Grallaria, VieilL 



Marginata, Pr. Max. 

 The only difference in form between this bird and the foregoing is that the pelvis is 

 broader; it still, however, has the same linear form of ischiadic foramen, and the pro- 

 cess at the junction of the rami of the os furcatum points backwards. 



ClNCLORAMPHCJS, Gould. 



Cruralis, Vig. $ Horsf. 

 This bird has been classed with Malurus, but the skeleton is precisely that of 

 Grallaria, with the exception of the ischiadic foramen being rather more open.

FoRMICIVORA, SlV, 



Grisea, Stride 

 Cranium with the vertex very convex, orbital septum nearly obliterated. Palatine 

 bones with the lateral spines pointing backwards, and very long, 

 Sternum very broad in proportion to its length. 

 Pelvis broad, the ischiadic foramen very large. 

 Humerus as long as ulna. 

 Leg-bones long. 



1 have great doubts as to whether or not this is the right family for this bird.
