DEPARTMENT OF ZOOLOGY. 141 



illustrating the destruction of submarine woodwork on the 

 coast of Natal by SijhcBroma terebrans have been mounted and 

 placed in the Gallery. 



Of the Norman collection, received in 1911, 18,718 specimens 

 have been registered during bhe year ; and the tubes, as far 

 as registered, have been sealed with paraffin wax to delay the 

 evaporation of the spirit. The Koch collection of Wood-lice, 

 contained in 259 tubes, was received during the year, but it has 

 not yet been possible to begin its arrangement or registration. 

 The Budde-Lund collection, received in 1912, also awaits label- 

 ling and registration. The remaining accessions have been 

 registered and incorporated as far as the congested state of the 

 Crustacea Room would allow. 



ECHINODERMA. 



The exhibited collection of Stalked Crinoids has been re- 

 spirited and the labels and covers restored. The congestion of 

 the study series in the Spirit Building is becoming more acute. 

 Most of the specimens obtained during the year have been 

 determined, and all have been incorporated. Owing to the 

 destruction of valuable property in various places, the rare 

 Holopus has been withdrawn from the Gallery. 



Worms. 



The MS. list of the Chaetognatha has been completed. 



The appointment of a new Assistant has given the opportu- 

 nity of passing over to him the care of the collections repre- 

 senting some of the groups of " worms." He has devoted 

 special attention to the Nemathelminthes, but other groups, 

 and particularly Platyhelminthes and Nemertinea, will probably 

 be taken over by him in due course. 



With the help of Mr. W. A. Harding for Leeches, and of 

 Dr. Cognetti di Martiis for Oligochaeta, nearly all the Avorms 

 obtained during the year have been determined, and they have 

 all been incorporated. 



Some improvements have been made in the exhibited series 

 of parasitic worms, and numerous bottles in the study-series 

 have been re-spirited, while the systematic arrangement of the 

 microscopic slides has been continued. 



POLYZOA. 



The arranging and registering of 373 spiiit specimens of the 

 Norman collection of Polyzoa have been completed. 



The conservation of the slide-collection of Polyzoa has been 

 begun, many of the preparations preserved in fluid having been 

 stained where necessary and remounted in glycerine or Canada 

 Balsam. 



Anthozoa. 

 The MS. Catalogue of the Pennatulida has been completed. 

 Nearly all the specimens of the Anthozoa added during the
