tw^s Oberholser [now called con^ectus'], of the adjacent mainland, 

 but averaging darker dorsally (more sepia and not so umber brown), 

 and with heavier bill and conspicuously and constantly larger feet 

 (longer toes and heavier tarsus) ; differs from T. h. leucophrys (An- 

 thony), of San Clemente Island, in decidedly darker, less ashy colora- 

 tion, and in much more heavily barred under tail-coverts; differs 

 from 2\ h. nesophilus Oberholser, of Santa Cruz Island, in duller, less 

 rufescent, coloration, grayer flanks, longer bill and generally larger 

 size." 



He says that it is common on Santa Catalina Island and permanently 

 resident. It does not seem to differ in any of its habits from the main- 

 land forms of the species. 



There is a set of six eggs of this race in the collection of Charles E. 

 Doe, of Gainesville, Fla. It was taken by J. S. Kowley on Santa Cata- 

 lina Island, May 8, 1920. The nest was in a crevice of the "bark of 

 a scrubby-like bush in the bottom of a gulch." 



The eggs in this set and five more in the Philipp collection, 11 in all, 

 average in measurements 17.6 by 13.2 ; the eggs showing the four ex- 

 tremes measure 18.3 by 13.5, 17.6 by 13.6, 16.8 by 13.0, and 17.8 by 12.7 

 millimeters. 



THRYOMANES BEWICKII LEUCOPHRYS (Anthony) 



SAN CLEMENTE WREN 



HABITS 



A. W. Anthony (1895a), with Dr. Edgar A. Mearns, collected a 

 series of Bewick's wrens on San Clemente Island, off the extreme 

 southern coast of California, from which this wren was described 

 and named as a new species. Mr. Anthony describes it as "differing 

 from T. spilurus in decided gray wash on the upper parts, in the 

 less heavily barred under tail-coverts, and in having a somewhat 

 longer bill." He says further : 



Although the present species is obvioiisly closely related to the mainland 

 bird, * * * I gee no reason at present for regarding it as a subspecies of 

 that form. San Clemente Island lies 75 miles from the mainland, and it is 

 quite evident that the species does not intergrade through the other islands of 

 the Santa Barbara group, as the Thryothorus from those islands proves to be 

 no nearer related than does the mainland form. 



The differences are at once noticeable even at a glance ; the longer bill, the 

 more purely white and much more conspicuous superciliary stripe, together 

 with the more gray upper parts arc quite striking to one acquainted with the 

 mainland bird. The species is quite common in the thick cactus and low brush 

 on the south end of the island, but owing to its habits is quite difficult to 

 secure. 



A. Brazier Howell (1917) writes: 



These wrens are evenly distributed over San Clemente, frequenting the densest 

 thorn bushes and cactus patches, from the tops of which their loud clear song, 

 differing but little from that of the mainland bird, is given. Before one is within
