Bowerbank, J. S, a Monograph of the British Spongiadse, 
Vol. ii. London, Bay Society, 1866, pp. xx & 388. 
In this volume we have a synopsis of the British genera of 
Sponges, and descriptions of 193 species. One new genus, Oph- 
litaspongiay is described. In the synopsis of the genera, pp. 1-16, 
references to the illustrations in vol. i. are given, but in such a 
manner as to make it a matter of some difficulty to find out 
what species are figured.

Meeres, enthaltend die Yergleichung der Adriatisehen und 
Britischen Spongien- Gattungen. Leipzig, 1866, pp. 1-24, 
and one plate. 
The author brings the literature of the Sponges to the end of 
1865, criticises the genera proposed by Bowerbank in vol. i. of 
his work on British Sponges, and institutes a comparison be- 
tween the genera found in the Adriatic and on the British 
coasts.
