334 LIFE BY THE SEASHORE. 



(3) Norman's British Mysidce, a paper in the Annals and Magazine 

 of Natural History (vol. x., 1893), together with some other earlier 

 papers in the same Journal, will be found helpful, but their results 

 are to a large extent incorporated in Stebbing's volume. 



(4) For certain of the lower forms Bate and Westwood's History of 

 the British Sessile-eyed Crustacea (2 vols., London, 1861-8) may be 

 consulted. 



(5) White's Popular History of British Crustacea (London, 1857) is 

 a useful and comprehensive little book. 



MOLLUSCA. 



(1) * Forbes and Hanley's History of British Mollusca. 4 vols. 

 London, 1853. 



(2) Jeffrey's British Conchology. 3 vols. London, 1863-9. 



(3) Alder and Hancock's Monograph of British Nudibranchiate 

 Mollusca. Kay Society, 1845-55. All these works are well illustrated, 

 and should be consulted, if only for the plates. There are many 

 other works of greater or less extent on the British shell-fish, but 

 these may serve for purposes of identification. 



(4) For modern names see Norman's Revision of British Mollusca, in 

 Annals and Magazine of Natural History, vols. v. and vi. (1890). 



TUNICATA. 



Although in Prof. Herdman we have an eminent British authority 

 on this difficult group, his publications have mostly appeared in 

 scientific journals which are not always readily accessible. Brief 

 notes on the British species are included in *A Revised Classification 

 of the Tunicata, etc., published in the Journal of the Linnean Society, 

 vol. xxiii., 1890 ; but this paper will hardly be intelligible to those 

 who have not considerable acquaintance with Tunicate anatomy. 

 The same author's article on Tunicata, in the Encylopcedia Britannica, 

 republished in a volume entitled Zoological Articles (London, 1890), 

 affords a valuable introduction to the subject. In Forbes and Hanley's 

 Mollusca brief descriptions of the external appearance of some common 

 sea-squirts are given. 



FISHES. 



(1) Day's Fishes of Great Britain and Ireland. 2 vols. London, 

 1880-4. 



DISTRIBUTION, ETC. 



(1) A paper on Tlie Fauna and Bottom- Deposits near the Thirty- 

 Fathom Line, etc., by E. J. Allen, in the Journal of the Marine 

 Biological Association (vol. v., 1899), gives a large amount of informa- 

 tion on the distribution of British forms, with very copioiis references. 

 Many of the works cited above also include distribution.
