuring .51 of an 

 inch in length by .45 in breadth. 



Pyranga hepatica. Rocky Mountain Tanager. 



Two eggs of this species measure 1.02 inches in length by .67 of 

 an inch in breadth; the other .95 by .70 of an inch. Their ground 

 color is a pale light green. One is somewhat sparingly marked over 

 the entire egg with very distinct and conspicuous blotches of purplish 

 brown. The other egg is much more generally covered with finer 

 dottings of the same hue, and so numerous as partially to obscure 

 the ground. The eggs are of an oblong oval shape, rounded and 

 nearly equal at either end. 



Harporhynehus erissalis. Red-vented Thrush. 



The eggs of this species were first discovered by Dr. Palmer, in 

 Arizona. They have been since met with by Capt. Bendire, and 

 confirm the anomaly of their markings. They are unlike the eggs 

 of any other known member of this genus, and are of a light robin- 

 blue color, unspotted, and hardly distinguishable from the egg of our 

 common robin, Turd us migratorius. They are of an oblong oval 

 shape, rounded, and nearly equal at either end, and measure 1.10 

 inches in length by .75 of an inch in breadth. 



Harporhynehus curvirostris. Variety Pahneri. 



Two sets of eggs taken, one July 18th, the other Aug. 2d. Both nests 

 were built in cactus plants, a few feet from the ground. The eggs in 

 each instance were three in number. Their ground color is a light 

 blue, generally and profusely sprinkled with fine dottings of a light 

 golden brown. They are of an oblong shape, tapering at one end, and 

 rounded at the other, and measure 1.10 inches in length by .82 of an 

 inch in breadth. A nest of this species was also found in Arizona 

 by Dr. Palmer, corresponding in all respects with those found by Capt. 

 Bendire. 



Harporhynehus bendiri. 



The nesi from which these eggs were taken was found July 19th, 

 1872. It was built in a mesquite bush, or low tree, and was five feet
