PorccUio dilatatm (Brndt.). Professor Wagner has, in the November 
number of the Annales des Sc. Nat. for 1865, vol. iv. p. 37, published some 
observations on the circulatory and respiratory systems as observ^ed by him 
in this species. Having adopted the method that was first shown to be prac- 
ticable by M. Emile Blanchard, and which has since been successfully pur- 
sued by M. Kowalewsky on Idotea, he injected a mixture of glycerine 
and water coloured with carmine into the arterial system, through the 
heart, and by so doing was enabled to confirm the conclusions of M. Kowa- 
lewsky that there exists a well-developed arterial system in the Isopoda. 
The greatest amount of arterial development, as might have been anticipated, 
is to be found about the cephalic, branchial, and generative organs, as the 
author has illustrated by four diagrammatical figures. 
In writing of the branchial organs Professor Wagner says that the pleon 
(partie abdominale) of the Isopoda does not correspond with the pleon of the 
Hecapoda, but with the lateral part or branchial region of the pereion. An 
expression of this kind is only intended to convey that the office of respira- 
tion is carried on in different orders of Crustacea by parts that are homo- 
logically distinct. We might therefore reasonably suppose that, in order to
