3 specimens, 2 cT, i 9 , which are decidedly smaller and paler than 

 those I have examined from British Guiana and Colombia. Judging 

 from the material before me, the Margaritan birds are separable at 

 least subspecifically, but from lack of a satisfactory series for com- 

 parison, I refer it provisionally to this species. 



Glaucidium phalsenoides (Daudin). 



Recorded by Captain Robinson and Mr. Clark. It was not taken 

 or observed by Mr. Ferry. 



Aluco sp. ? 



Mr. Ferry saw what he believed to be a species of Aluco in a cave 

 in the mountain above El Valle, but the bird was not taken. 



Family Psittacicla*.
