Remarks. — The type-locality of T. m. clarus Berl. & Hart, is Bartica 

 Grove, British Guiana, and not Altagracia, Venezuela, as stated by 

 Oberholser (Proc. U. S. N. M., 1904, 27, p. 206). The range of T. m. 

 clarus, according to Hellmayr (Nov. zool., 1905, 12, p. 270; 1906, 13, 

 p. 6), extends from Trinidad and the Orinoco region, through Cayenne, 

 to Para. Berlepsch (Nov. zool., 1908, 15, p. 107) records ten speci- 

 mens from Cayenne, which he calls T. m. clarus. If the Cayenne and 

 Para specimens have been carefully compared with type-specimens, 

 and are really the same, then our bird must be an extremely local 

 form inhabiting the low coastal region of Surinam. In all evertts, 

 we find it impossible to reconcile our specimens to either of the two 

 forms with which we have compared them.
