/Station. On mud banks at low water ; Cuming ! Eeeve. 

 Our specimens were found in the crevices of rocks between 

 the low water mark of the spring tides and of the neap tides. 

 We cannot help suspecting some omission in Mr. Cuming's 

 statement of the station of this species and of M. radix. Neither 

 species was found by us away from rocks or stones, and we can- 

 not well conceive how, without such shelter, the fronds could be 

 protected from injuries. 



Habitat. Peru ; Bligh Catalogue. 

 South Seas ; Wood. 



Acapulco ; Humboldt and Bonpland ! Valenciennes. 

 Panama; Cuming! Sowerby: also Eeeve. 

 Western Coast of Central and South America; 



Penny Cyclopsedia. 



Shores of Peru ; Kiener : also Deshayes.

 Panama ; C. B. A. ! 



We collected 18 specimens on the reef. Only a few were 

 taken, because the species is extremely common in collections. 

 We have since regretted the restriction to such a small number, 

 on account of the fine coloring of the exterior and perfect con- 

 dition of most of these shells. Some of them are also remarka- 

 ble for size. One specimen is 5.3 inches long, and 4.2 inches 

 wide.
