Some mouths ago Professoi- A. C. Haddon presented to the 

 University Museum of Zoology at Cambridge a collection of 

 Polyzoa, obtained by him during his first expedition to 

 Torres Straits in 1888-9. The bulk of his collection 

 had previously been given to the British Museum, and had 

 formed the subject of a paper by Mr. R. Kirkpatrick ;^ but 

 the material acquired by the Cambridge Museum, although 

 consisting mostly of small pieces, contained many species 

 which do not seem to have been represented in the other 

 part of the collection. Among these I observed three species 

 of Steganoporella, two of which appear to be undescribed. 

 One ol these was of special interest from being well pre- 

 served in spirit, enabling observations to be made on its 

 structure. My results on this subject are not quite ready 

 for publication, and I shall at present merely indicate their 

 general nature. 



In drawing up an account of the genus Steganoporella 

 I have made use of the following collections : — (1) the speci- 

 mens brought by Professor Haddon from Torres Straits; (2) 

 other specimens in the Museum of Zoology at Cambridge, 

 mostly presented by Miss Jelly; (3) the collection of the
