Some Summer Birds of the Pocono Mountains, Pennsylvania. — During 

 the past summer I spent a few days— July 2-4, 1S93 — collecting in the 

 immediate vicinity of Mt. Pocono, Monroe Co., Pennsylvania, and 

 observed the following 'northern' species, all of which were undoubtedly 

 breeding at that locality. The notes which accompany each species 

 are based either upon my own experience or upon that of my friend, 

 Mr. William A. Shryock, who accompanied me and made a more extended 

 stay in the vicinity. 



Carpodacus purpureus. — Several seen. 



Dendroica pensylvanica. — Common in the clearings and second growth. 

 A young bird in the first plumage was secured. 



Dendroica caerulescens.— Tolerably common in oak and hemlock woods 

 bordering a deep ravine. 



Sylvania canadensis. — Common in the rhododendron thickets. Mr. 

 Shryock secured a nest and set of eggs. 



Turdus aonalaschkae pallasii. — One specimen secured. The elevation 

 and location of the Pocono plateau is such as to warrant a fauna quite as 

 boreal as that found at Harveys Lake and North Mt., 1 but the virgin forest 

 has been entirely cleared away in the vicinity of Mt. Pocono and with it 

 have disappeared the northern species of birds, a few only remaining in 

 the deep ravines where they still find a congenial home in the rhododen- 

 dron thickets, and the scant growth of hemlocks which escaped the lum- 

 berman's axe. 



That the fauna of the Poconos was once quite as rich in boreal forms as 

 the northern Alleghanies is shown by the fact that a few miles beyond 

 Tolyhanna Mills (northwest of Mt. Pocono), where there still remains a 

 portion of the virgin hemlock forest, my friend, Mr. Stewardson Brown, 

 found (July 24, 1S93) the Junco and Winter Wren in addition to the species 

 above mentioned. Mr. Brown also observed a large flock of Red Crossbills 

 at Tolyhanna, and in a clearing near the hemlock tract, he is positive he 

 heard several White-throated Sparrows singing. As Mr. Brown is 

 thoroughly acquainted with this bird he could hardly have been mistaken, 

 but it is unfortunate that he was unable to secure a specimen, as this is, 

 so far as I am aware, the first record of the occurrence of this species in 

 Pennsylvania in the breeding season. — Witmer Stone, Academy of 

 Natural Sciences, Philadelphia, Pa. 



Ten New Birds for Colorado.— During the past few weeks I have had 

 the pleasure of examining several small collections of stuffed birds that 

 had been taken in Colorado and find among them several species that 

 have never been formally ascribed to the State. 



Larus Philadelphia. Bonaparte's Gull. — One at Denver and one at 

 Colorado Springs. There is a slight doubt about the one at Denver hav- 

 ing been captured in Colorado.
