the exception of the head and funnel, and showed many important 

 points in the anatomy of this rare Cephalopod, more particularly with 

 regard to the relation between the shell and the animal. The broken- 

 off ' neck ' lay deep down within the cavity of the mantle, and, by its 

 distance from the mantle-edge, gave some indication of the depth of 

 the pallial inpushing upon all sides of the neck. The fins, which 

 occupy a peculiar position at the extreme hinder end of the body, 

 were also well preserved. They lie in the vertical plane, extending 

 backwards on either side of a central boss-like disc, which, from its 

 form (being excavated in the centre), has been regarded as a sucker, 

 though probably without good reason. The shell, although almost 

 completely covered by overgrowths of the mantle, is exposed through 

 two oval windows with smooth unbroken margins, one in the dorsal 

 and one in the ventral body- wall. Through the dorsal window could 

 be seen the last whorl of the shell, and through the ventral one its 

 older coils. The shell was thus clearly seen to be vertical in position 

 to the body, and coiled towards the ventral side (endogastric). 



The second specimen consisted of the same parts, but was not in 

 so perfect a state of preservation as the first. Both specimens are in 

 the stores of the College of Surgeons Museum, and probably formed 

 part of the material dissected and described by Owen.
