Adult 9 (No. 102,811, Cozuinel, Jauuary 22): Similar to the young 

 male, as described above, but without auy of the cinnamon alon<>- sides 

 of throat, etc., the bhick of the middle line of the throat extending 

 anteriorly to the point of the chin, and white of cheeks reaching almost 

 to the lower eye-lid. Wing, 2.60 ; tail, l.GO • bill from frontal feathers,. 

 1.05. 



The examination of a larger series of this bird and L. prevosti than 

 were compared when it was first described shows that it is not so dis- 

 tinct as at first seemed to be the case. The characters given in the 

 original diagnosis will, in the main, be found to hold good, and the form 

 may be considered as a fairly well defined local race of L. prevosti.
