Carriker : List of the Birds of Costa Rica. 6 ( .)5 



only subspecifically distinct cannot occupy the same range, according to 

 the definition of a subspecies. 



The series of birds in Mr. Bangs' collection seems to bear out the idea 

 that it is a distinct form, the reasons for which he gives (Proc. Biol. Soc. 

 Wash., XXII, 1909, 34). I have also examined them and am of the 

 same opinion. 



M. brachyurus is found in Costa Rica only in the northwestern portion 

 of the country, principally in the Tempisque basin and around the shores 

 of the Gulf of Nicoya.
