The apex, which, in Cymha^ was abnost a shapeless 

 mass, takes in Melo a well-fashioned and spirally marked 

 form. With this first appearance of the mammillary 

 summit begins the elegant and vivid colouring which is its 

 almost constant companion. The suture of the spire, no 

 longer rude, is either neatly laid down around the apex, 

 so as to touch it, and in some instances overwrap it, or, 

 as in the coronated section, is free and adorned with a 

 diadem of vaulted spines. 



The shell of Melo is ventricose, light, melon-shaped, 

 and floats when placed with its back on theVater. It is 

 generally marked with a well defined variety of colour, 

 and covered with a smooth greenish brown epidermis,* 



* Lamarck speaking of his Genus Volutay says Les esp^ces sont en 

 g^n^ral lisses, brillantes, et il ne pardit pas qu aucmie d*elles soit pourvue aun 

 drap marin" The writer who has ventured to propose these new Genera hopes 

 to be enabled to shew that most, if not all, of Lamarck's Genus Volutay arc 

 provided with a " drap marin."
