living specimens by digging in coarse sand at low water mark 

 inside the reefs. It is much more rare at Tonga and Samoa. 

 Mr. Pease records it from the Sandwich Islands. 



The shell Mr. Reeve described and figured as flammea, 

 is not that species, but=J/. Philippinaritm Adams, and his 

 M. flammigera is the flammea^ Q. & G. Mitra foveolata, 

 Dunker, is probably a synonym of the latter. 



"Reeve's description and figure are evidently taken from 

 a discolored specimen. The living shell is a pale olivaceous- 

 grey, mottled and striped with slate color. The aperture 

 and upper half of the columellar lip are blackish-brown and 

 the inner margin of the peristome is whitish. The inter- 

 mediate ridges mentioned by Reeve are not constant.

 fig. 28. 



Obtained in all parts of Polynesia, except the Mar- 

 quesas and Sandwich Islands ; and more abundant at the 

 l>oj Society and Papmotu groups than elsewhere. Invariably 

 j found lurking beneath masses of dead coral on reefs.

 varied with reddish-brown. 



28. Mitra fuiva Swainson. Reeve, 1. c, pi. iv., fig. 24, pi. vi., 



fig- 45- 



Much more rare than the preceding species, and has the 

 same range and station. 



Animal chestnut brown, the creeping disk white and the 

 siphon pale brown. The ocular region and tips of the 

 tentacles, white.

 most common form.
