The animalcules inhabiting it had the follow- 

 ing ihape : 



They are of the 'Triton kind, and have 

 ten pair of comb-like arms, which are bent 

 towards each other like fkrews, are black or 

 grey, connected together at bottom, and are 

 an inch long ; each pair is inferted below, 

 and entire. Befides thefe ten pair of arms, 

 there is a {ingle arm in the middle, like a 

 worm, which is hairy at the top, and is per- 

 haps the initrument they make ufe of to bring 

 that kind of food to their mouth which they 

 catch by their tentacula. Befides, there are 

 a pair of arms on each fide, which are like the 

 abovementioned ten, but (land a little more off, 

 are ihorter, and as clear as water. The mouth 

 confifts of feven valves, which are ferrated on 

 the infide : on the fides of the mouth are fome 

 fcales, that are like the former; they all 

 ftick to an oblong bladder : the ihell flicks to 

 the fhip by means of a wrinkled leather-like 

 tube, made of a fpongy fubftance, which is 

 tough and blueifh, and has ten or more 

 wrinkles : its ihell is of the Upas kind, bi- 

 valve k , oval, compreffed, water coloured,

 Natura, afcribes to the Upas anatifera five, fmooth, com- 

 preffed valves. F.
