of B. arccei, differing in having the sides and flanks uniformly and ex- 

 tensively dusky-bluish. Three birds of the above series are apparently 

 adult, being much more brightly colored than the rest. They measure 

 as follows: 



Wing. Tail. Culmen. 



Car. Mus. 25794 cf ad. Carrillo, Aug. 17, 1905 91 48 15.5 mm. 



Car. Mus. 25803 c? ad. " 20 88 53 15.5 mm. 



Car. Mus. 25841 c? ad. " 22 " 91 51 16 mm. 



None of these birds, however, show as distinct a blue color on the throat 

 as on the crown. No. 25803 differs from all the others in having the 

 yellow area of the chest flecked with black." (W. E. C. Todd.) 



This is one of the rare tanagers of Central America, being confined 

 (so far as now known) to the northeastern portion of Costa Rica, around 

 the northeastern slopes of the Volcanoes Turrialba, Irazu, Barba, and 

 Poas, from an altitude of about 1,000 feet up to 4,000 feet (Hondura). 

 It is rare so high as La Hondura, but one specimen having been taken 

 there. It is found only in the dense, tangled jungles of the rain-soaked 

 Caribbean foot-hills, keeping near the ground in the most impenetrable 

 parts of the undergrowth. I never heard the bird sing, but it has a tanager- 

 like call, or note of alarm, resembling that of Caryoihraustes or Phceni- 

 cothranpis.
