218 ZOOLOGICAL RESEARCHES 



streaks on chest and interscapularies , which streaks are 

 present in G. calvus , but wanting in G. peli, it is almost 

 impossible to distinguish immature birds of both species , 

 as the mentioned characters are wanting in both of them 

 entirely. 



These birds live together in little colonies of 4 to 10 

 pairs and make their nest-holes , like the woodpeckers , in 

 dead tree-trunks , sometimes three to six pairs in the same 

 trunk. They are as much as I could observe, not by far 

 as sluggish as Dr. Reichenow describes them. I met with 

 them several times in the forest, and always they were 

 very noisy and desirous of fighting, moving quickly from 

 branch to branch till they found a fruit-tree, where the 

 noise became still greater than beforehand. They feed upon 

 several small kinds of wild fruits. 



Iris in both sexes grayish brown , bill dirty flesh-color , 

 feet gray, bare skin on the head grayish black. 



Track yphonus goffini.

Hab. Liberia and Gold Coast. 



Collected near Sofore Place. 



The Liberian specimens are not at all different from 

 those from the Gold Coast. They are found in pairs in 

 the brushwood of old farms , where , at short intervals , 

 their deep call »hoop" can be beared. The huntsman , once 

 acquainted with this peculiar note, can approach the birds 

 easily enough, as they are not shy and look very calmly 

 at the barrel directed upon them. 



Iris red, bill orange-yellow, bare skin round the eye 

 bluish black, feet grayish brown.
