REPORT FOR THE YEAR 1901. 247 



obtained by Mr. Hedley at Palm and Gould Islands, Barrier Reef, 

 was a species of Gellius, commensal with an alga. 



By exchange with the West Australian Museum, Perth, twenty- 

 four specimens were obtained, half of which were new to our 

 collection. 



There are now exposed to public view three hundred mounted 

 specimens of Australian Sponges. 



A remarkably fine series of Corals, numbering fifty-nine speci- 

 mens and thirty-three species, was brought from Palm Island, 

 Barrier Reef, by Mr. Hedley, with equally good examples of 

 Heliopora coerulea, Pal., one with extended polyps, and an example 

 of the Giant Anemone ( Discosoma kentii, Had.). Our exhibition 

 cases now contain three hundred specimens of Australian Corals. 



Two rare Land Crabs (Geocarcinus lagostoma, M. Edw., and 

 Discoplax longipes, M, Edw.), were brought from Ocean or Pleas- 

 ant Island, by Messrs. F. Danvers Power and A. E. Stephen. 

 From Lord Howe Island, we received a Crab ( Lumbrios affinis, 

 M. Edw.), obtained by Mr. W. S. Thompson, previously known 

 only from Torres Straits, New Caledonia, and the Hawaiian 

 Islands. Another interesting addition to the fauna of this beau- 

 tiful Island, was a new Hermit Crab (Calcinus imperialis, 

 Whitl.),^'* inhabiting the shells of Tiirbo imperialis, Gmelin. The 

 presence of the much-dreaded Gribble (Limnoria lignorum, 

 Rathke), in wood taken from one of the jetties at Circular Quay, 

 and from a ferry steamer, was shown by Mr. Whitelegge^^ to be 

 an accomplished fact. 



A further valuable collection of Planarians, including thirty-one 

 specimens, representing fifteen species and varieties, seven of which 

 are types, was presented by Mr. Thomas Steel. 



During 1901, thirteen hundred and sixty-two specimens were 

 received by donation; thirty -four by exchange; twenty-four by 

 purchase; and seventy-four were collected. 



Ethnology. 

 (The Curator ; Mr. W. W. Thorpe, Mechanical Assistant). 



The collection of Australian and Polynesian Ethnology con- 

 tinues to increase, and the acquisitions were both interesting and 

 valuable. 



Dr. W. E. Roth continued to supply us with examples of 

 MoUusca, used by the North Queensland Aborigines as food, thus 

 adding fifty-five varieties to the excellent series already supplied 

 by the same gentleman. A complete list of the edible Mollusca
