secured, of which four were taken in decayed stumps, and the fifth in 
a runway under a log. 
Sitomys americanus.—A young male and female in plumbeous gray 
pelage, with a narrow streak of brown on the flanks were the only 
ones collected. 
Arvicola pinetorum.—T wo specimens were secured under a log. 
Zapus insignis.—An adult male of this handsome mouse was secured | 
July 4th, on the bank of a stream in a ravine covered with a growth 
of hemlocks and laurels. 
Tamias striatus lysteri-We found this chipmunk quite common 
among the rocks and young growths where the timber had been 
recently destroyed by fire. The specimens collected, on comparing 
them with skins from Maine, were found to be typical /ysteri. 
Seiurus hudsonius——A tolerably common species. A suckling 
female, shot on June 29th, is an interesting specimen as showing à 
peculiar phase of the molt. The long winter coat is considerably 
bleached on the upper parts and sides; and from the nose toa line 
drawn across the head just back of the ears, npon the anterior margin 
and extreme tip of the ears, and for a space upon each shoulder it is 
entirely replaced by the new growth of shorter yellowish rusty hairs 
annulated with black. The bright chestnut of the dorsal region, 
besides being very much worn, is interrupted just behind the shoul- 
ders, by an irregular patch of the new hair, in which the black pre- 
dominates. The sides of the head and neck as far forward as 
roots of the whiskers, the greater surface of the ears, a space on the 
back of the head, and the entire posterior portion of the body still 
retain the old pelage.— Wm. A. SHRYOCK. 
The Mammals of Thibet.—-Several French travellers have 
explored China, Mongolia, Thibet and Indo-China, and their reports 
are full of interest. Every naturalist knows of the brilliant discover- 
ies made 25 years ago by M. ’abbé Armand David; they wer le 
tions of the richness of the Thibetan fauna. Since that oe M. 
Dr. Harmand, M. Pavie, M. Joseph Martin, le prince Henri d on 
and M. G. Bouvalot, M. Dutreuil de Rhins and the French po 
aries of Tatsi-en-lou, directed by M-go Biet, have contributed muc 
our knowledge of the natural products of central and eastern eee

number of mammals and birds, the former of which forms the "i
