but as it appears to have been taken from a single species, (the Scol. co- 

 leopfrata of Linnaeus), and is so minute, I have selected such parts as 

 more especiall}' elucidate the species, of which his essential characters are 

 the following — " 14 paires de pattes ; corps jaune roussatre, avec trois 

 " lignes d'uu noir bleu^tre le long du dos, et des fascies de la meme cou- 

 " leur sur les cuisses." In the " Genera Crustac," &c. Vol. I, p. 77, 

 published subsequently to the Histoire, he says, " Pedibus triginta ; cor- 

 " pore rufo-flavescente, lineis longitudinalibus pedumque fasciis coeru- 

 " leo-nigris :" and whoever compares these descriptions with Fig. a, 

 will at once, I think, agree that ours is the Scut, araneozdes of Latreille. 

 The following is the list of synonyms in the " Genera:" " Scutigere 

 " araneoide Lot., Hist. Vol. FIT, p. 88. — Scolopendra coleoptrata, 

 " Linn., Sjfst. J^at. ed. 13, Vol. I, pars 2,pag. 3015. — La Scolopendre 

 " a 28 pattes, Geoff., Hist, des insect. Vol. II, p. 675. — Julus araneo'i- 

 " des. Pall., Spic. Zool.fasc. 9, tab. 4, Jig. 16. — Scolopendra coleop- 

 " trata. Fab., Entom. Syst. Vol. II, p. 389, and Panz., Faun, insect. 

 " Germ. fasc. 50, Jig. 12." The synonyms given by Lamarck (Ani- 

 maux sans Vertebres, Vol. V, p. 29,) of his Scut, longipes, are, Scolo- 

 pendre a 28 pattes, Geoff., Vol. II, p. 675, No. 2, and Julus araneoi- 

 des ? Pall., Spic. Zool. 9, p. 85, t. 4, f. 16: and of his Scut, coleop- 

 trata, Scolopendra coleoptrata, Panz., fuse. 50, t. 12, clearly identifying 

 his two species with Latreille's araneo'ides. Dr. Leach's essential cha- 

 racters are, " Corpore livido ; pedibus luteis :" " few, and far between," 

 it is true, but sufficient when backed by the habitat, to leave no doubt as 

 to its being our Fig. b. " Corpore flavescente, glauco ; dorso lineis 

 " tribus longitudinalibus purpureo-nigris, una centrali, duabus lateralibus 

 " e maculis constantibus ; antennis croceis, pallidis ; pedibus flavescenti- 

 " glaucis, violascenti annulatis; oculis atris," are the very words in 

 which I should have thought that I had happily described our Fig. a. They 

 are Risso's description of his Cerm. variegata. I should perhaps have 

 added, incisuris (scutellorum marginibus) pallidis; but as Dr. Leach has 

 not noticed them in his description, although they are shewn in the figure, 

 and as Latreille only says in the generic characters, " les bords semblent 

 " representer une espece de stigmate," I conclude, either that Risso 

 overlooked them in his species, or considered them of no consequence ; 

 that they really arc immaterial, or that they are strictly generic marks.
