Natica catena, Da Costa. 



Alderi, Forbes. 



Adeorbis sabcarmatas, Mont. Not uncommon. I have kept living 

 specimens for several weeks, and offer the following description 

 of the animal : — Body white with a pinkish hue, semitransparent, 

 easily containable in the shell : stiout rather long, extensile, 

 cloven at its extremity, and of a bright red internally : tentacles 

 diverging, rather long, extensile, blunt, or even a little club- 

 shaped ; upper portion white, lower half pink inside : eyes very 

 small, at the outward base and somewhat behind the tentacles, 

 under cover of the shell, and visible only when the animal is 

 twisting itself : foot slightly notched in front, with rounded and 

 widened corners, nearly square behind ; white, with a pinkish 

 stripe lengthwise along the middle : gill comb-like, on the right 

 side of the body, and not always protruded. 



It is not timid, and swims on its back under the surface of tho 

 water. Some shells are white ; but the greater number are of an 

 ochreous colour.
