This is the true C. I. fanny which was originally described from 

 specimens obtained by Delattre in the same district of Western 

 Colombia. The comparison of these birds with the large 

 series in the Munich Museum clearly proves that the Central- 

 American form has beeia wrongly referred to C. I. fanny by 

 Sclater, Ridgway, and others. C. I. favny as represented by 

 specimens from Western Colombia and N.W. Ecuador (which 

 are exactly similar) is an exceedingly well characterized race. The 

 greater upper wing-coverts and the remiges are either uniform 

 black or show only the faintest trace of greenish fringes in their 

 apical half ; the lower back and rump are very pale sky-blue ; the 

 blue frontal patch is very strongly developed, reaching as far as 

 the posterior edge of the eye ; the flanks are washed with pale 

 sky-blue, without any purple-blue admixi.iu'e ; the bill is small 

 and slender. Birds from Ohiriqui and S.W. Costa Rica (Guana- 

 caste, Pozo Azul de Pirris), however, differ at a glance in having 

 the greater wing-coverts and remiges very distinctly margined 

 with pale green, and the flanks much more extensively and darker 

 blue, with a strong purplish blue tinge anteriorly. Moreover, the 

 blue frontal patch is much more restricted, never reaching further 

 back than to above the middle of the eye, and the bill is larger 

 and stouter. In all of these points they agree with C I. larvata 

 Dubus*, of which we have a fair series fi-om Guatemala and 

 Eastern Costa Rica (Carrillo), but may easily be distinguished 

 from that form by their coppery-golden, instead of deep coppery 

 reddish-brown thi'oat, much paler blue cheeks with very little 

 purplish tinge, and slightly paler blue rump. 



G. I, fanny is restricted to the forest-belt bordering the Pacific 

 coast, ranging from N.W. Ecuador (Cachabi, S. Javier, PambiUr) 

 to Turbo, on the Gulf of Uraba, N. Colombia.
