Ols. The skull, without a lower jaw attached, from King’s Creek, presented to 
the Australian Museum by Mr. P. N. Isaac, and upon which Mr. Macleay established 
his genus Zygomaturus, Prof. Owen says, belongs to the same species as t e ouer jaw 
originally described by him from the same locality as Nototherium Mitohelh. ihe 
latter is now in the British Museum, and was purchased after being sent to London by

Obs The specific difference of H. inerme from the other two species of the genus 
is shown in the relative position of the symphysis to the fully-developed molar series. 
The name refers to the absence of incisor tusks. 
Mr. Lydekker includes both this species and N. victonm, Owen, as synonyms ot

” Obs A mandibular fragment and a left adult mandible have been separated by 
Mr De Ws at representing another species of mtotheriim. It is distinguished from 
JSf. Mitchelli Owen, “by the size and structure of the preinolar and position of the 
inlet of the dental canal” ; from H. inermis, Owen, “ by the develoiment of the tusks 
and consequent retrocession of the symphysial curve” ; and from D. Fiirfoiv® Owen 
“by the position of the inlet of the dental canal and by the gradual enlargement ot
