86 MELVILL AND STANDEN: SHELLS FROM LIFU. 
catalogue brought up to date ofall the species hitherto reported 
from this group; but, upon reflection, we think it best merely to 
include those species received from time to time from Mr. 
Hadfield. Our especial thanks are due to Mr. William Moss, 
Mr. R. Cairns, and Dr. G. W. Chaster. To Mr. Moss, for 
photographing for us some of the new species in a very clear and 
accurate manner, and for allowing us to inspect, on several 
occasions, the large stores he received from Mr. Hadfield. To 
Mr. Cairns for having aided Mr. Moss in the separation and 
arrangement of so large a mass of material and for having per- 
mitted the selection by us of what might be of interest for this 
catalogue; and to Dr. G.W. Chaster also for some beautiful photo- 
graphs of the new species, reproduced herewith by the collotype 
process. Thisaid has been to us invaluable. To Mr. Edgar A. 
Smith, F.Z.S., of the Natural History Museum, South Kensing- 
ton, and to Mr. Ernest Ruthven Sykes, F.Z.S., we must also offer 
our best acknowledgments, for their ready help in discriminating 
some of the more critical species, and advice on the subject of 
the new forms ; andto Mr. John Ray Hardy, of the Manchester 
Museum, Owens College, we are also indebted for much yalu- 
able assistance in the arrangement of the collection generally.
