 synon3'moiis. 



M. Chapert, Jousseaume. PI. t, fig. 21. 



Yitreous white, or cream-color. Length, 7 mill. 



Habitat unknown. 

 A ver}- doubtful species. 



M. PUMiLA, Redfield. PI. T, fig. 28. 



Pallid corneous. Length, 5 mill. 



Port Louis Harbor, Mauritius. 



Described \)x A. Adams as M. jjusilla, a name preoccupied by 



Edwards for a fossil species. Jousseaume, in ignorance of the 



substitution made by Redfield, proposed for it the name 3f. 



Borhonica. 



M. SERRATA, Gaskoin. PI. *?, fig. 31. 



White; columella four-plaited, lip closely denticulated.

M. sciNTELLA, Jousscaume. 



An unfigured species, from an unknown locality, and referred 

 by its author to his genus or group Serrata., which includes M. 

 i^errala.1 Gaskoin. In the absence of authentic figures or speci- 

 mens, it is not determinable. 



M. OsTEBi, Jousseaume. PI. 7, fig. 32. 



White; columella four-plaited, lip minutely- denticulated. 



Length, 3'8 mill.

White. Length, 7-5 mill.

31. Strangei, Angas (fig. 30), is evidently a synon3'm, and I 



place here also M. pygmeea.^ Sowb. (fig. 35), described without 



locality, from a single specimen in the Bell collection. It is the 



31. attenuata^ Reeve, of Weinkauff, and has also been sent to me 



by Australian collectors under that name, but Reeve's species 



is entirel}' different and does not belong in the same group.
