PREFACE

[v]

This sketch of the Natural History of the Crustacea deals chiefly withtheir habits and modes of life, and attempts to provide, for readersunfamiliar with the technicalities of Zoology, an account of some of themore important scientific problems suggested by a study of the livinganimals in relation to their environment.

I am indebted to the Trustees of the British Museum for leave toreproduce certain figures prepared for the "Guide to the Crustacea,Arachnida, Onychophora, and Myriopoda exhibited in the Department ofZoology"; also to Sir Ray Lankester, K.C.B., F.R.S., and to Messrs. A.and C. Black for the use of a number of figures from my volume onCrustacea in the "Treatise on Zoology," edited by Sir Ray Lankester.

The source of these figures is indicated in the explanation attached toeach. Of the remaining illustrations, some are reproduced fromphotographs of specimens in the collection of the British Museum; theothers have been drawn from Nature, or copied from the original figuresof various authors, by Miss Gertrude M. Woodward, to whom I am muchindebted for the care and skill which she has given to theirpreparation.
