20 REVIEW OF AMERICAN BIRDS. [PART I. 
aliciz. One specimen (5,657) from Kansas, has the bill only .30 
from nostril to tip; the tarsi, .99; wing, 3.80; tail, 2.88. In an 
average specimen from Carlisle (2,639) the bill is .40; tarsus, 1.12; 
wing, 3.75; tail, 2.85. 
A specimen from Panama, belonging to Mr. Lawrence’s collection, 
and which he refers to the Turdus minimus of Lafresnaye, is smaller 
than the average of northern specimens, with shorter bill. It is a 
very little less than the Kansas specimen, with the bill a little longer ; 
but several Carlisle and other northern specimens have the wings 
and tail still shorter. I am, therefore, disinclined to consider the 
specimen as anything more than TZ. swainsonii, perhaps a short 
billed variety to which the Kansas specimen may also belong. 
If the Turdus minimus of Lafresnaye be properly described, it 
would appear to be different from any of the varieties of 7. swain- 
sonii. 
This species has been found to occur farther to the west than was 
formerly supposed. Mr. Drexler obtained specimens at Fort Bridger, 
Dr. Cooper in the Bitterroot Mountains, and Dr. Kennerly, of the 
N. W. Boundary Survey, found it in Washington Territory. North- 
ward it reaches almost to the Arctic Ocean, along the Mackenzie, 
and across from there to Fort Yukon; in fact it occurs throughout 
the whole northern heavily wooded region. I have seen no speci- 
mens from Labrador, where, however, 7. aliciz seems abundant. 
Having had the opportunity of examining the specimen from Bo- 
gota, which Dr. Bryant referred to the species of Lafresnaye (no. 92 
of Dr. Bryant’s collection), I am able to corroborate the remarks of 
the former relative to its peculiarities. The spots are larger than 
common in the North American birds, and appear to extend farther 
back on the breast and sides, where, in fact, they are as dark as those 
on the jugulum, instead of being fainter and grayer of tint. The 
flanks are darker, and colored like the back, instead of being much 
lighter. The line from bill to eye, and probably the ring round the 
eye, are of a much more brownish-yellow. 
I am, however, not ready to conclude that this specimen is specifi- 
eally distinct from Turdus swainsonii, as North American skins 
vary a good deal in their characters, some of them approaching 
it in one direction and some in another. The size is nearly equal to 
the average of swainsonii, the skin being pressed up so as to seem 
shorter than it should be. It measures but 5.90, but should be at 
least 6.50; the wing is 3.80; the tail 2.95; bill to nostril, .36; 
tarsus, 1.04; all dimensions readily paralleled in the North American 
bird. The bill is fully as large.
