66 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
What the summer dress is like I am not prepared to state, but I have reasons 
for suspecting that breeding examples of the eastern and western (or interior) 
forms are not easily distinguishable from one another. I was at first inclined 
to think that the bird which I have named frazart was merely the adult of 
melanoleucus in winter plumage, but a careful examination of Mr. Frazar’s 
specimens has satisfied me that several of them are young, and on comparing 
them with a good series of both adults and young of melanoleucus, shot at corre- 
sponding dates in New England, I have become convinced that the differences 
to which I have just called attention cannot be satisfactorily explained other 
than by the assumption that they characterize two distinct geographical races. 
A rather puzzling feature of the case is that I have several specimens perfectly 
typical of melanoleucus from British Columbia, and a dozen or more equally 
characteristic of frazari from Georgia and Florida, but birds of such free powers 
of flight as Yellow-legs are notorious wanderers, and it may be that frazara 
breeds only in the ¢ntertor of British America and that it does not visit either 
the Atlantic or Pacific coast until it has passed well to the southward of the 
northern boundary of the United States. 
This hitherto unrecognized form of the Greater Yellow-legs is, no doubt, the 
bird which Mr. Xantus found at San José del Cabo (December) and Cape St. 
Lucas (date not recorded), which Mr. Belding gives as “very common in 
winter ” south of latitude 24° 30’, and which Mr. Bryant reports as “tolerably 
common along the estero” north of Magdalena Bay and also “seen about fresh 
water at Comondu and San Pedro.’’? Mr. Frazar noted a single bird at La Paz 
on March 21, and between September 19 and October 20 collected fourteen 
specimens at San José del Cabo, where, however, he did not meet with them 
in any great numbers. His latest record at this place is November 9, when 
two birds were observed. 
Totanus flavipes (GmEL.). 
YELLOW-—LEGS. 
Although the Yellow-legs has not been previously recorded from any part 
of Lower California Mr. Frazar found it much more numerous than 7’. melano- 
leucus frazart. It was, however, observed only at San José del Cabo where it 
became common as early as August 28, but did not reach its maximum abun- 
dance until the middle of September, when upwards of two hundred were 
sometimes seen in the course of a single day. After September 20, its num- 
bers rapidly diminished and the last bird was taken on October 7. 
This Yellow-legs winters as far south as Patagonia and breeds in the Arctic 
and Subarctic portions of North America.
