Nov. 1907. BIRDS FROM GUATEMALA DEARBORN. 137 



of Guatemala, between the Cordillera and the Atlantic lowlands, and 

 also in the similar region of western Nicaragua. Eight specimens 

 from Nicaragua in this Museum, six from San Geronomo, Chinandega, 

 one from San Rafael and one from San Emilis, Lake Nicaragua, are 

 all indistinguishable from Tampico specimens taken in the same 

 month April. This thrush frequents trees about cultivated land, 

 and in March and April its song was heard daily on the plantations. 

 None were seen above 5,000 feet. In the dry regions they were found 

 only along streams where trees retain their foliage the year round. 

 Iris brown; bill yellowish green. 



301. Planesticus tristis leucauchen Sclater. 



Two specimens were taken at Los Amates late in January. They 

 are not quite typical as to color, being more olive above, less cinereous, 

 than specimens from Vera Paz and western Belize, where the ashy 

 phase of tristis seems to culminate. It may not be out of place here 

 to call attention to the fact that there is a skin in this Museum ex 

 Boucard, collected in Guatemala, which agrees exactly, as to color, 

 with a topotype (*) of cnephosa Bangs and is even smaller. 



In his original description of cnephosa, Mr. Bangs makes "smaller 

 and darker" the characters that distinguish it from leucauchen of 

 Guatemala. As a matter of fact typical leucauchen is darker than cne- 

 phosa, ("Supra nigricanti-cinereus" Sclater) . There is, indeed, little 

 to choose between leucauchen and cnephosa as a name for Los Amates 

 specimens, and it may yet turn out that the latter name is applica- 

 ble to them. This bird was found only in the dense woods, where it 

 was apparently not at all common. Iris brown; bill straw-color; 

 eye-ring yellow; feet pale.
