 commissure is but -slightly apparent.

Mr. Lawrence having kindly sent me his unique example of this 

 species for examination, I have come to the conclusion that it is a 

 young male of a species of Lanio, allied to L. versicolor, and re- 

 markable for its small size.

In the smaller and weaker Taclu/phoni the dental tooth is hardlv 

 apparent, but the general conformation is that of Lanio. The genus 

 consists of twelve or thirteen species, which do not range higher in 

 Central America than Costa Kica, but extend southwards to Para- 

 guay and Bolivia. 



The nesting of T. melaleucus has been well described by Euler
