(Plate XIX.) 



The Rev. Deans Cowan last year forwarded to London a collec- 

 tion of birds, which arrived unfortunately in a bad condition, few 

 specimens having escaped the ravages of insects during the voyage. 

 Amongst the latter, I am happy to say, were a few Timeliine birds, 

 which have added considerably to our series in the British ]\ruseum ; 

 and not the least interesting is an example referable to a new genus, 

 which I propose to term 



Neomixis, gen. nov. 



Not distantly related to Muvornis, but easily distinguished by 

 the shape of the bill, which is conical and pointed, with a very sharp 

 culminal ridge, and scarcely any perceptible rictal bristles. 



In Madagascar it finds its nearest ally in Bernieria, like which 

 genus it has the culmen as long as the tarsus ; but the pointed 

 conical bill is very different from the long thin bill oi Bernieria. 



The type is 



Neomixis striatigula, sp. n. (Plate XIX.) 



Adult. General colour above olive-green, rather more yellowish 

 olive on the head, lower back, and rump, the hind neck somewhat 

 ashy : lesser and median wing-coverts like the back, the greater
