48409. The imperfect palatal region of the cranium of an immature 

 {F^g.^ individual ; from the Pleistocene of County Phillip, New

 by Owen in the ' Proc. Zool. Soc' 1877, pi. xxxvii., and 

 pi. xxxviii. figs. 1-3. The four true molars are shown on 

 both sides, but while on the left side pm. 4 is in position, 

 on the right it is still in alveolo, pm- 3 and mm. 4 being in 

 use. Presented hy Rev. W. B. Clarke, 1877. 



M. 47. Fragment of the left maxiUa, showing the first three cheek- 

 teeth : from the Pleistocene of Queensland. 



Presented by G. F. Bennett, Esq., 1880. 



M. 47 a. Fragment of the right maxilla of an immature individual,

 from Queensland. Same history. 



40380. The imperfect left ramus of a mandible, with the four true

50063 a. Part of the left ramus of the mandible of a young indivi- 

 dual, probably belonging to this species ; from Queensland.

 Hcdmaturus ualahatus, auct. 



This species is smaller than any of the preceding ones, but appears 

 to be their nearest li^dng ally, having the fourth upper premolar 

 usually equal in length to one and a half times that of the first true 

 molar, and the upper true molar of a similar structure; the third 

 upper incisor is vertically grooved, and somewhat larger than the first; 

 there are large palatal vacuities. The lower true molars are of a 

 short and simple type, like those of the preceding extinct forms. 

 The length of the upper series of cheek-teeth averages 0,039, and 

 that of the lower jaw 0,0395.
