and the sun coming out the wintry effect was speedily dispelled. 

 The other days were cloudless. 



The collection of birds made during my stay embraces a hun- 

 dred and fifty-one skins, the catalogue numbers of the same run- 

 ning from Nos. 2174 to 2324, inclusive ; this I mention, as it will 

 be necessary to refer to certain birds obtained.* Birds on the 

 whole were much more abundant than during the former visit, but 

 certain species that were met with in November, 1SS4, I did not 

 detect during the present trip ; and the more noticeable among 

 these are Carpodacus cassini, Hesperiphona vespcrtiua, and 

 Sphyropicics thyroideus. Others, then comparatively common, 

 were now apparently rare, as I only saw one Olive-headed War- 

 bler {Peiicedramu s olivaceus) . The species obtained are the 

 following : 



Turdus unalascae auduboni. — On April 22, on the very 

 summit of the mountains, I observed a pair of Thrushes, appar- 

 ently mated, and took the female (No. 2234), which, on dissec- 

 tion, proved to be about to lay, the egg-yolks being some of them 

 nearly half developed. This was the only pair of Thrushes ob- 

 served, f 



Sialia mexicana. — A few pairs were noticed at a high altitude 

 in the pine region ; and being already apparently mated, they 

 doubtless breed early in May. 



Polioptila caerulea. — A pair, taken on April 20, about fifteen 

 hundred feet below the summit, where the pines almost cease, 

 and where the evergreen and scrub oak are the principal trees. 

 Here this species was common. 



Lophophanes wollweberi. — Not uncommon in the oak 

 belt, just reaching to the lower pine limit. It is in places abun- 

 dant in the oak region, and in this range of mountains the first 

 set of eggs is laid by the 20th of April. 



Sitta carolinensis aculeata. — Rather common, but by no 

 means so abundant as in the winter. A female (No. 2265), 

 taken April 22, had laid a full complement of eggs and had evi- 

 dently begun sitting.

 Scott, with the request that I should add such remarks respecting them as seemed 

 called for.— J. A. ALLEN.]

 'bleached out' specimen I have seen. — J. A. A.]
