Mr. McGregor further state? that on the?e islands '•' the San Benito Sparrow 

 far outnmnbtrs all other land bir«.ls taken together." He examined three dif- 

 ferent nests, all of which were placed on the ground under small bushes. 

 One found on March 30 contained three eggs. It " was sunken level with the 

 ground, which served to support the thin walls. The outside is of large grass 

 straws while the lining is of finer grass and a few feathers. The three ejsrs 

 measure respectively .S3 X .58, .52 X .61, .81 X .60. They were slightly incu- 

 bated [when taken on April 1]. They are well marked all over with flecks 

 and blotches of umber brown on a ground color of faint bluish white. One 

 egg has one or two blackish hair lines on the large end."'

The birds collected by Mr. Frazar have rather stout bills for biiimculaius, but 

 they are typical of that form in respect to coloring and to the relative lengths 

 of their wings and tails. 



Mr. Btrlding gives this sparrow as " rare," but states that he rslw it in several 

 localities. Mr. Frazar took only four specimens, two at San Jose del Cabo on 

 October 21 and 27, respectively, and two at Triunfo on December 5 and 15. 

 Jfo one else has reported the bird from the Cape Region, nor does it seem to 

 have been detected elsewhere on the Penin.'ula. It has occurred at various 

 places in California, and in the summer of 1875 was found by Mr. Henshaw 

 breeding at Santa Barliara directly on the coast. Most of the birds which 

 visit Mexico and Central America in winter are said to be passerinus, but 

 Salvin and Godman. mention ^ a Mexican specimen which, is " as pale as 

 another, marked by Mr. Eidgway himself as C. perpalUdus."
