some Zostera marina that had been cast ashore. It is consequently 

 an inhabitant of shallow water. 



" This species ? is like what the central portion of Tubulipora 

 patina would be if set on a flat base and wanting the marginal series 

 of erect tubes. In the course of drying the Zostera containing this 

 zoophyte, (and which was done very gradually in a cool place,) the 

 specimens of Tubulipora bellis dropped off from their fragile base, 

 which still remained attached to the plant." W. Thompson.

Hob. Parasitical on Flustroe, on sea-weeds, (chiefly Delesserite 

 and Nitophyllae) on shells and rocks. " On a plant of Griffithsia 

 setacea I have an interesting specimen, in which, as if from want of 

 room to fully expand itself, the polypidom assumes above the form 

 of a double circle, and the marginal base folds in, so that taken alto- 

 gether, we have somewhat the appearance of the scroll or volute of 

 an Ionic pillar," W. Thompson. Similar specimens are not rare on 

 Sertularice, and narrow-leaved sea-weeds. In Mr. W. Thompson's 

 herbarium, there are specimens on various species of Algae from Van 

 Diemen's Land. 



" Breadth nearly an inch, hispid ; the cells seem distributed over 

 the whole surface, and more vertical than the preceding (T. patina); 

 there are, however, waved porous grooves, and the cells seem dis- 

 posed on each side of these in irregular transverse rows, united or 

 free, short, with expanding orifices, dividing into irregular spinous 

 processes." Fleming. 



* He was " Minister of the Episcopal chapel at Bamff." Encouraged by Pennant, 

 he published two volumes illustrative of the Antiquities of Scotland. In one of 

 these, entitled " Remarkable Ruins," he gave figures of several Scottish animals but 

 without descriptions, " in illustration of the designs of his pencil/' Fleming, Brit. 

 An. p. 504. I have not seen this work.
