is not so loud. Their note of alarm is a loud and ringing chirp, repeated and answered by others at

** At Santa Cruz, on the 1st of June, Dr. Cooper met with several of their nests, which, though 
De probably erroneously, he supposed to belong to the Dwarf Hermit-Thrush. They were all built in 
thickets under the shade of cottonwood-trees. Each nest was about five feet from the ground, and all 
contained eggs, from two to four in number, in differing stages of incubation. Тһе nests were built 
of dry leaves, roots, fibres, grasses, and bark, without any mud, and were lined with decayed leaves. 
ih Their height and external diameter measured 4 inches. Тһе diameter оҒ the cavity was 21 inches 
and the depth 21. Тһе eggs measured "90 by “70 of an inch. They are of a pale bluish-green, 
T speckled with cinnamon-brown, chiefly at the larger end. 
Y “Тһе nest, supposed to be of this species, supplied by Dr. Cooper, is large for the bird; con- 
T structed of a base loosely made up of mosses, lichens, and coarse fibres of plants. It is a strong and 
be compact structure of matted leaves, put together when in a moist and decaying condition; with these 
EL there are interwoven roots, twigs, and strong fibres, surrounding the nest with a stout band and strength- 
E ening the rim. In fact, it corresponds so well—as do the eggs also—with those of Т. ustulatus, that 
м it is extremely probable that they really belong to that species. The only observable difference is the 
^" absence of the Hypnum mosses characteristic of the northern 7. ustulatus. The fact that this Thrush 
builds its nest above the ground and lays spotted eggs, if verified, would at once warrant our giving 
1t independent rank as a species, instead of considering it as a local race of Т. pallasi.” 
Turdus aonalaschke is a small form of T. pallasi, with a slenderer bill. It is also of a darker 
reddish-brown colour above, and the upper tail-coverts and tail are ferruginous-brown, not very 
different in tint from the tail of 7. pallasi. It is darker than that species on the sides of the body, 
which are deep ashy-grey or mouse-brown. Тһе under wing-coverts, however, are much darker than 
in T. pallasi, and are nearly uniform ashy-brown like the axillaries and flanks ; the axillaries 
are white near the base. The spotting on the throat is larger than in 7. pallasi, and frequently clouds 
the whole throat and chest, while the spots on the breast are larger and much more pronounced. 
The adult male measures :—Total length 6:3 inches, culmen 0:6, wing 3*5, tail 2:65, tarsus 1-2. 
The adult female measures :—Total length 6:1 inches, wing 3'6. “Bill dark brown, yellowish at base 
of lower mandible ; feet райе brownish ; iris brown” (W. Brewster). 
Mr. Seebohm did not figure this race. [R. В. S.]
