Remarks. In shape this species resembles Q. elegans, 

 Pfeiffer, though more nearly like the shell figured by 

 Ferussac as Clausilia suhula, in size and sculpture ; but 

 it is more ventricose, has fewer whorls, a shorter neck, 

 a larger aperture, and a less broadly reflected lip. The 

 animal is very small compared with the shell, being less 

 than one-foui'th the length of the shell, which it carries 

 with its axis nearly horizontal, and in the line of motion, 

 with apparent difficulty. The snout is thrown forward, 

 and firmly attached at every undulation, simultaneously 

 with the contraction of the posterior extremity. When 

 the curve flowing along the sides of the foot reaches the 

 head, the attachment of the snout is released, and it is 

 again thrown forward and fixed as before.
