PREFACE TO THE FINAL VOLUME OF THE 
MONOGRAPH. 
In concluding this monograph of the British Marie Annelids the author is aware 
that there are many gaps to fill in literature, anatomy, physiology and development, 
but he hopes that they are left in a better state than he found them, thanks to the greater 
attention zoologists in every clime have bestowed on the Marine Polychets since he took 
them in hand. Indeed, as formerly stated, it was their neglected condition in the later 
fifties and early sixties of last century which prompted him to attempt something for their 
improvement. At least the treatise will give a foundation to the work of those who may 
follow, and conserve the time and labour so readily absorbed in the study of the group. 
Tio previous workers in this country, such as Borlase, Montagu, John Graham 
Dalyell, George Johnston, Wm. Baird and Thomas Williams, he would render a grateful 
tribute, whilst abroad the valued labours of O. F. Miller, O. Fabricius, H. Rathke, Delle 
Chiaje, Milne Edwards, Grube, De Quatrefages, Michael Sars, Clapartde, Alex. Agassiz, 
Leidy, Stimpson, De St. Joseph, Marion, Giard, Langerhans and many others! keep their 
memories ever fresh. 
To the zoologists in the early sixties of last century who cordially supported the 
study of the Marine Polycheets, viz., Professors Allman, G. Busk and TT. Huxley, Lord 
Avebury, Dr. Baird, Mr. Spence Bate, Dr. Gunther and others, | owe much, and to none 
more than Prof. G. Busk. Moreover, the care taken by Dr. Gwyn Jeffreys and Canon 
Norman in their various dredging expeditions to secure good specimens merits grateful 
record. 
Much good work has recently been done by Mr. Southern on the rich western coasts 
of Ireland, where rare and new species have rewarded his investigations under the Irish 
Fishery Department. In the same way the facilities for research on the southern coast 
afforded by the Marine Biological Laboratory at Plymouth have added largely to our 
knowledge, and the labours of Prof. Goodrich, Dr. Allen, Mr. Potts, Dr. Orton and others 
of the staff deserve special commendation. In the same way the increased facilities offered 
by the ships of the Fishery Board for Scotland have enabled Wm. Small and James Watson 
Pryde to extend our information of the Polychets. The work of Mr. Arnold Watson, as 
well as his ready courtesy in sending specimens and figures, and this throughout many 
years, has likewise been a noteworthy aid. Sir Ray Lankester, Prof. J. Arthur Thomson,
