must regularly winter at this place, for in the autumn of 1887 Mr. Frazar 
found Tulé Wrens in immense numbers both here and at Santiago. They 
evidently came from the north, the vanguard of the flight arriving on Septem- 
ber 21 (a single bird was seen on the 14th), but the bulk not until October 
19, after which their numbers increased slowly but steadily up to November 
4, when they simply swarmed in the patches of tall rushes and tules along the 
river. They were particularly abundant at Santiago, on November 22. A 
very few were seen at San José del Rancho in December, but none about La 
Paz in January, February, or March. To the northward Mr. Bryant has ap- 
parently met with only two specimens, both on Santa Margarita Island. 
C. p. paludicola is very common, coastwise, in California wherever it can find 
suitable haunts. It is resident in the southern and central parts of the State 
and it winters sparingly as far north as Washington and Oregon, while its 
breeding range extends into British Columbia. It is said to migrate as far 
south as Guatemala.

Cistothorus palustris plesius OBERHOLSER, Auk, XIV. 1897, 186-193 (orig. descr. ; 
types from New Mexico and Utah; typical examples from Miraflores). 
Mr. Oberholser says! that “very typical specimens of plesius have been 
taken at Miraflores, Lower California,’’ but at what season he does not state. 
The large series of Marsh Wrens collected by Mr. Frazar at San José del Cabo 
includes representatives of this race and paludicola in about equal numbers. 
Which of the two birds —if either — is resident in the Cape Region I have 
no means of judging. Nor have I seen enough breeding specimens of either 
to form any definite opinion as to the value and constancy of the char- 
acters by which they have been separated. I may say in this connection, how- 
ever, that I have a number of skins apparently typical of plesiws which were 
obtained by Mr. L. M. Turner late in April, at Seattle, Washington, and hence 
practically on the Pacific coast, where, if I understand the case correctly, 
paludicola should be the breeding form, for plesius, according to Mr. Ober- 
holser, breeds only in the interior.
