^ Three specimens. 



" An adult female of a Tachyphonus from the Segovia River, Honduras, in the U. S. 

 National Museum collection (No. 112099, Segovia River, June 18, 1887, C. H. Town- 

 send), is very similar in coloration to the adult female of T. nitidissimus, but has the 

 throat entirely yellow, like rest of under parts, and the sides of head yellowish olive- 

 green. It may represent individual variation in this species or, possibly, a distinct 

 form. Its measurements are as follows: Length (skin), 132.1; wing, 60.2; tail, 55.1; 

 exposed culmen, 12.2; depth of bill at base, 6.4; tarsus, 18; middle toe, 10.2. 



'According to Jose C. Zeledon, collector of the type specimen. ■
