STEM, when fully extended, cylindrical and slender, capable 

 of great elongation and contraction, invested by a deli- 

 cate transparent film ; POLYPITE somewhat globular ; 

 capitate tentacles 5, filiform tentacles 9. 



THE transparent layer which covers the body of the poly- 

 pite ' ' extends from the foot, where it forms a thick mass, to 

 a ridge which runs beneath the insertion of the lower row 

 of tentacles." 



The zoophyte, as it occurred to Dr. Wright, was solitary, 

 and had the power of changing its place. But, as I have ex- 

 plained, his specimens were probably immature, the pri- 

 mary polypites of a species which is compound and fixed in 

 its perfect condition. It maybe identical with the Devon- 

 shire form to which I have referred before ; but in the 

 present state of our knowledge nothing can be said with 

 certainty of the species of Vorticlava. A glance at the 

 figures of V. proteus will show that it well deserves its 

 specific name.
