a bird of the Subtropical Zone, its range is cut off at Panama by the 

 low country), I am inclined to follow Doctors Hellmayr and Chap- 

 man in according it only subspecific rank, for the present at least. 

 It was described by Lawrence from a Costa Rican specimen collected 

 by Carmiol, and later discovered in Veragua by Arce, the receipt of 

 whose specimens led Salvin to identify it with the Bamleuterus hlvit- 

 tatiLS of Lafresnaye and D'Orbigny, with which it of course has 

 nothing to do. Mr. Carriker says that in Costa Rica it is rather a 

 rare bird, "the least common of the genus," which will account for 

 its not being common in collections.

Remarks. — This species has until lately been known only from the 

 single pair of birds collected by M. Stolzmann at Callacate, in north-

 Unfortunately enough, the types were among those which were lost 

 at the time of the attempted transfer of all such material in the War- 

 saw Museum to Russia during the World War, as I am advised by 

 M. Stolzmann himself. Doctor Chapman thinks that his examples
