24 ULABKLLA. 



M. AUREOCINCTA, Stearns. PI. 7, fig. 8. 



Smooth, sutures enameled, spire acutely elevated; white, with 

 two amber-colored bands. Length, '16 inch. 



Long Key, W. Coast of Florida. 



Figured from the unique specimen kindly loaned to me by Mr. 

 Stearns. 



M. DEFORMIS, Nevill. PL 7, fig. 9. 



White, with two spiral chestnut bands. Length, 4-5 mill. 



Ceylon. 



Resembles M. picturata, Nevill, from Mauritius in form, but 

 differs in coloring. 



M. NEVILLI, Jousseanme. PL 7, figs. 15, 16. 



White, smooth, shining. Length, 4 mill. 



Is. of Bourbon ; Mauritius. 



The name adopted is substituted by Jousseaume for M. incon- 

 spicua, Nevill, not Sowerby. I add M. Lantzi, Jousseaume (fig. 

 16), which appears to be a younger state of the same species. 

 The form is so nearly like that of M. picturata, Nevill (fig. 17), 

 from Mauritius also, that I think it probable it will prove to be 

 an unpainted state' of that species. 



M. FUSIFORMIS, Hinds. PL 7, figs. 10-12. 



White, slightly angulated posteriori}^. Length, 4 mill. 

 Straits of Malacca, in mud, at 17 fathoms (Hinds); 



/. Bourbon (Deshayes). 



M. inflexa, Sowb. (fig. 11), described without locality, is very 

 probably synonymous, and I agree with Dr. Weinkauff that M. 

 unilineata, Jousseaume, founded on the shell figured by Reeve 

 for M. fusiformis (fig. 12), and which differs from the type in 

 possessing an inferior revolving brown band, cannot be distin- 

 guished, except, perhaps, as a variety. 



M. HJEMATITA, Kiener. PL 7, figs. 13, 14. 



Smooth, or very slightly pitted, light lilac-red. 



Length, -35-'4 inch. 



Porto Rico, West Indies. 



M. electrum, Reeve (fig. 14), is founded on a faded specimen, 

 in which the lip is worn smooth ; I have similar specimens in 

 the collection of M, hsematita before me.
