AT the Evening Meeting of this Society, held on the 17th of 
November, 1858, a paper by Mr. Stow “On some Fossils from South 
Africa” was read. In the course of the discussion which followed, 
my opinion as to the nature of one of those fossils was asked. With 
so much reserve as was due to the cursory character of my examina- 
tion of the remains, I expressed my conviction that the organism 
in question was the skull of a Labyrinthodont Amphibian, and 
briefly stated the grounds upon which I based that conclusion. The 
Chairman of the Meeting then called upon me to undertake a 
thorough investigation of the matter; and I now report the results 
of my inquiries in the first of the following papers, in which I 
have embodied, incidentally, the description of an allied Australian 
Amphibian. 
1. Ox Micropholis Stowii ava Bothriceps Australis. 
Micropholis Stowi.—The skull in question is 12 inch long, and 
has, when viewed from above, a parabo! icoutline (P]. NXI. [Plate 7] 
fig. 1), or it might be compared to the half of a long ellipse, half of 
the longer diameter of which is to its shorter diameter as 13 to 10. 
The bony plates which formed the roof of the skull (fig. 1) have 
entirely disappeared, as have those which constituted the greater 
part of its right lateral parietes; but on the left side (fig. 2), the 
lateral walls are in a tolerably good state of preservation. 
The matrix has split in such a manner that that portion of it
