Simoprosopus, n.g. 
It has fallen to my lot to take exception more than once to 
Owen's identification of the skull named Zygomaturus by Macleay 
with the mandibles to which the former had given the generic name 
Nototherium. I cannot but think that sufficient evidence of the 
incorrectness of the disputed decision has already been adduced ; 
nevertheless, the support of the jaw mentioned below is far from 
unwelcome. Unfortunately, Macleay failed to observe the rule 
which strictly requires that a new name shall be announced in a 
publication addressed to the scientific world. This can hardly be 
said of the u Sydney Morning Herald," the sole repository of the 
name used by the author at its inception Under these circum- 
stances it becomes necessary that the genus should receive a new 
name, and for an emphatically flat-faced, snub-nosed creature the one 
above wiitten seems appropriate. 
SlMOPROSOBUS TRILOBUS MACL. 
Posterior moiety of a left mandible with the penultimate molar 
m.2 in place and remains of the last molar, m.3. The diameter of 
this jaw, drawn through the roots of m.3, is 85mm. in length, the 
index of a massiveness far exceeding any to be found in typical 
mandibles of Nototherium, yet the teeth are no larger than those of 
N. mitchelli ; they are about the same in length, but inferior in 
breadth. — No. 39. It was from the locality indicated by this number 
(Floraville) that the mandible brought under the notice of the Royal 
Society of Queensland (October, 1894) was procured. 
Hinder portion of a cranial vault, broken and imperfect. — No. 14. 
Fragment of a jaw, with remains of two molars. — No 10. 
Distal end of a femur, much waterworn. — No number. 
Large fragment from the middle of a long bone. — No. 17. This, 
however, may be from the Lesser Diprotodon, D. minor, Hux % 
Outer condyle of a femur. — No. 23.
