EDITOR’S PREFACE. 
Tiie staff of the Recorders has Undergone some alteration, owing 
to the retirement of Dr. Fowler and Prof. Sollas. Their places 
have been taken by Mr. P. Chalmers Mitchell, Mr. 0. H. Latter, 
and Mr. C. Warburton. Mr. Mitchell has recorded the Vermes for 
the present volume ; Mr. Latter the Echinodermata and Spongia ; and 
Mr. Warburton the Crustacea and Protozoa. Mr. Arthur Thomson 
found himself unable to continue recording the last-mentioned 
group and Ceelenterata. Mr. Hoyle has supplied the Record of the 
Ccelenterata , in addition to those of the groups which he recorded 
in the last volume.
