DEPARTMENT OF ZOOLOGY. 93 



The crowded condition o£ the cupboards in the Spirit Building 

 now makes it practically impossible to deal satisfactorily with the 

 arrangement of additions to the spirit collections. 



POLYZOA. 



The exhibited series of Polyzoa has been removed from the 

 Shell Gallery to the Coral Gallery, and re-arrangement of the 

 specimens is being carried out. 



Hydrozoa. 



Several important collections have been labelled, registered, and 

 incorporated. The bottles of the Norman collection of Hydroida 

 have been replenished with spirit. Upwards of 600 microscopic 

 slides of Hydroida have been prepared, to facilitate the examination 

 of specimens. A scheme has been designed and adopted for the 

 better preservation of the dried Hydroida. The large accumulations 

 of unnamed Hydroida have been worked at, and numbers of very 

 interesting species, which were hitherto not known to be represented 

 in the collections, have been brought to light. 



The sorting and determination of the Hydroida of the British 

 Antarctic ("Terra Nova") Expedition, 1910, have been carried on. 



PORIFERA. 



The acquisition and exhibition of a large and very fine cup- 

 shaped example of Spongia op.cmalis, var. Lamella, led to the re- 

 arrangement of the exhibited series of Horny Sponges. 



The restoration of type collections, important specimens and 

 exhibited specimens, which had been removed to places of safety 

 during the war, was completed at the beginning of the year.
