These residents on San Benedicte and Clarion show characters that would seem to war- rant their separation as a new race, and this has been done for the bird from Clar- ion Island, a but based upon a single specimen only, in worn plumage; all the spec- imens collected by our party being also in badly worn condition it is impossible to say definitely what the status of these island birds really is until they are taken in fresh breeding plumage. Sturnella magna neglecta (Au?).). Western Meadowlark. A few seen on Todos Santos Island March ?oth. Icterus paris0rum BONAP. Scott Oriole. Common about San Jose del Cabo April 23rd.

Carp0dacus mexicanus ruberrimus RIDGW. St. Lucas House Finch. Abundant about San Jose del Cabo April 23rd, with fresh eggs at this date. Carp0dacus ampius RIDGW. Guadalupe House Finch. Abundant on Guada- lupe Island, nesting principally in the cholla cactus (Ofi?nliaprolifera Engl.). We took sets of eggs that were fresh on March 22nd. This bird seems well protected from the ravages of the cats that are thinning the ranks of the petrels and juncos, due to its habit of building the nest in the cactus, thus making the nest inaccess- ible to the felines even though it be but eighteen inches from the ground. Carp0dacus mcgreg0ri ANTHONY. McGregor House Finch. Taken on San Ben?to Island March 27th and on Cerros Island April ?st; this species, never com- mon anywhere, is practically extinct now.
