ANATOMY OF THE KAGU.

to me, as they have seemed to Fiirbringer, to indicate a certain 

 degree of relationship in this direction. The muscular anatomy as 

 a whole is decidedly Crane-like, as will be seen by the following table, 

 which shows some of the resemblances and differences between the 

 Cranes, Herons, and Rhinochetus. 



At the same time the absence (?) of a biceps sHp to the patagium 

 and the presence of a peculiar additional biceps muscle are peculiar- 

 ities which mark off Rhinochetus from other Crane-like birds. 



The syrinx is not specially like that of the Herons ; it is perhaps 

 more like that of Cariama than other types, but is also like many 

 other Gralline birds. With regard to the special affinities between 

 Rhinochetus and Eurypyga they are evidently very close ; but I pro- 

 pose to defer the consideration of these until I have an opportunity 

 of adding to my notes upon Eurypyga. 



1 I could not find the biceps slip in my specimen, but as I have since found a 

 MS. note by G^arrod affirming its presence, I have possibly failed to see it.
