likely belong to the cerebellum. 
At the bafis of this kind of unformed cranium , 
forwards, was an opening leading to a fmall brown 
hydatide, fituated on the right fde, under a bone 
which had the appearance of a portion of the maxilla , 
which led towards a fort of mouth, fcarce formed, 
and clofea it is reprefented at the letter ( a ) of the 
fir ft fi gure. There was nothing on the other fide, no 
appearance of a mouth, nor any thing that feemed 
the leaft like it. 
I took this hydatide for an unformed jugular bag, 
or true caecum ; in the adjoining bone I found a kind 
of right ear. 
The fore part of this fame fuperior furface of the 
cranium was flat, but a little hollowed, like the 
upper furface of the larynx ; in the middle was a 
confiderable ridge, and on its anterior part appeared 
a prominence : thus this bone, which fhould have 
been fimilar to the two parietals , did not referable 
them at all. 
Underneath this prominence, the bone took a 
perpendicular turn, making a fharp angle with the 
upper furface, and forming a cavity in its defcent, 
which terminated in a projection forwards it was 
on the right fide of this projection where the fup- 
pofed right branch of the maxilla was attached ; 
within that branch appeared the trace of the jugular 
above-mentioned, and very diftinCtly the nerve of 
the eighth pair. 
In the breaft, or rather under the ribs, were nei-
