Parkuiau's Wren is included without comment by Mr. Belding in his 

 list of birds " common to most or all of the localities where collections were 

 made" "near the southern extremity of the Peninsula." Mr. Bryant also 

 gives it as a bird of Lower California, but apparently solely on the autliority 

 of Mr. Belding, who, he states, " found it to be rare on Cerros Ishxnd, and col- 

 lected a specimen at La Paz." .Mr. Anthony mentions only T. a. aztecus, 

 which, he says, was "abundant in the pines " on San Pedro Martir in late 

 April and early May, 1893. ^ 



Mr. Frazar's collection contains five House Wrens, of which two were taken 

 at San Jose del Cabo on September 29 and October 17, respectively, one 

 at Triunfo on December 9, and two at San Jose del Rancho on December 

 20 and 21, respectively. All of these birds seem to me to be referable to 

 aztecus. They are certainly quite as ashy as average examples of that form, 

 although in respect to the nearly obsolete character of the barring on the upper 

 parts, they agree rather better with parkmanii. 



From this it will aj^pear that the status of the House Wrens which occur in 

 the Cape Region in autumn and winter is still open to doubt. It is quite 

 possible, of course, that some of them are really examples of parkmanii which 

 migrate southward from California, but more probable, in my opinion, that 

 most if not all of them are representatives (not quite typical, perhaps) of 

 aztecus, which pass their summers at San Pedro Martir and other elevated places 

 in the more northern portions of the Peninsula. 



Cistothorus palustris paludicola Baied. 

 TuLE Wren.

Mr. Belding gives this Marsh Wren as "rare " in his list of species found at 

 San Jose del Cabo from A]u-il 1 to May 17, 1882. The birds which he saw on 

 this occasion were probably only belated stragglers from the hordes which
