« Ten specimens. 



!> Four specimens. 



« Several of the specimens examined show more or less speckling of dusky on the 

 lower abdomen, a feature which I find in only one example of a much larger series 

 of T. s. sinaloa, and in that indicated but slightly. Two of the supposed characters 

 of T. s. cinereus mentioned in the original description, stouter bill and grayer under 

 parts, I am unable to verify. 



<i Seven specimens.
