emale. Prof. R. Owen, upon receiving the casts of the Harpagornis bones fromGlenmark, has confirmed my views, that they belonged to a gigantic extinctharrier, and a study of the mandible in question has strengthened to mymind this hypothesis considerably. However, before offering a descriptionof these bones under review, I wish to point out that we have proof that twospecimens of H. assimilis were imbedded in the Hamilton peat beds. If we admit Mr. Booths theory about the formation of these deposits,viz., that they were formed in lagoons, obtaining their supply of water fromsprings only, it is difficult to understand how the bones of the two birds couldhave been brought there, unless we admit that by feeding upon the carcassesof those moas perishing in the springs from some cause or other, they were * m Trans.

This mode may also account for the extreme rarity of the remains ofHarpagornis, which I am sure flourished in considerable numbers during theMoa Age. Mandible of Harpagornis assimilis. Total length measured from point of symphysis along the ramus toposterior end of articular process 4*75 inches, greatest distance betweenarticular processes, measured from the outward sides, 3 inches. From a comparison of the general form of this mandible with that ofthe New Zealand harrier (Circus assimilis) it will be seen that it is some-what narrower in proportion than that of the latter. In this respect itresembles the mandible of the condor (Sarcorhamphus gryphus) and griffinvulture (Gyps fulvus). However, as several others of the vultures have abroad mandible, this character is

Orel Haastův

Orel Haastův je vyhynulý druh orla z Nového Zélandu, který představoval vůbec největšího orla všech dob. Podle odhadů samice vážily 14 kg, možná až 17,8 kg, zatímco menší samci měli kolem 10 kg. Rozpětí křídel dosahovalo asi 2,6 m, u největších jedinců snad až ke 3 m. Orel Haastův se vyskytoval pouze na Jižním a Stewartově ostrově, na Severním ostrově doložen nebyl. Veškeré znalosti o orlu Haastově jsou založeny na nálezech kosterních pozůstatků, v některých směrech poskytuje vodítko i maorská ústní tradice. .. pokračovat ve čtení
