Schmidt, in this appendix to bis great work on the Sponges 
of the Adriatic, not only adds several species to the fauna, but 
also gives an introductory chapter on the histology of the 
Sponges, with some remarks on their position among the 
Protozoa.

The author describes an enormous number of new species 
(? varieties), which we refrain from quoting, in the belief that 
this paper must be consulted to be understood.

Prof. Clark does not agree with Kolliker that Actinophrys 
is a homomorphous mass with vacuoles, but thinks that the so- 
called vacuoles of the outer and inner layers are true cells, 
with a distinct wall about them. Appended to this paper are 
some interesting remarks by Prof. Clark on cnidee.
