Mr. Newport on the Class Mynapoda, Order Chilopoda. 385 



short, with the apex small and bifid. Preanal scale smooth, subcordate, with the mar- 

 gin rounded. 



On examining the few specimens of this genus in the Banksian cabinet 

 belonging to the Linnean Society, I found this species had been ticketed by 

 Fabricius himself as the S. morsitans of Linnaeus. But I have not a doubt 

 that both Fabricius and Linnaeus included several species of nearly the same 

 size under the common name of S. morsitans. Linnaeus, in his own copy of 

 the 'Systema Naturae,' edit. 1766, refers to descriptions of species in numerous 

 works, which prove this to have been the case. Thus, amongst others, he 

 refers to Brown's 'Jamaica' and Catesby's ' Carolina,' and he says of S. mor- 

 sitans, "Habitat in Indiis," and in his 'Systema Naturae' he has also written 

 against it, "Cap. B. Spei." This sufficiently proves that several species have 

 been confounded under one name, and also that the species named by Fabri- 

 cius in the Banksian cabinet was one of those which Linnaeus erroneously re- 

 garded as identical with the true S, morsitans. I was not aware of these cir- 

 cumstances at the time of publishing in the 'Annals and Magazine of Natural 

 History' my description of species in the British Museum cabinets, and on the 

 authority of the Fabrician species in the Banksian cabinet, I then erroneously 

 attached the name of S. morsitans to this African species.

The head and body of this species are light olive, with the antennae 20-jointed, dark green ; 

 legs yellow, with the metatarsi green ; margins of the segments dark green. The den- 

 tal plates are small, slightly elongated, quadrate, with eight small obtuse teeth. The 

 posterior pair of legs are narrow, flattened, and without distinct margins ; the femoral 

 and tibial joints of equal length, with six spinulae on the superior internal border of the 

 femur arranged in two alternating series, four in the upper and two in the lower, the 

 apical one elongated and trifid. The inferior surface of the joint rounded, with from 

 nine to eleven spinulaj, in three elevated series. Lateral anal appendages slightly 

 elongated, quinquefid. Preanal scale short, subquadrate, with the posterior border 

 straight.
