Two specimfins : 



a. 9, March 23, 1904. 



b. Chichen-Itza, Feb. 5, 1890, E. H. Thompson (Pablo Perera). 



Not common. The specimen taken by me appeared to be rather small and 

 pale, but Mr. Nelson, who examined it, writes : "A number of specimens of 

 Sittosomus in our collection from Yucatan show that the birds from that region 

 are not distinguishable from those from elsewhere in Mexico." Specimen b 

 agrees with my specimen in coloration, but is a little larger.

Wood Hewer. 



Maya name, ta-tortsel. 



Five specimens :

 Chapman reports this bird as " tolerably common," but I found it rather 

 scarce.

Maya name : Boucard (Proc. Zool. Soc. Lond., 1883, p. 448) gives the Maya 

 name of this bird as " Stachi." Without the feminine prefix it should prob- 

 ably be written ta-tsai' or ta-kai'.
