772 Zoology. 



In 1886, 35 specimens and preparations of Australian 

 Medusa. Purchased from Dr. R. von Lendenfeld. 



In 1889, there was added the collection of Siphonophora, col- 

 lected by the " Challenger" and described by Prof. E. Haeckel. 

 The 24 specimens of this collection include the remarkable deep- 

 sea forms belonging to the group Auroneetse, " one of the most 

 splendid discoveries of the ' Challenger'" (Haeckel, " Challenger '' 

 Siphonophora, p. 305). 



C. Hydrocorallisle. 



In 1880, 36 specimens, representing the types of the 

 "Challenger" Stylasteridse, described by Prof. H. N. Moseley 

 in the " Challenger " Report on the Hydroeorallinse, were added 

 to the collection. 



In 1884, seven beautiful examples of Stylaster roseus Pallas, 

 from the West Indies, from off a cable in 200 fathoms, were 

 purchased from Capt, Cole. The series exhibits beautiful colour 

 variations, the specimens being white, salmon-coloured, and rose- 

 pink. 



In 1892, Mr. Saville Kent presented 21 specimens of 

 Millepora from the Great Barrier Reef, Australia. 



In 1894, 12 specimens of Stylasteridse, mainly from the Gulf 

 of Mexico, were presented by Prof. A. Agassiz. 



POLYZO A. 



The first important addition to the old collection was that 

 of a collection, presented in 1847 by Dr. G. Johnston, consisting 

 of 179 specimens, representing species named and described 

 by him in his "History of British Zoophytes."' 



In 1852, there was published by order of the Trustees a 

 " Catalogue of Marine Polyzoa in the Collection of the British 

 Museum/' Part I., Chilostomata. By George Busk, F.R.S. 

 In 1854, Mr. Busk published Part II., Chilostomata, and in 

 1875, Part III., Cyclostomata. As Mr. Busk states in the 

 preface to Part I., the collection was enriched by the liberality 

 of J. Macgillivray, Charles Darwin, Sir J. Hooker, and others, 

 who placed their collections at his disposal for the purposes of 

 the Catalogue and for the selection of specimens required for the 

 Museum Collection.
