1110 MR. C. E. HELLMAYR OX THE 



blue (Viilette's Code ties Couleurs, no. 417) ; lesser and median 

 Tipper wing-coverts uniform bright indigo-blue (in shade between 

 nos. 411 and 412 of Valette's Code), forming a large pale blue 

 shoulder- patch ; greater series dusky, on the outer web washed 

 with dull bluish; primary coverts, remiges and rectrices blackish, 

 narrowly fringed with dull bluish along outer margin. Below : 

 throat and sides of breast deep black, like the back ; flanks duller 

 and inclining to blackish slate-colour ; rest of under parts bright 

 saftVon -yellow, passing into a deeper, more orange tinge on the 

 middle of the chest. Axillaries pale yellow, under wing-coverts 

 yellowish white. 



Bill uniform black. " Iris brown, feet black." 



Wing 90; tail 53; bill 15| mm. 



Mr. Palmer obtained a single specimen of this distinct species 

 on the San Juan slopes of the Western Cordillera. It belongs to 

 that section embracing B. arccei Scl. ife Salv.* and B. rothschildi 

 Berl.t, but differs conspicuously in coloration. The most im- 

 portant characters of B. inelanochlamys are the bright, pale blue 

 shoulder-patch, altogether absent in both of its allies, and the 

 deep black colour of the head, mantle, and scapulars, without any 

 bluish tinge. B. arccei resembles it in having the breast and belly 

 bright yellow, but the sides and flanks, instead of being exten- 

 sively uniform deep black, are merely clouded with dusky, and 

 the upper parts as well as the throat are strongly glossed with 

 dai'k purplish blue. B. rothschildi, from the, foot-hills of North- 

 western Ecuador, has, like the new species, the head and throat 

 deep black ; however, the back, scapulars, upper wing- and tail- 

 coverts are conspicuously glossed with purplish blue, while the 

 under parts, with the exception of an orange-yellow patch on the 

 foreneck, and the lemon-yellow anal region and under tail-coverts, 

 are black, with a more or less distinct pui'ple-bkie sheen. 



The bill is deep black in all three species which eventually 

 will prove to be geographical representatives. Their range is 

 singularly restricted : — 



(a) B. arccei Scl. & Salv. inhabits the Cordillera del Chucii, 

 Vei^agua. 



(b) B. 'inelanochlamys Hellm. is found in the Western Cordillera 

 of Colombia, on the sources of the San Juan River. 



(c) B. rothschildi Berl. is met with in the foot-hills of North- 

 Western Ecuador : Cachabi (450 ft.), Rio Pichiyacii (500 ft.), etc.
