This animal is common in the Eaft Indian, 
fome parts of the American feas. 
Nautilus, Paper. This fpecies receives it's 
name from the thinnefs of the fliell, which is 
about the confiftence of ftrong paper or parch- 
ment; and is often twelve inches long, compreffed 
on both fides. The opening of the mouth is 
very long and narrow, and there are no ears ; 
but the angles of the hinder part of the mouth, 
between which the fpiral turn of the ihell enters 
the cavity, are high and fliarp. The whole ex- 
ternal furface is beautifully variegated with un- 
dulated lines, and hollow fpaces between them; 
and a furrow runs all along the back, on each 
fde of which the ridges are fliarp and ferrated. 
Nautilus, Thin, Earless. This fpecies is 
but five inches long, and three or four deep ; the 
aperture of the mouth is very long and narrow; 
the fliell is very thin and delicate; and the colour

There are eleven fpecies, feveral of which are 
found in the Britifh ieas. 
Nereis, Bright. This fpecies illuminates 
the fea after the manner of glow-worms, hut 
with a much brighter luftre. Sometimes, by their 
means, the whole liquid element fecms to be ia 
aglow during the night; and, in rowing, it is 
not uncommon to fee every oar fpangled with 
them, while the water flames with more than 
ufual brightnefs. Thefe creatures, however, are 
too minute to admit of a particular examination; 
for it is the affemblage of myriads of them that 
affords the nofturnal blaze. 
Nereis, Bog. This fpecies, which inhabits 
moift fituations, has a linear, jointed body, with 
a filiform foot ilfuing from each joint. The 
whole animal is fcarcely larger than tlie Ihort 
briftle of a hog; and it's peculiar conformation 
can only be feen by the alTiftance of tlie mi- 
crofcope.

in the deep, is fmooth, depreifed, and ccmpofed 
of a vaft number of fegments of a blueifii green

the Sabella, has a flat body, attenuated towards 
the tail, and pellucid; on each fide there are thir- 
teen feet; and about the mouth there is a feries 
of very fine filaments. 
Nereis, Red. This fpecies has a flender de- 
preffed body; two black Ipots on the front; is 
attenuated at the extremity, when the forceps is 
withdrawn; and has a deep and longitudinal line 
along the middle of the back. The length is
