I.— Observations upon Professor Ernst Haeckel’s Group of the 
“ Physemarta,”’ and on the Affinity of the Sponges. By W. 
SAVILLE Kent, F.L.S., F.Z.8., &e. 
Iv was scarcely to be expected that Mr. Carter would quietly 
surrender into Prof. Ernst Haeckel’s hands, for the further 
exposition of his celebrated ‘“Gastreea” theory, that imterest- 
ing organism, Sguamulina scopula, which he (Mr. Carter) a 
few years since pronounced, and still holds, to be a Forami- 
nifer. The brusque and, it must be admitted, somewhat dis- 
courteous manner in which the learned professor disposes of 
Mr. Carter’s arguments in support of the view which he 
adopts has also naturally led to the protest that appears in 
the last October number of the ‘ Annals.’ In this protest, 
however, Mr. Carter does not appear to have made the most 
of his own position, nor, indeed, to have clearly defined the 
one maintained by Prof. Haeckel. 
Though unable at the present moment to refer to the article 
which has so greatly perturbed Mr. Carter’s equanimity, I 
was fortunate enough to obtain in May of this present year, 
and still have by me, a copy of Prof. Haeckel’s ‘ Biologischen 
Studien,’ zweites Heft, 1877, containing a chapter entirely 
devoted to the consideration of the so-called Squamulina 
scopula and its supposed allies. It is upon these forms col- 
lectively that the author bestows the title of the Physemaria ;
