This species (founded upon a single skin) appears to be a desert 

 form of the preceding, differing in having the general colour of the 

 upper parts a pale greyish brown, slightly darker on the centre of 

 the feathers of the head ; the axillarics and beUj- are pale buff, 

 slightly darker on the flanks and sides of the breast ; chin and 

 throat white, streaked with greyish brown. Length of wing 5-1 

 inches, tail 3"6, culmen 0-95, tarsus 1'25. Wing-formula the same 

 as in the preceding. This supposed species may probably prove 

 to be only an unusually pale example of the common one — in fact, 

 an accidental varietj\ 



The only example known of the Cape-St.-Lucas Eobin-Thrush 

 was obtained at Todos Santos, in the extreme south of the Califor- 

 nian peninsula. 



The above description is taken from the type in the museum 

 of the Smithsonian Institution in Washington.
