This Mionectes is readily distinguished from its near ally M. striaticollis by its olive 

 head and throat, which in the other species are slate-coloured. The distribution of the 

 two forms is rather curious. M. striaticollis spreads from Bolivia and Peru to 

 Colombia, being probably found in Western Ecuador. It occurs in the trade collec- 

 tions of Bogota, and Salmon found it near Medellin in the Cauca valley of Colombia ; 

 this seems to be its most northern limit. M. olivaceus spreads over the whole of Costa 

 Rica and the State of Panama; it occurs again in Venezuela and in Eastern Ecuador. 



We have no records of the habits of M. olivaceus ; but M. striaticollis according to 

 Stolzmann * has a considerable range in the mountains of Peru, being found as high as 

 9300 feet above the sea at Cutervo. He adds that it frequents thick forests, keeping 

 amongst the low herbage, but sometimes ascending into the upper part of the higher 

 trees. Salmon obtained the eggs of M. striaticollis at Santa Elena in the Cauca valley ; 

 they were pure white.
