With the exception of rnjipectus, this is the rarest of the genus 

 Formicarius in Costa Rica. Up to 1893 all Costa Rican and Chiriqui 

 specimens were referred to as F. analis, and there may be some con- 

 fusion in the records, some specimens of F. umbrosus (then not 

 described) probably being also referred to analis, since the ranges of 

 the two birds overlap along the foot-hills of the Caribbean. 



I was never able to secure specimens of this rare species, so know 

 nothing about the bird in life. However, from what I have been able 

 to learn I should say that the range of this species covers the foothill 

 region of the Caribbean slope from about 1,200 up to 2,500 feet, and 

 that it is undoubtedly found in the dark humid forests peculiar to the 

 foot-hill region, like some other species of the Formicariidce.
