AIR-BREATHING SNAILS AND SLUGS 281 



edged with equal stripes of light yellow. The ani- 

 mal is slate-colored, and its surface is covered with 

 numerous little elevations. The diameter of the shell 

 is about three-fourth ot an inch, though specimens 

 are occasionalh' found that are somewhat larger. 

 During the past summer a box of fine live specimens 

 was given me by a lady in Pacific Grove, who had

 placed these in a snailery, and hope to induce them 

 to live and multiply. 



Epiphragt72ophora sequokola^ Cooper, is the Red- 

 wood Snail. This species resembles the last in size 

 and general form, but it has a more elevated spire. 

 The surface of the shell is not smooth, but is some- 

 what roughened by cross lines, while the upper 

 whorls have many crowded granulations. It is found 

 in wooded regions in the vicinity of the coast, near 

 Santa Cruz. 



Epiphragmophora traskii^ Newc, Trask's Snail, 

 comes from the coastal regions of southern Cali- 

 fornia. It has a small umbilicus, six whorls not 

 greatly elevated, which are dark horn-colored, and 

 bear a chestnut band that is edged on both sides with 

 white or vellow. The surface is marked with micro- 

 scopic striae. The diameter of the shell is usually 

 less than an inch. There are several varieties. 



Epiphragmophora carpenteri, Newc, Carpenter's 

 Snail, comes from San Diego and Mexico. It resem- 

 bles the last species, but has a more delicate shell. It 

 is a decidedly southern form of snail. 



Epiphragmo phora coloradoensis, Stearns, the 

 Colorado Snail, was originally found near the Grand
