55G ?sE8TS AND IHXJS oK AlilZONA BIRD.'-'. 



Museum collection, coutaiiiiug ueaiiy three hundred specimens, almost 

 all obtained from Lieutenant Benson. Their groundcolor ranges from a 

 light green to a pale grayish green, and this is more or less covered with 

 numerous streaks, blotches, and spots of sepia-brown and French-gray, 

 as well as in some instances of dark moss-green and deep grayish olive 

 markings. One peculiar and constant feature of these eggs is, their re- 

 semblance in the i)attern of the less pronounced markings (the lighter 

 colored ones) to those found in the eggs of the genus Myiarchus, in this, 

 that these markings run lengthways with the egg, or from pole to pole, 

 a feature not found by me in the eggs of the common ('row, Corviis 

 americanus AUD., and only very rarely in those of the Haven, Gorrus 

 corax sinuafus Wagl., the eggs of both of these species being also re})- 

 resented by excellent series in the Museum collection. The general 

 average of the eggs of the White-necked Eaven is much lighter colored 

 than the eggs of the above-mentioned species ; one set, indeed, is almost 

 unspotted, and usually there is one egg in each set which is much lighter 

 colored generally, than the balance. All the eggs of this species can 

 readily be distinguished from those of the balance of the Corvidw whi(;!i 

 breed within the limits of the United States. The usual shape of these 

 eggs is an elongated ovate, and there is a great variation in their size. 



Three of the largest measure as follows : 1.92 by 1.33, 1.9G by 1.25, 

 and 2 by 1.24 inches. 



Three of the smallest measure 1.57 by 1.17, 1.G2 by 1.08, and 1.52 by 

 1.00 inches. Their average size is about 1.78 inches in length by 1.10 

 in width. 



From four to seven eggs are laid to a set, six being the most common 

 number found, and presumably but one brood is raised a year. 



NO. 632a. VIREO HUTTONI STEPHENSI Bkewster. 

 Stephens' Vireo. 



This new race was first described by Mr. William Brewster, in the 

 Bulletin of the Nuttall Ornithological Club, Vol. VII, July, 1882, paijes 

 142 and 143, from specimens collected by Mr. F. Stephens in the Chiri- 

 ciihua and Santa Rita Mountains, Arizona. It is stated that he also 

 took the nest and eggs of this race near Fort Bayard, N. Mex., in 

 1S7G, but I am unable to find any description of the sauie in any of the 

 ornithological publications to which I have access. 



A nest of this bird containing three fresh eggs was taken by Lieu- 

 tenant Benson on June 21, 1887, near Fort Huachuca, Ariz., and is 

 now in the National Museum collection. The nest was attached to the 

 fork of a small twig of some species of buttonwood, probably Flata- 

 nus wrighfii, growing in a canon of the Iluachuca Mountains. The nest 

 was not well concealed. The birds are common in such localities and 

 very tame. It is very peculiar looking, being outwardly exclusively 

 composed of what I take to be a fine yellowish buff plant-down, with
