ORDER P(ECILOPODA. 363 



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 wide 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 {himulus cyclops), 

 fan, or sauce- pan-JisJi, 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.
