ARIOLIMAX. 155 



Finally, we have in Fig. 135, a representation of 

 the huge yellowish green slug, so common in the 

 woods and damp places along the whole coast of the 

 Pacific states. 



Fig. 135- 



A short evening walk under the trees is almost 

 sure to reveal one or more of these harmless but 

 rather startling creatures, quietly moving over the 

 ground, and leaving a glistening trail in lieu of foot- 

 steps. They frequently grow to the length of six or 

 seven inches, and look as if they were exceedingly 

 well fed. 



As you would suppose, they are seen most in damp 

 weather; for during the dry summers many of them 

 descend into cracks or holes in the ground, though 

 some linger in shady woods, particularly about springs 

 and marshy places. The name of this great slug is 

 Artolmiax Cohimbiamis^ Gould, Co-lum-bi-a'-nus; 

 though there is another slug which scarcely differs 

 externally from this one, but which is considered as 

 a different species on account of a difference in some 

 of its internal organs. The name of this second 

 species, which is not so widely distributed as the first, is 

 A Ho Umax Cali/omiats, Cooper. 



For a careful discussion of these and other obscure 

 points, and for directions concerning an examination 

 of the viscera, I would again commend the student 

 to the " Manual of American Land Shells."
