PREFACE. 
The Editor has again the pleasure of thanking the Recorders, to 
whom the appearance, without undue delay, of this volume is due. 
Special thanks are owing to Mr. A. W. Brown, of Christ Church, 
Oxford, who had only a short time in which to prepare his work. 
It will be generally regretted that Mr. P. A. Bather has been 
unable to furnish his Record of Echinoderma , owing to his leaving 
London in the summer as a delegate to represent the British 
Museum (Natural History) at the International Geological Congress 
in St. Petersburg. The Record of the literature of Echinoderma 
for 1896 will therefore appear in combination with that for 1897, 
in the next volume of the Zoological Record. 
Mr. J. Walker, the Librarian of the Radcliffe Library, having, 
at the request of Miss Buchanan, been so kind as to mark a 
list of our periodicals, we have been able to add to the list 
indications of those works in it that are contained in the Library 
in question. 
For several years past the Volumes of the Record have been 
very bulky. We have therefore now adopted a different method 
of arrangement of the type, so that the number of pages in this 
volume is considerably reduced. 
D. SHARP.
