others it may be examined with a vievv to determine its 

 real character. It has exactly the liabits of Lagotis, but 

 is far smaller, not being above a quarter of the size of 

 the smallest specles of that genus. It lives in a small 

 tube on the surface of zoophytes and algce, from which it 

 slowly protrudes a single spiral ciliated lobe, resembling 

 that of Chcetospira (Lachmann). It may belong to this 

 genus, but 1 have never been able to isolate the tube 

 in which it lives, and consequently cannot say what 

 relation it bears to that anlmal. The habits and general 

 appearance are so like those of Lagotis, that I should say 

 that it was closely related to that genus.
