nminiiig diiriiii,' the winter; most of these had white C(lginji:s on nil their feathers, 

 and were probably jonng of the year. Their fliglit is described as wavering, some- 

 thing liite that of Coluptes viexicanits. AViiile flying tliey utter a high note, resembl- 

 ing u'liiiif-wliHif, repeated scverid times. Ho never heard them sing, as they are said 

 to do, altiiougli he has watched them frecpiently. They arc very restless, and are 

 always fomid alioiit the mistletoe, on the berries of which they feed almost extlu- 

 sively. The nest is saddled on a horizontal branch, generally of a mes(piite-tree. 

 It is a shallow stnictiii'c, about 4 inches across; its inner diameter is '1\ inches, 

 <le|ith \ an inch. It is coni[Kiscd of fine; sticks, fibres of plants, and lined with a 

 little Cottonwood down and a stray feather. The (irst nest was fonnd May 10. 

 Tiiis was ])rincipally lined witli tiie shells of emi)ty cocoons. The mnnber of eggs 

 was two. Thongh he foinid moro than a dozen nests with eggs and young, he 

 never fonnd more than two in a nest. Their ground-color varies from a greenish- 

 white to a lavender and a grayish-white, spotted all over with different shades of 

 brown. Tiie s])i)ts are all small, and most al)nndant about the larger end, and vary 

 greatly in their distriiiutions. In size they range from .97 of au inch to .84 in 

 length, and in breadth from .(515 to .00.

Fjnranga hepatica (I, 440). Captain Bendire found what he identified as 

 this species breeding near Tucson, Arizona. Its nests and eggs resembled those of 

 P. (I'stlva. The latter vary in length from 1.02 inches to .95, and in breadth 

 from .70 to .07 of an inch. Their ground-color is a pale light green. Some are 

 sparingly marked over the entire egg with very distinctive and conspicuous blotches 

 of purplish-brown ; others are covered more generally with finer dottings of the 

 same hue, and these are so numerous as partly to obscure the ground. In shape 

 the eggs are ol)long oval, and arc of nearly e(iiuil size at either end. This species 

 was also obtained by Mr. Ilenshaw, at Apache, Arizona. 



As no skins of the parent appear to have been preserved, it is not improbable 

 that the bird in question may be really P. a-ativti, var. cooperi. 



Hesperiphona vespertina, var. montana (I, 450). Two ad(dt males 



obtained at Waukegan, Illinois, in Jamiary, 1873, by Mr. Charles Douglass, are 

 typical examples of the Rocky Mountain form. 



Pinicola enucleator (I, 453). Dr. Cooper mentions having shot a fine male 

 of this species near the smnmit of the Central Railroad Pass at an elevation of 

 about 7,000 feet. It was in a fine orange-red plumage. It was moulting, and 

 appeared to be a straggler. 



P3ITrhula cassini (I, 457). Since the publication of the article on this spe- 

 cies we learn from Cabanis (Journal fur Ornithologie, 1871, 318, 1872, 315) that 

 the species is not \mcommon in the vicinity of Lake Baikal, in Siberia, and that it
