44 LIMACIDJE. 



3. A. HORTENSIS (inhabiting gardens). 



This slug is much smaller than either of the two last 

 species, measuring one and a half inches in length. It 

 is usually slate grey, striped with black longitudinally. 

 It is "sluggish" to the last degree, being generally 

 found in a state of repose under stones. The shell 

 consists of a few granules. 



Genus II. GEOMALCUS. 



Gr. MACULOSUS (spotted). 



This is a very beautiful animal, only found in the 

 south-west of Ireland. It is described as resembling 

 an Arion in form, two inches in length, glossy black 

 or brown with yellow spots, head grey, foot brownish 

 yellow with transverse stripes, shell oval and solid 

 with concentric lines of growth. 



Mr. Rogers, of Manchester, informs me that he once 

 kept one of these slugs alive for more than two years, 

 in both of which it produced fertile eggs ; the young 

 ones, however, died when they had attained about half 

 their full size.
