 when seen from beneath. 



Scutigcra, Lamarrk (Cn-ma/ia, Illii^er), forming a g-enns very distinct from the rest of this family, has the body 

 covered by ei;;-ht sliield-like plates, beneath each of which M. i.le Serrcs has observed two i^neuniatic sacs, or vesi- 

 cular tracheje, connnunicating; with tubular, lateral, and inferior trachcT. The under side of the body is diviiied 

 into fifteen semi-segments, each bearing- a pair of legs terminated by a very long, slender, and multiarticulated 

 tarsus; the hind pairs are very lon;^. The eyes are large and facetted. They form the passage from the preceding 

 family to the present, lliey are very active, and often lose some of their legs when touched. The French

 of the wood-work uf houses. S. loii-^/icunii.s, I'abr., and other species. 



Litliobius, Leach, has the spiracles lateral ; the body di- 

 vided, both above and below, into the same number of seg- 

 ments, each of which bears a pair of legs; and the dorsal 

 pli'iti's fin.' .liteinately longer and shorter. 'Scolopendra forci-

 Leach {Zuol. Misccl. vol. iii.) 



The others have at lea^t twenty-one pairs of feet, 

 and the segments are of eijnal i-ize and number, both 

 above and beneath.

southern departments of France, and other countries of the south of Europe, produce a species (Sco/. /M\
