FiGUKE 9 



Diagnosis: Lithoglyptes female with mantle aperture armed with 

 a pair of conical processes near the dorso anterior angle; cones not 

 equipped with long simple spines, but with numerous small granu- 

 lations and stout simple or bifid teeth. Lateral bar weak. Mantle 

 studded with teeth of appreciable size. Orificial knob present. 



Etymology: mitis (L.), mild, without spines, because of the lack 

 of spines on the operculum.

 Veti Levu, Fiji, from the Australia Museum collection, designated 

 holotype. Two specimens from Ricinula rubicunda from Nadi Bay,
