 of antiquity impressed on their organisation, the mound-building 

 birds vie with the Monotremes in asserting their hold upon the past. 

 We should therefore be surprised were we not, sooner or later, to 

 discover in the deposits which contain remains of the Monotremes 

 a trace of those remarkable birds Megapodius, Talegallus, 

 Leipoa, or of some other near akin to them. Part of a single 

 limb-bone is but a trace ; at the same time if its characters 

 are such as to persuade one to place considerable reliance on any 

 decision to which it may lead, it is justifiable to bring forward its

 of the metacarp of the left manus wanting the lesser limb of that 

 compound bone — this limb having been broken off at its confluence 

 with the medial limb. In the notes following, this lesser element,
