1834.] Notice of Land Shells of India. 521 



Shell — with six whorls, globose, and the body whorl forming the great- 

 er portion of the shell. 



In the living animal it is mottled with pale brown and black, from the 

 thinness of the shell rendering the colours of the animal visible ; 

 but when dead, wholly of a dull white : — spire very little raised above 

 the whorls ; aperture lunated, margins acute ; diameter 9 lines. 



The animal stops up the mouth of the shell with a hard calcareous oper- 

 culum, but which is only temporary, not being attached to the body. 



Found buried in the earth with the foregoing beneath shrubs, in un- 

 cultivated grounds, between Nemuch and Mhow. 



29. Helix 



Animal — with four tentacula, the superior longest and bearing the eyes at 

 their summits ; foot elongated and rather truncated posteriorly ; 

 colour pale yellowish brown. 

 Shell — with six whorls; spire moderately raised above the plane of the 



whorls ; colour sandy ; diameter, half an. inch. 

 Found with the preceding. 



These two specimens appear to be true Helices. — Unlike the species 

 No. 3, described in the 26th No. they have no tentaculiform processes 

 on the right side, playing over the surface of the shell when the ani- 

 mal is in motion, nor have they the fleshy hook on the tail. 

 The shell of the species which I formerly described w T ith a mark of 

 doubt as a Helix, is very like in form and general appearance to the 

 present species, No. 29 : but the polish of the shell is very superior 

 to this last. 



30. Achatina ? 



Animal — unknown. 



Shell — with 10 whorls ; pale sandy brown ; spire obtuse ; cylindri- 

 form ; aperture longitudinal, subovate, right lip edged ; pillar 

 smooth, straight, and truncated at the base; length, li inches, 

 smooth and shining. 

 Found buried in the earth, foot foremost, at the roots of shrubs, in un- 

 cultivated grounds, between Nemuch and Mhow. 

 Among these shells, I could observe no partiality for any particular 

 aspect, nor any thing to confirm the opinion which I formerly hazarded, 

 of this being one of the habits of the Land Shells. Nevertheless, I am 

 still inclined to retain that opinion, because the circumstance may hold 

 good with regard to those species which are more particularly found in 

 rocky situations, and where the hot winds, striking throughout the 

 dav against the rocks, would of necessity impart a great and over- 

 powering degree of heat to the retreats of these animals, even when
