512 Mr. F. E. Beddard — Omitholoyical Notes. 



make out whether the difference in the tongues of the two 

 Japanese birds were correlated with differences of sex. The 

 birds had been in spirit for a good many years, and the 

 viscera were too much softened to permit of a determination 

 of the sex. 



It is evident, therefore, that the simple structure of the 

 tongue described by Dr. Gadow in Zosterops lateralis does 

 not characterize the genus; we have in Zosterops simplex 

 and in Zosterops japonica^ a transition towards the more 

 complicated form of tongue of the Meliphaginae, both in the 

 frayed-out extremity and in the folded margins. Dr. Gadow 

 states that Zosterops is not a Honey-sucker ; nevertheless 

 the form of the tongue is such as to suggest that Zosterops 

 simplex and Z.japonica may belong to that group. 



II. On the Convoluted Trachea of Manucodia comrii. 



Some time ago Mr. Sclater kindly put into my hands a 

 body of Manucodia comrii, showing the convoluted trachea 

 in position. 



That the trachea of this genus has a subcutaneous convo- 

 lution lying upon the pectoral muscles has been known for 

 a long time ; but up to the present the trachea of this 

 particular species {Manucodia comrii) has not, so far as I am 

 aware, been described or figured. I am therefore greatly 

 indebted to Mr. Sclater for enabling me to examine the 

 structure of the windpipe in this species. 



In the ' Proceedings ' of the Zoological Society of London 

 for 1882 1, my predecessor, the late Mr. W. A. Forbes, has 

 given a very useful summary of what was then known with 

 regard to the convoluted trachea of birds, devoting some 

 space to a consideration of Manucodia and of the allied genus 

 Phony gama. 



It appears from tliis paper that in Manucodia the adult 



* This is the only species occurring in Japan, according to Seebohm 

 (' Birds of Japan,' p. 68).
