Grinnell, Catalina Island Quail.

Measurements. — In millimeters; the difference in dimensions be- 

 tween males and females of L. c. vallicola is so minute, that the two sexes 

 are lumped together. 



Remarks. — The bulkiness of catalinensis is at once apparent 

 when one sees it among specimens of the mainland vallicola. The 

 tail is particularly long, the rectrices being proportionately broader. 

 The bill is heavier, and the toes and tarsi decidedly stouter. These 

 characters hold equally in the males and females. In coloration 

 catalinensis shows a deepening of shades especially on the lower 

 surface. In both sexes the flanks and lower tail-coverts are more 

 broadly streaked with brown; the terminal black edgings of the 

 lower breast feathers are broader, and the light markings beneath 

 are suffused with deeper ochraceous. Especially in the female of 

 catalinensis is the lower surface darker tjian in vallicola, due to the 

 encroachment of the dark portions of each parti-colored feather 

 upon the light part. The dorsal surface is not however much 

 browner than in vallicola — ■ it is decidedly slaty as compared with 

 the deep bright Vandyke brown of califomicus from the vicinity 

 of San Francisco Bay. 



Mr. H. C. Oberholser comments (Proc. U. S. Nat. Mus., XXII,, 

 1900, p. 229) on "one male and one female from Santa Catalina 

 Island. They seem rather darker and more ochraceous than 

 extreme - examples of vallicola, but are identical with birds from 

 the San Joaquin Valley. The species has probably been intro-
