* The following race has been recently separated by Dr. Brewster : — 



Geotiilypis occidentalis. 

 Geotblypis trichas occidentalis, Brewster, Bull. Nuft. Orn. Club, yiii. p. 159 

 (1883). 



Adult male. Upper parts nearly uniform pale yellowish olive, with a tinge of 

 brown on the occiput ; throat, jugulum, breast, anterior portion of abdomen, 

 and under tail-coverts rich pure yellow ; sides of body warm ochraceous brown, 

 strongly tinged with yellow ; middle of abdomen anteriorly creamy white ; a 

 black mark on the front and sides of the head bordered behind by a "broad band 

 of creamy white, slightly tinged with bluish; much concealed yellow on the 

 feathers of the crown. Wing 2-32 inches, tail 2'30, culmen 55. 



The differences which distinguish this race from G. trichas proper, although 

 somewhat difficult of description, are readily appreciable upon a comparison of 

 specimens. They may be briefly summed up as follows : — G. occidentalis is some- 

 what larger than G. trichas, and its tail is disproportionately longer ; its upper 

 parts are always paler and usually yellower ; the yellow of the uuderparts is 

 decidedly richer and purer, aud extends much further down on the abdomen, 

 frequently tinging nearly all of the body beneath ; the flanks are paler and more 

 ochraceous; the white of the head purer aud generally broader. {Brewster.)
