AXOTHER EORTXKIHT (IX THE EARALLOXES 
ISl 
22. Empidonax difficilis difficilis. Western Flycatcher. One taken and 
another seen near the siren on May 29th. 
23. Empidonax trailli trailli (?). Traill (?) Flycatcher. An unknown Einpi- 
doiiax, certainly not difficilis, was seen on the 29tli in company with a Western 
WoodPewee, but it could not be secured.

down on the 1st of June and secured on the 2nd, is recognized by Mr. Grinnell as

belonging to his recently elaborated form from the northern interior. Its occur- 
rence so far west of its normal range is certainly of intere.st. 
26. Carpodacus mexicanus frontalis. House Finch. Encouraged by the 
shelter of the cypress grove and Mr. Rosendale’s tiny garden, a small colony of 
these finches have maintained theimselves for some years past. Several broods 
were being successfully reared at the time of our visit, although the busy house- 
holds of the cypress grove were visibly embarras.sed over the presence of so much 
unexpected “company” from the Pjast and South. 
27. Passer domesticus. English Sparrowv More unwelcome than harpies at 
the feast of Ulysses, these wretched interlopers have invaded this sanctuary also. 
Small companies of them from San Francisco visit the islands yearly and return
