in other characters they are hke Arizona specimens. In central 

 western Texas the birds are as small as Dryohates scalaris symplectus,^ 

 but in color are just like D. s. cactopMlus, so, since color is the most 

 reliable distinction between these two forms, these intermediates 

 belong with the latter. 



Birds from New Mexico and Chihuahua are likewise slightly smaller 

 than those from Arizona. In northeastern Lower California and in 

 southern California north to Palm Springs and Needles there occur 

 occasional specimens which have no black bars on the outer web of 

 the outermost long rectrix, indicating intergradation with Dryohates 

 scalaris eremicus; and the writer himself in times past has identified 

 some of these as Dryohates scalaris lucasanus (i. e., D. s. eremicus). 

 In the same regions, however, there are also birds with this feather 

 fully barred; and all have tlie lighter colored upper parts and other 

 characters of Dryohates scalaris cactopMlus, to which race it is now 

 evident that they belong. This disposition makes it necessary to 

 expunge Dryohates scalaris lucasanus (i. e., Dryohates scalaris eremicus) 

 from the list of California birds.
