SELASPHORUS ALLENI Henshaw. 



Two adult males in perfect plumage, from Santa Catalina Island are 

 identical with Nicasio birds. 



SAYORNIS NIGRICANS (Swainson) . 



Three birds from Santa Cruz Island are all immature, with rufous 

 edgings to the feathers of lower back, under wing-coverts and all the 

 upper series ; the innermost secondaries are also margined with a paler 

 shade of the same. Two adults taken on Santa Eosa Island add the 

 species to the fauna of this island. 



EMPIDONAX INSULICOLA Oberholser. 



Five specimens; from Santa Eosa, Santa Cruz, and Santa Catalina 

 islands; all mentioned in the original description of the species.^ Since 

 that was published, the writer, through the courtesy of Mr. Joseph 

 Grinnell, has examined specimens from San Clemente Island, which are 

 substantially identical with those from the other islands. 



OTOCORIS ALPESTRIS INSULARIS Townsend. 



Twelve examples from San Miguel Island and one from Santa Eosa 

 are all in more or less worn plumage, but even in this condition exhibit 

 the distinctive characteristics of this insular race. 



APHELOCOMA INSULARIS Henshaw. 



A fine series of twelve adults and five immature specimens serves 

 very strongly to emphasize the distinctness of this species from both 

 of its mainland relatives. Not only are its characters very pronounced, 

 but among perfectly comparable examples there is relatively little 

 individual difference either in size or color. Many of the adults are 

 strongly tinged with brownish below, but this is undoubtedly an 

 adventitious stain, as it is absent on feathers of the fresh plumage. 

 All the adults are in process of molt and exhibit almost every stage 

 of feather renewal. The immature birds are all in "first" plumage, 

 just beginniDg to change into perfect dress, and differ little from each 

 other. The j)lumage of the young, which seems never to have been 

 described, is as follows : 



Above chocolate brown, shading into dull dark blue on crown and 

 upper tail-coverts, the transition on latter rather abrupt; wings and 

 tail as in the adult; sides of head and neck blackish brown; a short 

 whitish line over each eye, the only indication of a superciliary; chin, 

 throat, and center of jugulum brownish white, the sides of jugulum 

 and an almost complete collar on breast dull blackish brown ; remainder 

 of breast and abdomen smoke gray; crissum dark slate gray; thighs 

 light brown.
