MICEOOEECULUS.— TJEOPSILA. 77 



subsequently not unfrequently met with in the same districts, and often heard in the 

 forest country lying between Cahabon and San Luis. The song of M. philomela is 

 remarkable for its sweetness and for the high notes of which it is composed. It is clear 

 and melodious, without having much variation. The bird appeared well known to the 

 native hunters under the name of " Kuisenor " (or Nightingale), a title its vocal 

 powers have gained for it. We only found it in the undergrowth of the virgin forest, 

 where, but for its song, it would be a most difficult bird to see, owing to its small size 

 and the sombre tints of its plumage. 



Some diversity of colour is observable in different specimens of this bird, the throat 

 of some being much lighter-coloured and the crescent-shaped marks of the under surface 

 paler. These examples may have been young birds.

This Wren was a discovery of M'Leannan's, who shot a female specimen on the 

 ground in the jungle, and sent it to Mr. Lawrence ^. That naturaUst at first referred 

 it with doubt to the Guiana M. bambla \ but afterwards to the Guatemalan M. philo- 

 mela^. Prof. Baird, on examining this specimen and comparing it with one of M. 

 jahilom^la, considered it to be a more adult specimen of the last-named species ^ ; and 

 it was only on the receipt of two additional examples that Salvin separated the species 

 under the name of M. luscinia *. The two are doubtless nearly allied ; but the differ- 

 ences seem constant and sufficiently recognizable. No accounts of the habits of this 

 bird have yet reached us. 



Another near ally of M. luscinia is M. albigularis, Scl., from the valley of the Napo 

 in Ecuador ; but in that species the throat is of a purer white, the legs yellowish instead 

 of dark brown, and it is smaller in all its dimensions.
