In Physiology, Masterman (31) describes the nutritive and excretory 
processes in Porifera , and points out their strong resemblance to the 
corresponding processes in the Choanoflagellata. Letellier (28, 29), and 
Topsent (44) discuss the boring action of Cliona. 
Zoologists may congratulate themselves that no new classification of 
sponges has been proposed this year. Topsent (46), in his monograph, 
adopts, with trifling alterations, Sollas’s classification of the Tetractinellida. 
Under this head we may mention Topsent’s (45) useful revision of 
Bowerbank’s nomenclature, drawn up on similar lines to that proposed 
by Hanitseh in the previous year. 
Papers ou the geographical distribution of Marine Sponges are Top- 
sent’s monograph (46) of French Tetractinellida , Dendy’s Catalogue 
(7) of Non-Calcareous Sponges from Port Phillips Heads, and Weltner’s 
report (50) on the Sponges from the Eastern and South-eastern North 
Sea. In Freshwater Sponges, Weltner’s account (51) of the distri- 
bution of all known species of the globe will be of the greatest value. 
Hanitsch (16) describes the freshwater Sponges of Ireland, and 
announces the occurrence of two or three American forms in that 
country. Petr’s account (37) of European Spongillidce would no doubt 
have been much more useful, if it had not been written entirely in 
Bohemian. 
In Fossil Sponges, we are glad to have now before us Part III of 
IIinde’s Monograph (19), treating of the Spouges of the Jurassic Strata 
of Britain, which are chiefly calcareous. Rauff (39) has continued his 
u Palmospongiologie,” but the Recorder is sorry not to have been able to 
see the work.
