tliis distinction. A large proportion of the localities given by 

 Linnjfius are erroneous. I cannot separate M. Terveria'ta, Petit 

 (fig. 46), from the Island of Socotra and Red Sea. 



M. MILIARIA, Linn. PI. 11, figs. 47, 48. 



White; columella four-plaited, with one or two denticulations 



above the plaits. Length, 4-5 mill. 



Mediterranean ; Portugal ; Canary Ixles ; Gulf of Suez. 

 Is a common fossil in the Upper and Middle Tertiary of 

 Southern Europe. Usually the outer lip is smooth, but occa- 

 sionally it is very slightly, minutely crenulated. M. Savignyi, 

 Issel (fig. 48), from Suez, presents characters so similar in 

 description and figure, that I cannot separate it. 



M. CARNEOLA, Petit. PI. 11, fig. 49. 



Pallid carneous, with two darker bands. Length, 8*5 mill. 



Habitat unknoicn. 



Petit mentions two bands in his description, yet his figure 



only shows a single broad central one. The species has not been 



fully identified ; some authors suspect that it is equivalent to 



and has priority over M. pyi^uluTn, Reeve, the next species ; 



whilst the figure, if correct in representing only one band, is 



more like M. oryza^ Lam. 



M. PYRULUM, Reeve. PI. 11, fig. 50. 



Yellowish white, spire chestnut-color, Avith faint upper and 



lower bands. Length, 7 mill. 



St. Thomas, W. I. ( Reeve j. 

 See remarks under preceding species. The difference between 

 this species and those varieties of M. oryza with apparent spire, 

 is very slight ; both have the dark colored spire. They will 

 possibl}'^ prove identical, 



M. iNFELix, Jousseaume. PI. 11, fig. 51. 



Yellowish white ; columella four-plaited. Length, 7*5 mill. 



Port Jackson, Australia. 

 Described by Reeve as M. simplecc, a name preoccupied by 

 Edwards for a fossil species. 



M. ASELLiNA, Jousseaume. PI. 12, fig. 52. 



Yellowish white, trifasciate with orange-brown. 



Length, 5 mill.
