260 PARASITIC ANIMALCULES. 



capitate tentacles. It is much infested with parasites : 

 a Vorticella grows on it ; and a sort of Vibrio. The 

 latter is in immense numbers, forming aggregated 

 clusters here and there, the individuals adhering to 

 each other, by mutually twisting in several turns 

 around each other, and projecting in bristling points 

 in every direction. These animalcules vary in length, 

 some being as long as—inch, or more; with a diameter 

 of ^^ inch. They are straight, equal in thickness 

 throughout, and marked with distinct transverse lines; 

 they bend themselves about with considerable activity 

 and frequently adhere to the polype by one extremity, 

 or by a small portion of their length, while the 

 remainder projects freely.

The species, I find, has been well figured by M. 

 Dujardin, in the Ann. des Sci. Nat. for 1845, by the 

 appellation of Stauridia; though I do not very 

 clearly apprehend whether he intends this for the 

 designation of the species. If so it must be called 

 Coryne stauridia.
