FAMILY MOMOTIDAE 441 



Beyond Panama this race ranges in northwestern Colombia in north- 

 ern Antioquia (Dabeiba, Villa Artiaga, Valdivia) and western 

 Cordoba (Socarre, Ouebrada Salvajin). These Colombian specimens, 

 collected between 1948 and 1950 by M. A. Carriker, Jr., may be 

 regarded as typical of the race in the amount of dark coloration. 

 The type, and the rest of the series from Panama average somewhat 

 paler, and are thus intermediate toward nominate momotula, but are 

 to be placed with the darker group. 



Hylomanes momotula momotula Lichtenstein is not only lighter 

 on the breast and foreneck, but averages whiter on the abdomen. 

 In earlier studies on a collection of birds from northwestern Costa 

 Rica (Proc. U. S. Nat. Mus., vol. 95, 1944, p. 51) I identified 2 

 specimens collected on the Cerro Santa Maria, Guanacaste, as the 

 race obscurus. With the additional material typical of this southern 

 form now available I find that this was incorrect, and that these 

 belong with momotula. That form, therefore, has a range extending 

 from southern Mexico to northwestern Costa Rica. Another race 

 H. m. chiapensis described by Brodkorb from the Pacific slope of 

 Cerro Ovando, Chiapas, needs further study to clearly determine 

 its distinctive characters.
