The Plovers and the Rails do not stand far apart in Nature, and the two types are for 
ever blending to form secondary types, e. g. Parra, Botaurus, Grus, Psophia ; but the 
Plover is at once more nearly related both to the Ostrich and to the Lizard than the 
Rail, and yet it isa more intelligent bird. 
The “‘ Struthionide ” are hemmed in on all sides, except the Mammalian, with the 
genera that have taken up so much of our attention in the present paper ; yet are they 
the most unconformable of all the living feathered tribes, and I much question whether 
the Archeopteryz itself did not agree better with ordinary birds, it having no such con- 
tiguity to the Mammals as we see in the Ostrich-tribe. 
The relationships of the Talegalla may be faintly shown by the appended scheme. 
Gallus. 
Crax. 
Brachypteryz. Talegalla. Rhinochetus. 
Palamedea. 
Those of Hemipodius by the next. 
Coturniz. 
Dendrortyx. 
Didunculus. Hemipodius. Charadrius. 
Tinamus. 
The affinities of Syrrhaptes appear to me to be as follows, viz. :— 
Gallus. 
Lagopus. 
Chameopelia. Pterocles. 
Hemipodius. Syrrhaptes. Charadrius. 
Tinamus.
