42 Dr. Heineken on Cer matin. 



with the figure (which I suspect to be far from an accurate one) at least 

 as well as that description did, I felt perfectly satisfied ; and although Dr. 

 Leach hinted a suspicion that his Cerm. livida and the Scolopendra cole-- 

 optrata of Linnaeus might be the same, yet as he appeared unable to de- 

 termine the matter, I thought it by no means probable that I should suc- 

 ceed, and therefore took the negative for granted. Happening, however, 

 a short time since to meet with a new species in Risso's " Histoire Natu- 

 " relle," &c. Vol. V. p. 153, which he had named Cermatia variegata, 

 and finding that ours answered to its description, I was led to prosecute 

 the inquiry ; and the result is, (as T hope to prove,) that the Scolopendra 

 coleoptrata of Linnaeus, — the Scutigera longipes and coleoptrata of 

 Lamarck, — the Scat, araneoides of Latreille, — the Cermatia livida of 

 Leach, and the Cerm. variegata of Risso, are one and the same, and 

 identical with ours. 



As I have not any of the works referred to by Lamarck and Latreille, 

 I am obliged to adopt one of their species as a standard, and by identify- 

 ing ours with that species, to assume its correspondence with the syno- 

 nyms. I shall take Latreille's Scut, araneoides. 



In his "Histoire Naturelle," &c. Vol. VH, p. 86, &c. he says, " Les 

 " palpes maxillaires sont longs et epineux" — " le corps a, outre les pe- 

 " tits anneaux dont je viens de parler, sept autres recouverts chacun en 

 " dessus d'une plaque bien terminee dans les contours, comme un petit 

 " bouclier, presque carree, avec le bord posterieur arrondi aux angles, 

 " echancre au milieu, et ayant dans ce sinus une petite fissure, dont les 

 ** bords etantun pen releves semblent representer une esp^ce de stigmate," 

 &c. &c. &c. — " Les trois premieres plaques, a coromencer par la tete, 

 " sont un peu plus courtes et la quatrieme est la plus longue. Linneeus 

 ** et Pallas en comptent huit. Je crois que la huitieme doit fetre censee 

 " faire partie de I'espece de petite queue qui resulte des segments termi- 

 " naux sans pattes." — " Les pattes sont beaucoup plus longues que dans 

 " ces insectes (les Scolopendres) et par la figure de leurs articles se rap- 

 " prochent de celles des Faucheurs, &c. &c. Les six dernieres paires, et 

 " surtout les terminales, sont plus longues que les huit premieres, &c. 

 " Les tarses sont fort longs, composes d'une infinite d'articles se roulanl 

 " sur eux-memes a leur extreraite," &c. &c. — " On trouve la S. arane- 

 " oi'de dans les maisons." — This I am aware is his generic description.
