PLEUROTOMARIA ADANSONIANA (Crosse and Fischer). 



RECENT. 



Tobago - West Indies. 



The dimensions of this rare shell are as follows : — Total height, 162 mm. ; greatest diameter, 

 163 mm. ; height of aperture, 53 mm. ; width of umbilicus, 30 mm. ; length of fissure, 235 mm. ; 

 width of fissure, 5 mm. This, therefore, is the second in size of the specimens of recent 

 Pleurotomaria in existence. It is in almost perfect condition, and looks as if, when found, it 

 had had the living animal still in the shell. [The specimen was purchased from Mr. Guppy, and 

 is now the property of Mr. Robert F. Damon, of Weymouth.] 



Reproductions of the above beautiful and extremely rare shell have been prepared by an 

 experienced London Formatari, and coloured facsimile by a well-known artist, and are now 

 being supplied by 



Mr. ROBERT F. DAMON (Weymouth). 



N.B. — These casts look exactly like the original, only cleaner.
