Letters fhew$ and in the Year 1744, it was 
taken Notice of by Mr. Trembley , who gave 
it, in his Memoires, the Name of the Polype d 
Pannaehe , or the Plumed Polype . My Friend, 
who difcovered it in his Searches for the 
Polype , called it the Bell-Flower Animal >

themfelves, wdiich living with me feveral

deferibes, they may pofiibly be of another 
Species, though of the fame Genus.
