Description. Body flattened towards its posterior extremity, which is obtuse. Mantle 
fleshy, and falling in a slight curve between the two superior tentacles, reaching on the sides 
to the superior margin of the foot, rounded behind. Surface covered with irregular vermiform 
glands, assuming a general longitudinal direction, with shallow furrows between. Foot 
extending a little beyond the mantle behind. Mouth surrounded with a circular row of 
papille. Orifice of the organs of generation on the right side, at a little distance behind 
and below the superior tentacle. Breathing-hole large, a fourth of an inch behind the origin 
of the upper tentacle ; vent in close contact, a little above and in front of it. Above the 
breathing-hole, on the back, is a deep curved furrow, running upwards and backwards. 
Upper tentacle long and stout, ending in a bulb; lower short and conical. Locomotive band 
not distinguishable from the lower surface of the foot. 
Color. Whitish or yellowish white, variegated with clouds and spots of brownish and 
blackish, so arranged as to form three ill-defined longitudinal bands the whole length of the body, 
anastomosing more or less with each other, with smaller spots of the same color between 
them ; lower margin white or yellowish. Upper tentacle brownish or blackish. In some 
specimens the body is irregularly clouded with brownish, or with numerous black spots, or 
with clouded spots in regular series. 
Greatest length when extended, 4:0. 
This species was first noticed by Bosc in South-Carolina. It has since been observed in 
Vermont, Massachusetts, New-York, Ohio and Missouri. According to Mr. Binney, it is 
very inactive and sluggish. Found under the bark of trees, and appears to be partial to the 
Tilia americana, or Basswood.
