Polynesia ; Zanzibar f 



The longitudinal plications sometimes become obsolete, on 

 which state M. terebralis, Lam. (fig. 136), is founded. It is 

 doubtful whether the latter form comes from Zanzibar ; at any

 foot is reddish brown above, and the siphon is varied with a 

 lighter shade of the same color. Philippi contends that 

 Lamarck's species terebralis is different from the figure bearing 

 that name in Reeve, and so calls the latter M. Reevei ; but 

 Deshayes, in Lamarck, refers to Kiener's figure, which is the 

 same as that of Reeve and Sowerby. 



M. IMPRESSA, Anton. PL 38, fig. 132. 



Yellowish or orange-brown ; sometimes slightly shouldered. 



Length, 1-1-25 inches.

So closely is this related to the M. granulosa,t\i&i, were it not 

 for the difference in locality, I would be disposed to consider it 

 a variety.
