angulatis; apertura lata; columella callosa, expansfi; labio cx- 

 terno crasso intiis irregulariter crenulato, extus margiue rotuudato, 

 vix canalifero. 



The spire is rather more produced than in M.Cnmrngii, the colu- 

 mella is tumid and spread over a large portion of the body whorl ; 

 the crenidations on the inner lip are irregular, and the outer margin 

 is rounded instead of being short as in 31. Cumingii.

M. ovali, ventricosa, Isevi, rubra vel brunnea, prope suturam 

 prsecipue, maculis albis conspersa ; spira conica, obtusa, anfractibus 

 vix rotundato-angulatis ; apertura pyriformi, columella valide quad- 

 ripHcata, plicis obliquitate versiis basin crescentibus ; labio externo 

 crasso, intus creuulato, postice emarginato, tum in angulum incur- 

 vum producto, antice leviter emarginato. 



Oval, veutricose, smooth, of a red or dark brown colour, wliicli 

 is darkest near the suture, sprinkled with roundish wliite spots, 

 those near the suture larger and irregular ; the spire is conical, 

 with the apex obtuse and the wdiorls slightly rouuded ; of the four 

 folds on the columella, those nearest the anterior termination are 

 the most oblique, the last nearly vertical ; the outer lip is hollowed 

 out near the suture and then bends forward into a sort of angle.

Differing from M. glabella, in being of a more regular form, in 

 having the outer lip more thickened and more straightly reflected, 

 and in having the folds of the columella much thinner and in the 

 large size of the wliite spots.
