Supra olivaeeo-brunneus, capite toto cum collo griseis, pileo paulo obscuriore, alis extus et Cauda cinnamomeis ; 

 subtus griseus, guttuie pallidiore, ventre medio et crisso albis; rostro et pedibus aurantiacis. Long. 

 tota 6, alse 3'5, caudse 2-6, rostri a rictu 0*85, tarsi 1-25. (Descr. maris ex Santa Pe in Statu Panamensi,

Hob. Panama, Volcan de Chiriqui, Santa F^, Chitra, Calovevora, Calobre {Arce ^ ^ ^). 



This species appears to be restricted in its range to the mountainous parts of th« 

 State of Panama, being found from the Volcano of Chiriqui to Santa F^ and Calobre. 

 Further eastward it has not yet been met with, as none of the large collections made 

 on the line of the Panama Eailway have contained examples. The grey head and nearly 

 uniform ashy under surface are distinguishing characteristics of this species. 



7. Catharus gracilirostris. (Tab. I. fig. 1.)

Supra oleagineo-brunneus, capite toto obscure cinereo ; subtus cinereus, pectore dorso concolori ; rostro nigro, 

 pedibus corylinis. Long, tota 5-5, alae 3-0, caudse 2-7, rostri a rictu 0-8, tarsi 2-2. (Descr. exempL typ. 

 ex Volcan de Cartago, Costa Eica. Mus. nostr.) 



Hab. Costa Eica, Volcan de Cartago {Arce'^, Rogers), San Mateo (/. Cooper^). 



Originally described from two specimens obtained for us by Arce in the Volcan de 

 Cartago. Even in Costa Eica, the only country where it has been found as yet, the 

 species must be considered rare, few other specimens having come under our notice. 

 M. Boucard, during his recent journey to that country, obtained but two examples, both 

 from the Volcan de Cartago, from which locality Eogers also procured us a specimen. 

 This last is a young bird, the remains of the spotted plumage showing on the under surface. 



The black slender bill, grey head, and olive chest serve to distinguish this species at 

 a glance from all its congeners.
