Genus Liotia, Gray. 



Liotia armata, A. Adams. 



L. testa turbinata, alba, solida ; spira elata, conica, late umbilicata ; 

 anfractibus convexis, lougitudinaliter corrugato-lamellatis, lamellis 

 confertis undulatis ; anfractibus carinulis transversis (in anfractu

Hab. Korea Strait ; 46 fathoms. 



Most like L. muricata, Humph., but with two series of squa- 

 mose spines, and the form of the shell turbinate instead of coni- 

 cal ; it is also devoid of colour, and the spines are longer and 

 more aculeate than in that species. 



Genus Cynisca, H. & A. Adams. 

 In our ' Genera of Recent Mollusca,* vol. i. p. 406, my brother 

 and myself proposed a subgenus of Cyclostrema under the name
