early suimer months over a period of six to eight weeks, possibly 

 triggered by onset of wami weather. 



Morphology of the shell was described by Sellards (1906) as 

 smooth, white or coneous white, with about four bands of brown spots. 

 Old shells often have corroded surface, the bands becoming indistinct 

 or absent. 



Physical requirements . The order Stylommatophora or terrestrial 

 air breathing mollusks have learned to control water loss by frequenting 

 areas of high environmental humidities (Edney, 1960). Boycott (1934) 

 found only 12 obligatory hydrophiles and eight species of xerophiles. 

 Hunger (1964) stated that water is primarily lost through general 

 evaporation from the moist skin, but some loss resulted from the con- 

 tinued pedal secretion of mucus for locomotion. The land snails are 

 active at night or just after rain (Binney, 1878). Binney also mentioned 

 the epiphram, a semitransparent membrane-like structure, which is 

 secreted by the snail during hibernation to attach the shell to substrate 

 and help reduce water loss. 



Griffiths describes the onset of hibernation in December coinciding 

 with winter cold. Activity is reinitiated in the spring. He also 

 suggested that breaking of dormancy may have to do with tree growth 

 and availability of water. 



The "resting stage," that period when the snail is withdrawn into 

 the shell, is generally divided into two categories. The first is for 

 the purpose of hibernation. Hibernation is usually for overwintering 

 and the mouth of the shell is sealed by secretions of calcareous 

 material and hardened mucus termed the "epiphragm" (Hunter, 1964). The 

 second type of "sealing off" occurs daily during unfavorable conditions.
