PREFACE, 
Vll 
Mr. Rupert Jones since the publication of the work. For 
many valuable extracts on the habits of the Crustacea, I 
am indebted to the various papers and works of Colonel 
Montagu and Messrs. Gosse, Couch, Kingsley, Goodsir, and 
others. The plates have been drawn by Mr. G. B. Sowerby, 
F.L.S., chiefly from specimens in the cabinets of the British 
Museum. The figures of Entomostraca have been for the 
most part selected with Dr. Baird’s kind permission from 
his volume on the subject. Eor the drawings of all the 
figures in Plate X., as well as for the original figure of 
Peltidium , I am indebted to the kindness of Mr. Spence 
Bate. For various valuable notes on habitats of the many 
rare British Crustacea dredged by the Rev. Alfred Norman, 
and for a few curious notices of the Guernsey Crustacea, I 
am indebted to the Rev. Alfred Norman and Dr. Lukis. 
June 3 1857 .
