in South Africa suggested themselves, and while comparison shows these 
to agree fairly well in bill characters, wing formation, elongated tail and 
even feet nature they show completely booted tarsal covering. This 
strongly confirms the idea of convergence in the external features of these 
forms and if such be admitted why should not there be also convergence 
in internal characters. As evidence of this the Neozelanic Xenicus and 
Acantliisitta may be cited. These show somewhat similar internal features, 
and in the British Museum are placed in the same drawer, though no 
one would venture to claim direct relationship from a superficial criticism 
of the skins, while their habits are so dissimilar as to deny any alliance 
whatever, and Py craft’s researches in connection with Acanthisitta tend to 
prove that the haploophone syrinx cannot be regarded as having a very 
high value unless it is corroborated by other structural characters.
