'^'Iii some specimens of T. m. modestus the middle rectricea are as indistinctly 

 1 tarred as in the present form; but the individual variation with respect to this char- 

 acter in the typical form is very considerable, whereas in the present one the nine 

 specimens are practically alike. The form is not a very strongly characterized one, 

 but the differences, though slight, are apjtarently constant, and on the whole are 

 at least as great as in the case of the Panama form {T. m. elutus), which represents 

 the ojtposite extreme as to coloration. 



^ Five specimens. 



<' Three ipecimens. 



''Tim single specimen from Ilondurus (San Pedro Sula) is in such badly worn and 

 faded pluiiiage tiiat its positive identilii-ition with either form is impracticable.
