ISOPODA ABERBANTIA. 
TANAlDiE. 
In the Record for 1864 (p. 264 ) we drew attention to a com- 
munication by Dr. Eritz Mlillcr (Archiv fiir Naturg. 1864 ), in 
which he asserted that the cephalon in the genus Tanais is de- 
veloped upon the type of the carapace of the Decapoda. To this 
conclusion we demurred, because his suggestion rested upon in- 
duction only. But it would not be just to that distinguished 
carcinologist if we did not take the earliest opportunity pos- 
sible of withdrawing the objections we then made to his hypo- 
thesis, and state that, very recently, we have been enabled by 
actual observation to confirm his opinion. In some living 
specimens which we very recently procured we have seen not 
only the current of water to which Dr. E. Muller alludes, but 
the branchiae existing in a position that induced the circulation 
of that current. They consist of a single branch on each side, 
attached to tlie coxa3 of the large pair of claws (1st pair of giia- 
thopoda), and lie diagonally forwards in a chamber formed by 
the lateral walls of the cephalon. The branchiae are in constant 
play, waving to and fro. (We hope shortly in some other place 
to describe the structure and anatomy of these little creatures 
more fully.)
