reprefents our fliell. Although this is the firft infiance of ii-s

In the cabinet of ]\fr. Laskey is the finefl fpecimen of Seiipula 

 grooped SerpuLi tubularia we ever faw; the tubes ftand inTucuLARjA. 

 four detached parcels on an old valve of Maclra ItUraria, tlie 

 largefl of which contains not lefs than twenty three, and all 

 ftand nearly perpendicular. Some have their apertures con- 

 fiderably fpreading, or fub-infundibidiform,and extend nearly 

 four inches in height, and not lefs than a quarter of an inch 

 in diameter ; and in two or three inftances, an acute ridge 

 or belt is obferved to furround the fliell : the base is con- 

 fufedly entwined, and mixed with Serpula triquetra. Several 

 fpecies of Coraliina are alfo attached to it. 



This fpecimen was originally taken by dredging off the 

 coaft of E-jJex, and preferved in the Leverian Mufeum. The 

 fliell, together with the Amphitrite that inhabits it, were for 

 the firlJ: time defcribed in the former part of this work. The 

 examination of fucli a fpecimen as the aboVe in its native ele- 

 ment, with all its beautiful congregated inhabitants extend- 

 ing their numerous ciliated arms in radiant order, would 

 have been a fpe61;acle of more than common attradion to 

 the philofophic eye.
