Boricha hryantoe was described by Mr. Lawrence from specimens sent by Julian 

 Carmiol from Costa Rica to tbe United States National Museum. The precise loca- 

 lities where these specimens were procured was not stated in the first instance ; but in 

 his List of Costa-Rica birds Mr. Lawrence gives Dota and Las Cruces de Candelaria 

 as places where this bird is found. In parts of the State of Panama it appears to be a 

 very common bird, as our collector Arce sent us a large series of specimens, mostly 

 obtained at Castillo. 



Mr. Lawrence compared D. hryantoe with B. evelynoe of the Bahama Islands, and no 

 doubt the two birds have some characters, such as the colour of the apices of the lateral 

 rectrices of the females, in common. But B. bryantoe is the only species of the genus 

 which has all the outer rectrices edged on the inner v^ebs with rufous— a small but 

 significant character. 



j". Cauda elongata, furcata, rectricibus lateralibus transfasdatis. 



TILMATURA.

The single species constituting this genus is a very peculiar bird as regards the 

 coloration of the outer rectrices of the tail ; these are conspicuously tipped and banded 

 with white in a way not found in any other Humming-Bird. The outermost rectrices 

 are peculiarly shaped, being reduced in width towards the end and then slightly 

 expanded to form an incipient spatula. In other structural characters Tilmatura 

 seems to come next to Boricha. 



The range of the genus extends over Southern Mexico and Guatemala to Northern 

 Nicaragua.
