438 TUBULIPOUID^. 



and shells from tlie coast of Cornwall^ seems to be the one 

 on which Mr. Couch fonnded his T. deflexa. But if so, 

 he has omitted all notice of the adnate and repent portions 

 of thezoarium. His description and figure agree so exactly 

 with the erect and somewhat clavate processes in which the 

 creeping branches of the present species terminate, that I 

 cannot but think that the latter may have escaped his 

 notice. This seems the more probable, as this form is 

 abundant on the coast where his researches were carried 

 on ; whilst, on the other hand, nothing more nearly re- 

 sembling his T. defleoca has occurred there, so far as I 

 know, to those who have followed him. 



In the present species a number of slender creeping 

 branches radiate from a common stem ; and along these 

 the tubular cells are ranged without much regularity, the 

 series never exceeding two in number. Each of these 

 branches terminates in a free portion, somewhat clavate 

 above, at times expanding into an enlarged head, from 

 all sides of which long curved tubes project. Thezoarium 

 is white and thickly speckled.
