head. These animals are terrestrial, and live under stones in hilly places. lulu* ovalis, Linn, j 

 C/omeris maryinata, Leach. 

 [Fam. 2. — Iulid*, Westw., or the Anguiformes of Latr., Court.] 



lulus proper, Linn., has the body cylindric and very long ; they roll themselves up spirally, without 

 any prominent edge or rim at the sides of the segments. The larger species live on the ground, par- 

 ticularly in sandy places and woods, and emit a disagreeable scent. The smaller ones feed upon fruits 

 and the leaves and roots of esculent vegetables; others are found under the bark of trees, in moss,&c. 

 / minimus, Linn., a native of South America, reaches seven inches in length. lulus tabvlotut, I. inn. 

 (feuciatut, DeGeer), about sixteen lines long, blackish-brown, with two reddish lines down the back ; 

 body with fifty-tour segments, the penultimate pointed, — Europe; and other species described b\ Sal i 

 and Leach (Zool. Misc.) 

 Polydesmus, Latr., resembles lulus in its linear form and habit of rolling itself in a coil, but the 

 segments are compressed at the sides beneath, with a produced margin. Found under stones in damp places. 

 J. eomplanatus, Fabr., and others. 



The species with distinct eyes form Leach's genus Craspedosoma, and appear to be proper to F,ngland, not having 

 been noticed by any prior author. 



[Fam. 3.— Pollyxk.mu.k, Westw., or the PeniciUata of Latr., Cour8.~]—PoUy.renus, Latr.— Has the body mem- 

 branous, very soft, and terminated by pencils of small scales. The antennae are of equal thickness throughout. 

 Scot, layura, Lin., very minute : it has twelve pairs of legs, placed on the same number of semisegments. Found 

 in crevices of walls and under old bark. 



[Dr. Leach has given an excellent monograph of the Rritish species of this family or order, in the third volume 

 of the Zoological Mitcellany, illustrated by figures. M. lirandt has more recently given a distribution of the tribe, 

 in the Bulletin Soe. Jmjier. Natiiralittes </<■ Moscou, torn vi., Is33, dividing them into three sections, — a, Penta- 

 tonia (a, Glomeridea, genus Glomeris, 11 species; b, Sphaerotheria, gen. Sphaerotherium, 5 species; and 

 Sphsropiius, 2 species); b, Trizonia. in. Julidea, gen. lulus, 13 species; and Spirobolus, 2 species; b, Spiro- 

 streptidea (gen. Spirostreptus, 2 species; Spiropaeus, 1 species; Spirocyclistus, 1 species); 3, Monotonia (gen. 

 Strongylosoma, 1 species; Craspedosoma, 2 species; Polydesmus, 6 species ; also, probably, Pollyxenus, Latr, 

 and Callipus, Kisso). Gray, in Griffith's translation of the Riffne Animal; I'erty, in the Delectus Animal. Articul. 

 Brasilia:, and Gucrin, in tin' leonographie Of the Riant Animal, have added various other species or genera. 

 Rafinescjue also described numerous other genera, which have been entirely neglected by systematists.] 



THE SECOND FAMILY OF THE MYRIAPODA,— 

 Chilopoda, Latr. (or the genus Scolopendra, Lin.), — 



Which has the antennae more slender towards the extremity, of at least fourteen joints or more, a 

 mouth composed of two mandibles furnished with a small palpiform appendage, exhibiting, in the 

 middle, the appearance of a soldered articulation, and terminated like a spoon, with toothed edges ; a 

 quadrifid lip*, of which the two lateral divisions are the largest, annulated transversely, resembling the 

 membranous feet of Caterpillars ; two palpi, or small feet, united together at the base, ami hooked at 

 the tip ; and a second lipt, formed by a second pair of legs, dilated and united at the base, and termi- 

 nated by a strong hook, moveable, and pierced beneath the extremity with a canal for the discharge 

 of a venomous liquid. 



The body is depressed and membranous ; each of its rings is covered with a coriaceous or cartila- 

 ginous plate, and only bears, in general, a single pair of feett. the last of which is directed backwards, 

 and prolonged like a tail. The organs of respiration are composed entirely, or in part, of tubular 

 tracheae. 



These animals run quickly ; they are carnivorous, shun the light, and hide themselves beneath stones, 

 logs of wood, the bark of trees, in the earth, &C. The inhabitants of hot climates dread them greatly, 

 the species inhabiting those regions being very large, and their poison much more powerful. 

 Scolopendra morsitans is called, in the Antilles, the Malfaisante. Some of them exhibit a luminous 

 property. 



The spiracles arc more like those of Insects than those of the preceding family, and are cither 

 lateral or dorsal. 



This family (in the arrangement of Dr. Leach composing the order Syngnatha) may, from the last- 

 mentioned characten and the nature of its respiratory and locomotive organs, be thus divided. Some
