BRITISH ZOOPHYTES. 179 



1. C. Lloydii, Gosse. ''The Vestlet." 



Edwardsia vestita, C membranaceus (P. H. G., Von 

 Heider), C. Borealis {Daniellson). 



Hab, : Menai Straits (E. Edwards, A. S.P.), Herm 

 (Holdsworth), St. Andrews {Mcintosh). Length to 

 7 m. 



Colour. Pale buff to chestnut-brown. Tentacles 

 chocolate-brown, with white and chestnut bands. 



The marginal tentacles are arranged in two rows, 

 and are 64 in number. The oral tentacles are in four 

 irregular circles. 



The peculiarity of this species is the investing tube, 

 which can easily be detached. It is largely composed 

 of " cnidge, the discharged ecthorea of which intertwine, 

 and form a sort of felt.'^ 



It is a difficult species to secure, as it readily retires 

 into and even slips through its sac and escapes. The 

 ■only way to secure it is to have two or three spades so 

 as to raise the ground on all sides at once. 



The anatomical characteristics of this species have 

 been investigated by Professors Hertwig, and more 

 recently by Von Heider.* Herr Gr. von Kock has 

 discovered that the tentacles have a series of fissures 

 or openings for the discharge of water, a fissure being 

 placed between every two of the dark ring-like bands.
