North American Land Snails 



reflexed, epiphragm secreted by certain species, but not a constant 

 character. A large genus distributed on the Pacific slopes of 

 America. 



The Faithful Snail {E. fidelis, Gray) has a low cone with 

 rounded, smooth whorls banded with brown. Basal area of body 

 whorl dark brown to black. The umbilicus is open, but contracted 

 at the top by the flaring of the lip. Epidermis yellowish. Dia- 

 meter, I to I J inches. Late broods are often found tucked away 

 in holes in the trunks of maple trees, far above the ground. 



Habiiat. — Vancouver Island to California. 



E. Mormomum, Pfr., has a more flattened spire. The thin 

 body whorl, pale reddish, with arching striae, is adorned by a 

 chestnut band, doubly edged with white. The aperture is ear- 

 shaped and oblique, its rim white and recurved. Diameter, i 

 inch; height, ^ inch. 



Habitat. — Mountains of California. 



The Point Cypress Snail (£. Dupetithouarsi, Desh.) is low- 

 spired, its seven brown whorls decorated with a yellow-edged, 

 almost black median band. The body is grayish, and warty. 

 Diameter, J inch. 



Professor Keep found these snails asleep in debris under the 

 gnarled old veteran cypresses of Monterey. They were dormant 

 in the drought of summer, and many shells were empty, punctured 

 by hungry jays. The living ones became quite active when put 

 into a damp fernery, and sprinkled with water. 



E. sequoicola, Coop., which lives among the red-woods 

 near Santa Cruz, has a more elevated spire, roughened by fine 

 ridges, and granulated about the apex. 



E. Traskii, Newc, and E. Carpenteri, Newc, each wears 

 a band of brown, edged with yellow or white, on a horn-coloured, 

 striated surface. The latter is more delicately built throughout. 

 Diameter, less than i inch. 



Habitat. — Southern California. 



E. Coloradoensis, Strns., is low-spired, fragile and pale, 

 with a narrow red band. The mouth is large. It was found at a 

 high elevation near the Grand Caiion of the Colorado. Diameter, 

 f inch. 



The Dented Snail (E. arrosa, Gld.) has a more solid and 

 elevated spire than the preceding species, with a dark band on the 

 yellowish brown coils. The rough surface has furrows of different
