The specimen sent home (No. 5928) is 46 mm. in length, very 

 much contracted in the spirit and very hard, so that I have refrained 

 from removing it or opening the body to view the genitaUa. 

 Colour darkish grey brown with indistinct mottling. Foot divided, 

 the oblique grooving rising from the peripodial grooves is parallel 

 and very closely arranged. The right shell lobe is small, dark 

 grey, the left is very narrow, even in width all round the edges 

 of the shell, which it overlaps, the absence of any expansion into 

 a flap or lobe is noticeable to be seen in Austenia. The extremity 

 of the foot is square, compressed at the side, with a narrow nearl}^ 

 vertical linear mucous gland. The dorsal lobe is rather small to 

 the left and behind the respiratory orifice, the left is ample, cover- 

 ing the neck and extending round to the left side.
