Tunicata, Polyzoa, Hydrozoa, Porifera, and Protozoa. — 

 A table case of Commercial Sponges arranged in geographical 

 series, with pictures and specimens illustrating the methods 

 of obtaining and preparing for market, has been completed. 

 The whole of the spirit collections have been examined and 

 replenished with spirit, and the type specimens placed in 

 pure fresh spirit. The spirit collection of Hydrozoa has been 

 re-arranged and expanded. The chief work of the year has^ 

 been the preliminary arrangement of the dry study collec- 

 tions of sponges and the making of catalogue lists of them. 

 The Bowerbank, Johnston, and Schmidt collections have 

 been arranged in the order of genera given by these authors 

 and in alphabetical order of species. Corrected nomenclature 

 according to recent research has been adopted. This work 

 is still in progress.
