REPORT ON THE FORAMINIFERA.

happily unnecessary, the genus Haliphysema has been assigned by general consent to the 
arenaceous Bhizopoda. 
The fact that no specimens pertaining to the genus have been found in the collections 
to which the present Beport immediately refers, together with the completeness with 
which its structure and affinities have already been worked out, render any extended 
account of it superfluous. At the same time it appears desirable that the two recognised 
species should be figured amongst the arenaceous forms to which they are most nearly 
allied, and that their characters should be sufficiently described to ensure their easy 
identification. For particulars as to their minute structure and morphology the student 
will naturally consult the writings of Carter, Saville Kent, Bay Lankester, and Moebius, 
in which the subject is treated with an amount of detail that would be out of place here, 
and with graphic illustrations on a scale that would be equally unfitting. Free use has 
been made of the memoirs alluded to in the brief descriptions which follow, as well as of 
the recently published supplementary volume of Bowerbank’s “ British Spongiadse,” in 
which the Bev. A. M. Norman has summarised the whole matter, and has likewise 
furnished a complete synonymy of the members of the group. 
For the figured specimens I am indebted to my friends H. J. Carter, F.B.S., and the 
Bev. A. M. Norman.
