 b". Bill with a slight notch ; culmen 

 very long and equal to the tarsus. 4. 

 Rictal bristles so feebly developed that

 second joint of outer toe free. 

 «*. Tarsus not twice the length of 



outer toe and claw 



b*. Tarsus twice the length of the 

 outer toe and claw. 

 a'\ Wings very long, falling 

 short of the tail by less 

 than the length of the cul- 

 men ; bill laterally incurved 

 towards the tip, the edges 

 of the bill, when viewed 

 from above, curving in- 

 wards gradually about the

* Mr. Cory's genus 12. Lic/ia comes in somewhere in the neighbourhood of 

 Geothlypis, with which genus he compares it. The wing is, however, stated to 

 be equal to the tail in length, and therefore it would belong to the previous 

 Beotion ; but without seeing a spocimen I am unable to locate it more exactly.
