66 PENNATULA. 



It is remarkably different from all this kind. From the 

 ftifThefs of its ftem, it is very probable, it is fupported by 

 a bony fubftance. The under fide of its kidney-fhaped 

 body is flat and full of ramifications, which correfpond 

 with the polype mouths on the upper fide, which is a 

 little convex : there are but fix claws to each polype 

 fucker, which proceed from hexangular cells. Dr. So- 

 lander, in his letter to me from Rio Janeiro, on the 

 coaft of Brazil, mentions, that whenever the fifhermen 

 brought them any fhrimps, they were fure to find three 

 or four of thefe among them.

3* Pennatula lanceolata This Sea-Pen has much the 



femice fade, Jlirpe Icevi appearance of a writing pen ; 

 tereti, pinnis creberrimis it is of a long fpear fhape, with 

 imbricatis dentatis virga- a round fmooth ftem \ the up- 

 tis. per part is very clofe fet with

 ftriped.

This curious animal was brought from Batavia by Wil- 

 liam Webber, Efq. F. R. S. Its fins are not unlike thofe 

 of a bat, with feveral iliarp points. They are ftriped 

 black and white, with a mining furface, not unlike fil- 

 ver : they are often found above a foot long, and are faid 

 to be very luminous in the fea at night. There is one of 

 them in the Britifh Mufeum near eighteen inches long. 



In the figure here reprefented, the bone appears to be 

 burft through the bottom, and one of the fins are magni- 

 fied, to fhew it more diftinclly.
