Syrinx. 



The syrinx of Rhinochetus is displayed in the accompanying draw- 

 ing (fig. 1, p. 11). It will be seen that itis not specially distinctive, 

 and that it does not afford much help in deciding upon the affinities 

 of the bird. The lateral muscles spread out into a fan-like insertion 

 on to the third bronchial semiring ; the 2nd, Srd, and 4th bronchial 

 semirings are thicker than anj'^ of the preceding or succeeding 

 rings. The bronchidesmus is incomplete. The syrinx is not unlike 

 that of the Ardeidse, but is also like that of Ocydromus and other 

 Rail-like birds.
