NOTE ON MYRIODON AND PL A TYCRANIUM. 
By Dr. E. C. N. van Hoepen, m.i. 
Dr. Broom kindly informed me some time ago that the name Myriodon 
was already given to a fish in 1847 and is not available for the Senekal 
Stegocephalian. The genus to which this fossil belongs must therefore 
be renamed and 1 propose the name : TJranocentrodon .* The type species 
is : TJranocentrodon senekalensis v. Hoepen sp. 
In verifying the above I found that the name Platy cranium , which 
I proposed some time ago for a small Cynodont, is preoccupied twice in 
the form of Plcttycranius. I therefore wish to change the former into 
Platy craniellus | with the type species Platy craniellus elegans v. Hoepen 
sp. 
* Grr. ovpxvog = palate, xevrpov = point, prickle, oSou$. = tooth, 
| Gr. 7rXdTvq = broad, a pav'iov = skull.
