46. MiTEA (Pusia) dicheoa, Ad. Sf Rve. 



This species, with M. tricolor, Montr., M. Grceffei^ Cr., 

 M. Icevizonata, Sow., and others, is merged by Tryon in Pusia

1S.0 full-grown specimens were in the collection, but a large 

 operculum, and a mass of nidamental capsules, containing, 

 roundly speaking, fully one hundred and twenty embryonal 

 young. These are all, without exception, decollate, seven- to 

 eight-whorled, averaging 30 mm. longitudiDally. The canal is 

 fairly long, the last whorl showing a little of the adult sculpture, 

 and slightly tumid.
