or any other Juice proper for its Nourifliment. In 
fine, when this little Animal defires to change its 
Place, it makes ufe of its Protuberance and its Pump, 
which is the little Hollow under its Head, and feems 
to ferve it for a Mouth : It applies this Part to the Place 
D, whither it would remove its Body, and after be- 
ing prolonged by it*s fore Part to reach the Place, where 
this Application (hould be made, it draws its Protu- 
berance and pump together, by bending its fore Part 
circularly, after the Manner of fome C<nt eTptll^fs , 
Its Protuberance being applied, it loofens its Pump, 
and prolonging itfelf, applies it to another Place more 
forward : The Pump being faftened, it bends itfelf cir- 
cularly again to bring the Protuberance up to it, and 
apply it as before. By this we fee that the Worm pro- 
longs itfelf to apply its Pump, and contrads itfelf to 
do the fame with it’s Protuberance. Thus thefe Mo- 
tions and Applications are made fucceflively, and as 
often as there is Occafion. The hinder Part fallens it- 
felf to nothing, but is always drawn by the Part which 
goes before it. i r 
I found this Worm in the empty Stomach of aFilh, 
called by the Portugueze^ Bonite : It was faftened by 
its Protuberance upon one of the Folds of the inner 
Membrane of this PtJ'cus, This little Le^ich made a 
pretty deal of Refiftance when one endeavoured to 
pluck it away. . 
I ftiall add to this Defcription fome Reflexions and 
Conjedlures, formed on the Phenomena which I have 
obferved in this Infed. I have obferved, i. That this 
little Animal did not live above two Hours after it was 
taken out of the Place where I found it. That- it
