appear composed of very numerous and crowded fibres, dis- 
posed on a single plane, one against the other. The anus is 
situated at the inferior root of the stylet, terminating the body. 
According to an observation which has been communicated 
to us by M. Straus, the interior of the first buckler presents, 
besides the brain, but a single ganglion, the sub-oesophageal. 
The two nervous cords are afterwards lengthened into the 
interior of the second buckler, and form there at the origin of 
the branchial feet, but faintly marked ganglions, which throw 
out branches over those organs. According to M. Cuvier, 
the heart, as in the stomapoda, is a thick vessel, furnished 
internally with fleshy columns, running along the back, and 
giving off branches on both sides. A rugose oesophagus, 
ascending forwards, conducts into a very fleshy gizzard, fur- 
nished internally with a cartilaginous coat, all bristled with 
tubercles, and followed by a w’ide and straight intestine. 
The liver pours the bile into the intestine by two canals on 
each side. A great portion of the testa is filled by the ovaries 
in the female, and by the testicles in the male. 
These Crustacea sometimes attain to the length of two feet ; 
they inhabit the seas of warm climates, and are found most 
frequently on their shores. It appears to me that they are 
peculiar to the East Indies, and to the coasts of America. 
Here we designate the species found there ( Limulus cyclops ), 
pan , or sauce- pan-Jish, because it has something of a 
similar form to this article, and by removing the feet, the 
testa may serve to draw water. According to the testimony 
of M. Leconte, a most accomplished naturalist, and who has 
so greatly contributed by his researches and discoveries to the 
progress of entomology, it is given to pigs to eat. The savages 
employ the stylet of the tail to make arrows; the point is 
considered formidable ; their eggs are eaten in China. When 
these animals walk, their feet are not visible. They are found 
in a fossil state in certain strata of a middle formation.
