BIRDS OF WESTERN COLOMBIA. 1101 



This new subspecies is most nearly allied to typical E. xantho- 

 gaster, from Brazil, Peru and Ecuador, but difters in its generally 

 smaller size, especially shorter and. smaller bill. The males, too, 

 have the underparts much clearer chrome-yellow, without any 

 trace of the orange tinge which is always well pronounced along 

 the middle line in the eastern race ; the females also may be 

 distinguished by the nearly pure cinereous instead of bufi'y grey 

 colour of the throat and breast, and by having the middle of the 

 abdomen much paler buffy. Forehead and crown, in the males, 

 are clear chrome-yellow, as in average specimens of xanthog aster. 



E. xanthogaster brevirostris Bonap. *, from Bogota, is much 

 larger (wing 64-65 ; tail 38-40 ; bill 9 mm.), has the foreneck 

 and middle of the belly tinged with orange, and the occiput of a 

 deep brownish orange colour. E. x. hrunueifrons Chapm. t, from 

 South-eastern Peru, is of the same size as brevirostris, but the 

 crown is still darker, dull orange I'ufous. 



The new form has been compared with large sei'ies of the 

 various races. Besides the thirteen specimens in the Munich 

 Museum, I had before me twelve from the Berlepsch Collection, 

 and three belonging to the Vienna Museum.

This species was discovered by the late T. K. Salmon at Jerico, 

 south of Medellin, on the left side of the Cauca River, in the 

 Western Cordillera of Colombia. Dr. Sclater described and 

 figured the adult male. Specimens transmitted by the late J. 

 H. Batty from Riolima (Cauca Valley) agree perfectly with the 

 original description. 



The immature male and female difl'er in lacking the lemon - 

 yellow interscapulium (which is mainly green with but a faint 

 yellowish tinge) and in having the middle of the belly dull grey 

 instead of black. Moreover, the general colour is not so bluish. 



C. nitidissima is apparently restricted to the Western 

 Cordillera of Colombia, and found only at altitudes above 

 ,5000 feet.
