EASTERN PROVINCE INTERIOR REGION SPECIES. 243' 



We have noticed its posterior extremity curved upwards wheu the ani- 

 mal was in motion, at other times flattened and expanded, and again 

 very much corrugated and apparently truncated. Sometimes there ap- 

 pear to be one or more mucous glands at this part, and the secretion of 

 mucus from it is more plentiful tbau from other parts of the body. 

 The mantle is not cleft from the respiratory foramen to the margin, as 

 in most of the slugs, but is provided with a deep farrow or canal run- 

 ning from the orifice to the edge of the mantle below it. 



It is very inactive and sluggish in its motions. It inhabits forests, 

 under the bark and in the interior of the decayed trunks of fallen 

 trees, among which it is particularly partial to the basswood {Tilia 

 Americana). 



The varir^^ions from the common coloring are numerous. We have 

 already observed the following varieties : 



a. Whitish, without clouded spots, tending to grayish. 



h. Whitish, slightly clouded longitudinally. 



c. Irregularly clouded with brownish, without any tendency to longi- 

 tudinal arrangement. 



d. With three distinct rows of large clouded spots. 



e. With great numbers of fine black spots. 



/. Gray, with a line of minute black dots along each side. 



g. Blackish-gray, with black lines along each side, and an indistinct 

 line down the middle of the back. 



The appearance of the surface of the mantle is constantly changing, 

 from the play of light on its lubricated eye-peduncles, tentacles, and 

 furrows, which are in almost ceaseless motion. 



There can be no doubt that this is the animal originally described by 

 Bosc under the name of Limax Caroliniensis, though his description is 

 so imperfect that it can only be recognized by the arrangement of col- 

 ors which belongs to it. His original drawing, engraved in F6russac's 

 work, is a tolerably accurate representation of one of its varieties. He 

 makes no mention of the mantle, and it does not appear in the figure. 



An individual of this species kept in confinement deposited about 

 thirty eggs June 20, 1843 ; on the 10th of July the young made their way 

 out of the shell. The eggs were semi-transparent, oval, about one-fifth 

 of an inch in the greatest diameter. The young when excluded were 

 more than a fourth of an inch long, semi-transparent and gelatinous; eye- 

 peduncles and tentacles bluish-black at base, black at tip, the latter 

 very minute m^ b^rdly visible, Body brof^d 5 back whitish, -^tvitU two
