SOME BOOKS OF REFERENCE. 333 



(3) Forbes's Monograph of the British Naked-eyed Medusce. Ray 

 Society, 1848. 



(4) For modern terminology reference may be made to E. T. 

 Browne's British Hydroids and Medusce in the Proceedings of the 

 Zoological Society of London, 1896. 



(5) Ellis's Essay towards a Natural History of Corallines (1755) is a 

 carious old book of considerable antiquarian interest. 



(6) Johnston's History of British Zoophytes (Edinburgh, 1838) is 

 comprehensive as regards the ground covered, but the descriptions in 

 most cases are too vague to be of much use. 



B. ACTINOZOA. 



(1) * Gosse's History of the British Sea-anemones and Corals 

 (London, 1860) is the standard work on the subject, but for the 

 modern names of the British sea-anemones reference should be 

 made to 



(2) A Revision of the British Actiniae, by Haddon and Shackelton, 

 in Transactions of the Royal Society of Dublin, 1889 and 1891. 



We are unfortunate in not possessing books which deal with the 

 British representatives of such forms as the allies of Dead Men's 

 Fingers (Alcyonium), Lucenaria, the large jelly-fish, the Ctenophora. 

 and so on. Some of these are dealt with in Johnston's British 

 Zoophytes. 



WORMS. 



(1) The volume called * Worms, Rotifers, and Polyzoa, in the 

 Cambridge Natural History (vol. ii., 1896), by various authors, is an 

 admirable introduction to the subject, especially as regards the Marine 

 Bristle-worms. It contains numerous references which will enable 

 those interested to pursue the subject further. 



(2) Mclntosh's British Annelids (Ray Society, 2 vols., 1873 and 

 1900) treats in detail of the British species of Nemerteans and certain 

 families of Bristle-worms. 



(3) Johnston's British Mu'seum Catalogue of Non-parasitical Worms 

 (London, 1865), though not very full, and vague in its descriptions, is 

 helpful in some ways. 



ECHINODERMA. 



(1) The standard work of reference is * Jeffrey Bell's Catalogue of 

 British Echinoderms in the British Museum (London, 1892), but it 

 will probably be found difficult to use. 



(2) Forbes's British Starfishes (London, 1841), thougnout of date, is 

 well worth reading on account of the interest of the style. 



CRUSTACEA. 



(1) * Bell's History of the British Stalk-eyed Crustacea (London, 1853) 

 is the standard work on the higher forms, but it should be sup- 

 plemented by 



(2) Stebbing's History of Crustacea. London, 1893. International 

 Science Series.
