The i)reseiit notes are based on the reinaimler of the collection from 

 which the new sjjecies were described in a former i)a])er in these Pro- 

 ceeilin^^s,* and is really a continnation of that paper. 1 have, however, 

 added sonie few notes from observations made on birds in the Costa 

 Rica National ]\[nseum since my retnrn. 



I would here exi)res8 my thanks to the authorities of the Smithso- 

 nian Institution for the opportunity of examining- their bird collection 

 in t'omparison with Costa Uica examples, and also acknowledge my 

 indebtedness to Mr. Kidgway and Dr. Stejneger for much kindly 

 assistance. 



Cathaius melpomene. 



In a series of twenty-seven adult birds of this species, fifteen from

 it) asfumosHs, I believe is me.ricanus, having the wings and tail "dusky 

 brown with bistre brown edgings," and many feathers of the back with 

 a decided brownish cast.

Above brownish olive, ln>ad slightly darker, feathers bhu-Uisli basally, 

 and having narrow ochraceous shaft-streaks. Scapulars with sub- 

 terminal elliptical ochraceous shaft-spots, feathers, narrowly tipj^ed 

 with blackish. Greater coverts <lusky brownish with bistre edges, 

 somewhat brighter than on the quills. Many of the feathers of the 

 back with a decided N'andyke-brown shading. Tips of upper tail- 

 coverts Vandyke-brownish. Tail like the wing. Below, feathers of the
