Fig. 3. M. Rana, 



Shell rough, having two opposite compressed 

 varices ; belts muricate ; aperture ovate and ra- 

 ther toothed. 



Lister Conch, tab. 995. fig. 58. 



Specimen reddish brown inclining to cinereous, 

 and much paler towards the varices ; two muri- 

 cate belts on the body ; transverse striae raised and 

 granulate. 



Inhabits Asia. 



The second variety of this species differs so much 

 from the present one, that it cannot properly be 

 admitted into the same section. The varices are 

 spined, the shell is longer, narrower, and more 

 flattened ; the stride little raised, and but few of 

 them granulate. They resemble each other most 

 in colour.
