712 A N I M A 
globutfera , was found in a ditch where tire lemna minor 
grew: the body is round) very pellucid, without mole¬ 
cules, and every where fet with fhort hairs. 14. The 
pnftulata , is found in rnarlhy waters; and is w hite, gela¬ 
tinous, and fomewhat granulated; the lower part trunca¬ 
ted as if an oblique feCtion were made in an egg near the 
bottom. 15. The turbinata, is found in (linking fait wa¬ 
ter; and is round, pellucid, fomewhat of the (hape of an 
acorn, with a pellucid globule at the low er end. 16. The 
acuta , is found in (alt water, and is gelatinous, thick, ca¬ 
pable of alfuming different fltapes; having the apex bright, 
and the reft of the body filled with little fphertiles. 17.

fomewhat of a kidney-fhape, but ventricofe. 23. The 
Jluxa , is reniform and finuated. 24. The aimilla, is round 
and annular. 25. The cornuta, is of the fliape of an in¬ 
verted cone, opaque, and of a green colour; the body is 
compofed of molecular vehicles ; the fore part is wide and 
truncated, with a little prominent horn or hook on both 
fides : at one time this animalcule will appear reniform 
and ciliated on the fore part; but at another time the hairs, 
are concealed: it dilfolves into molecular vehicles when 
the water evaporates. 26. The heteroclita, appears to the 
naked eye like a white point; in the microfcope as a cylin¬ 
drical body; and wholly ciliated through a large magnifier. 
XIII. Trichoda: an invifible, pellucid, hairy worm. 
1. The grandinella, is a very fmall pellucid globule, with 
the inteftines fcarcely vifible, the top of the furface furnifh-

is found in falt-water: it is fmooth and free from hairs, 
except at the fore part, where there are a few. 6. The 
Jo/, is fmall, globular, and cryftalline ; befet every where 
with diverging rays longer than the diameter of the body : 
it was found with other animalcules in water which had 
been kept three weeks. 7. The folaris, is orbicular, bright, 
and filled with globular inteftines, frequently having in it 
a moveable fubftance of the flrape of the letter S. 8. The 
bomba , is of a yellow colour, and full of clay-like mole¬ 
cules : it moves with fuch velocity as to elude the fight, 
and appears of various ftiapes, fometimes fpherical, fome-

veficular molecules ; is of a fpherical figure, fmooth, pel¬ 
lucid, and a little notched in the fore part. 10. The ur- 
nula, is membranaceous, pellucid, fomewhat in the form 
of a water-pitcher, with the fore part hairy: it moves but 
(lowly. 11. The diota, is of a clay-colour, and filled

narrow in the fore part, and refembling an inverted club. 
17. The nigra, was found in fait water, and lias an opaque 
L C U L E. 
body; but when at reft one fide appears pellucid : when 
in violent motion, it feems entirely black. 18. The pubes, 
is found in water where duckweed grows, chiefly in De¬ 
cember : the apex is furnifhed with hairs, but they are 
feldom vifible till the creature is in the agonies of death, 
when it extends and moves them vehemently, attempting' 
as it were to draw in the very laft droji of water. 19. The 
Jloccus, is membranaceous, the fore part rather conical, 
with three fmall hairy papillae projecting from the bale. 
20. The finuata, is found in river water : it is oblong and 
deprefted, with one margin hollow and hairy, and the 
lower end obtufe; it is of a yellow colour. 21! The 
praetps, is pellucid, the forepart formed into, a kind of 1 
neck; one edge riling into a protuberance like a hump¬ 
back, the other edge convex. 22. The protcus, is found 
in the (limy matter adhering to the (ides of veflels in which 
vegetables have been infufed, or animal fubftances pre- 
ferved : the body of this animalcule refembles that of a 
fnail. 23. The verfatilis, lives in the fea, and has fome 
refemblance to the proteus; but the neck is (horter, the 
apex lefs fpherical, and the hinder part of the trunk acute. 
24. The gibba, is pellucid; the upper part fwelled out, 
with numerous molecules, and three large globules on the 
infide. When the water begins to fail, a few minute hairs 
may be difeovered about the head, and at the abdomen. 
25. The foeta, fomewhat refembles a rolling-pin in fhape ; 
has both ends obtufe, and one flior er than the other : it 
can draw in the ends, and fvvell out fo as to appear almoft 
fpherical. 26. The patens, is found in fait water; and is 
of a long cylindrical (hape, filled with molecules, the fore 
part bright and clear, and is befet with hairs. 27. The 
patula, is ventricofe, rather inclining to an oval figure, 
with a fmall tube at the fore part, the upper part of which 
is hairy. 28. The feveata, is oblong, and broad, with 
three little horns on the fore part. 29. The Jiriata, is found 
in December, in river water : it is a beautiful animalcule,

fhort hairs. 31. The aurantia, is of a gold colour, pel¬ 
lucid, and filled with veficles. 32. The igniti , is of a 
fine purple colour, with fomething of a reddifti caft, pel¬ 
lucid, (plendid, with a number of globules of different 
fizes. 33. The prifma, is very fmall, and fo tranfparent 
that it cannot eafily be delineated : it is of a Angular (hape ; 
the under part being convex, and the upper compreffed 
into a kind of keel. 34. The forceps, is found about the 
winter folftice in water covered with lemna : it is of a yel¬ 
low colour, large, fomewhat tranfparent, and filled with 
molecules, with a large opaque globule in the lower part. 
35. The forfex, is found in river water: it has the fore 
part formed into a kind of forceps, one of which is twice 
as long as the other, hooked and ciliated. 36. The index, 
is found in fait water, and has the under part of the front 
of the margin hairy; the apex is formed by the fore part 
projecting like a finger on a direction poft. 17. The tri- 
choda, is of a yellow colour, formed of two pellucid mem¬ 
branes ftriated longitudinally ; the lower end obliquely 
truncated, and the two extremities bent in oppofite direc¬ 
tions. 38. The navicula, has three corners; the fore part 
truncated and ciliated, and a kind of longitudinal keel 
runs down the middle. 39. The J'uccifa, is of a flattened 
oval (hape, the edge hairy, and hollowed out in (rich a 
manner as to form two unequal legs. 40. The fulcata, 
is ovated and ventricofe, the apex acute, with a furrow 
at the abdomen, and both (ides of it ciliated. 41. The 
anas, is found in pure water, and is fmooth, five times 
broader than it is long, filled with darkifti molecules. 42. 
The barbata, is round, fomewhat linear, with both ends 
obtufe ; the fore part narrower, forming as it were a kind 
of neck, under which is a row of fluctuating hairs. 43. 
The farcimen, is long, round, pellucid, and covered with 
very minute hairs, and has a great number of mucous ve¬ 
ficles about the body. 44. The crinita, is long, round,
