* We may account for the great variation in this very natural group, by 
supposing it is that which connects Sylvza to Malurus. 
+ This seems the tropical representation of Regulus : it is at once known 
by its disproportionately long toes and claws. It is the Reg. Byronensis 
of Griff. Cav. 
{ Although this extraordinary form has all the aspect of an Anthus, I 
cannot but think that this is merely its disguise, and that its natural affini- 
ties are in this group. It has a strong resemblance to Acanthiza, and more 
to Orthotomus, in its tail and wings. I have therefore placed it as the 
representation of Anthus in this group, until its affinities are better under-
