104 CATALOGUE OF THE ZOOPHYTES OF 



head, surrounded by a single row of tentacles. Pohjpary 



tubular, yellowish horn-coloured, strongly wrinkled across 



but not annulated, slightly branched and expanding a 



little towards the apertures; base a densely reticulated 



and closely adhering crust. Height J to J an inch. 



On old shells of Buccimim undatuni and Fusus antiquus from 



deep water, Cullercoats. 



This little zoophyte appears to have been first noticed by Dr. 



Johnston, though he had subsequently overlooked or forgotten it, 



as he has not introduced it into his " British Zoophytes ;" and when 



I sent him the description of a specimen got at Cullercoats in 



1854, he wrote me that it was something he was unacquainted 



with. I have since, however, found in his " Catalogue of the 



Zoophytes of North Durham," published in the Transactions of 



the Newcastle Natural History Society, mention made of a 



zoophyte which is undoubtedly the same as this ; and the descrij)- 



tion is so characteristic, that I cannot do better than adopt it. 



" I have observed," he says,* "a small Tubularia which invests 

 old specimens of Murex antiquus with a dense beard-like coat, and 

 may, possibly, be a species distinct from the above (T. ramosa). 

 It is only the quarter of an inch in height, slender, horny, wrin- 

 kled, slightly and irregularly branched, the branches without 

 rings at their origins: polypes white, furnished with a single 

 series of obtuse tentacula, which do not seem to exceed ten in 

 number. In this respect it agrees with T. ramosa^ as character- 

 ised by Dr. Fleming, but differs from the specimens which I 

 have seen, and also from Ellis's figure of it, in which the tenta- 

 cula are much more numerous." The encrusting base, which Dr. 

 Johnston does not appear to have examined, forbids our consi- 

 dering it the young of Eudendrium ramosum. Tlie basal ramifi- 

 cations are corneous, and more solid than the ascending stems, 

 rather broad, flat, and undulating in outline, forming a dense net- 

 work. The spaces between the larger reticulations being nearly 

 filled up with smaller ones, and the whole, in old sj)ecimens, 

 apparently united by a membrane. This latter is rather difficult
