Tamija Bay, Fla. 



M. nitida was described without locality, but both description 

 and figure so entirely correspond with M. succineay Conrad (fig. 

 93), that I cannot doubt their identity. M. succinea is figured 

 from the author's t3'pe. 



M. Wallacei, Jousseaume. PL 10, figs. 94, 95. 



Orange-brown with a central white zone ; columella obliquely 

 four-plaited ; lip white, thickened and margined, minutely and 

 irregularly dentate within. Length, 12 mill. 



Locality not certain, probably West Indies. 



The minute lip-denticulations, if permanent, separate this 

 species widely from its nearest allies in form and coloring ; 

 otherwise it is very like a small M. carnea.
