every direction, strongly reminds me of the spider monkeys 
of South America. One needs little systematic knowledge 
to see that they are highly predatory. Strange, spectre-like 
creatures they are, or rather skeleton-like, with long, slender 
bodies, composed of few joints, and wide sprawling limbs 
set at remote distances — and such limbs ! Two pairs of 
stout antennse, bristled with stiff spines, project from the 
head ; then the first and second pairs of legs, but especially 
the latter, have the last joint but one developed to a great 
size, while the terminal joint is so formed as to shut down 
upon it, just as the blade of a clasp-knife does upon the 
handle. Then, to add to the eflficiencv of this instrument of 
prehension, the great joint which represents the haft is 
armed with a double row of spines set at an angle, so as to 
make a groove, into which the blade falls, and this latter is 
cut along each side of its edge into fine teeth, like those of 
a file. I find several species, even on the same small frag- 
ment of weed if it be tolerably well peopled with Plumu- 
larice or Pedlcettince , some much larger than others, and 
beautifully mottled with transparent ruby-colour on a clear 
horn ; and there is a species larger still, of a dull purplish- 
red hue. But all have pretty much the same manners, ex- 
cept that the smaller species are more agile. These manners
