Carpodectes nitidus. — A prevsumed young male of this excessively 

 rare species, from Pacuare, Costa Rica, resembles the adult male, except 

 that the terminal half (of the exposed portion) of the primaries is uni- 

 form dusky bhickish, while the secondaries have a considerable part of 

 their concealed portion dusky, the amount decreasing toward the inner 

 ones, the tertials being entirely white; the i)rimary-coverts have also 

 iheir terminal half grayish dusky, while of the alulie one feather on 

 one side and two on the other are of the same color. The rump is also 

 somewhat obscured by a grayish tinge. The pileum seems to be of a 

 deeper shade of fine pearl-blue in this specimen than in an adult male 

 in the National Museum from Nicaragua. Mr. Zeledon's specimen 

 measures as follows: — Wing, 5.40; tail, 3.00; bill, from nostril, .45 ; 

 tarsus, .95 ; middle toe, .85. 



JUNCO VULCANI (Boucaid). — This interesting new species was origi- 

 nally discovered by Mr. Zeledou in 1873, but the specimens which were 

 then forwarded by him to the JSmithsonian Institution, along with other 

 species then new, but since, like the present one, rediscovered, never 

 reached their destination. Specimens more recently collected by Mr. 

 Zeledou are now before me, and upon examination I find that the spe- 

 cies should be referred to the genus Junco, rath r than to Zonotrichia. 

 In fact, it agrees perfectly in its generic characters with the former, 

 excejjt that the back is streaked, while there is no white on the lateral 

 tail feathers. Like J. cincreus of the highlands of Mexico, and J.alti- 

 coia of Guatemala., it has a bright yellow iris. Its alpine habitat — 

 the summit of the Volcan de Irazu — still further favors this view of its 

 afifinities.
