On the Foetal Membranes of Chelonia. 
By K. Mrrsuxvuri, Ph. D. 
(Preliminary Communication.) 
With 5 figures and 7 diagrams. 
Whilst collecting embryos of Chelonia, I became aware of the 
fact that there are some very notable features presented by the foetal 
membranes of these animals which, so far as I am aware, have hitherto 
been entirely overlooked. These features appeared to me so remark- 
able and interesting that I have thought it worth while to investigate 
the whole history of these membranes in this group. The investi- 
gation is now brought to a close and the results with full details will 
be published in the course of the present summer in the College Jour- 
nal of Science, Imperial University, Tokyo, Japan. Meanwhile I have 
thought it best to give the following brief SUNY of the results to 
reach a wider circle of readers. 
The species which I have investigated are Clemmys (or Emys) 
japonica Gray and Trionyx japonicus SCHLEGEL.
