Schlosser kept the specific name " minor " for a certain speci- 

 men of Andrews's and adopted a new name, '• andreirsi," for the 

 present species, which includes this t3'pe-specimen of M. minor. 

 Such a statement as Schlosser's is, of course, against the law 

 of priority : the name " minor " must be kept for the present 



1-4 1-3 



species. The length of P and of M of this type-specimen is 

 63 mm. and 74 mm. respectively. 



M. 9478; fragment of left mandibular ramus, bearing P — M.^ 



in situ, which are strongly worn. 



The mandibular ramus measures 52 mm. and 64 mm. in 

 depth at the anterior side of P and of M respectively. The 

 teeth measure as follows (in mm.) : —
