 the body, with its orifice behind ; the organs of generation, moreover, are distant.

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 

 papilla?. 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.
