3. Branch, nuda, caerulescenti-violacea, pedibus flavescentibus ; postremis valde elongatis 

 cylindricis : articulis femoralibus tibialibus tarsabbusque subaequalibus : metatarsabbus 

 compressis: femoribus nudis vel inferne spinula unica minutissima armatis. — Long. 

 unc. If, 



Hab. In Nova Hollandia, ad Paramatta, [v. in Mas. nostr.) 



Cephalic segment subtriangular ; antennae 20-jointed; teeth eight, black, rather small, very 

 acute, the two internal ones on each plate subapproximated ; mandibular tooth very 

 Ifu-ge, with a tubercle at its apex. Labium smooth, polished. Posterior pair of legs 

 naked and cylindrical, with only an extremely small spine on the under surface near 

 the base. Lateral anal appendages short, punctured, with the apex rather obtuse, or 

 slightly bifid. Preanal scale short, subquadrate, with the posterior margin slightly 

 rounded. 



4. Branch, spinicauda (Tab. XL. fig. 7.), pallide brunnea, linea unica dorsali mediana satu- 

 ratiore, pedibus longis ; postremorum articulo basali in margine interiore medio spina 

 unica maxima armato. — Long. unc. 1^*^. 



Scolopendra spinicauda, Newp. I. c. p. 98. 



Hab. In Africa Boreali, prope Tripoli, Ritchie, {v. in Mus. Brit.) 



Cephalic segment cordate, subquadrate, with the posterior margin straight ; antennae 1 7- 

 jointed, large at the base; basilar segment large, narrowed posteriorly; mandibular 

 tooth large, with a small spine at its apex ; labium smooth, with the longitudinal sul- 

 cus distinct; dental plates narrowed, subquadrate, with the posterior external angle 

 elongated ; teeth eight, triangular, acute, with the second and fourth on each plate most 

 projecting from the plane of the teeth; posterior pair of legs elongated, with the basi- 

 lai" joint rather short, and its superior and lateral surfaces rounded and armed on the 

 internal superior margin with one very large spine, and one very minute one at the in- 

 ternal posterior angle. Inferior surface somewhat quadrate, with six sharp spines, 

 arranged in two longitudinal alternating series, three in each series, the external one 

 on the margin, and nearest the base of the joint. Lateral anal appendages roughened, 

 tuberculous, with the apex smooth, elongated and pointed. Preanal scale cordate, sub- 

 quadrate, with the posterior border slightly emarginated. 



This is an interesting and very elegantly formed little species, several spe- 

 cimens of which were sent to the Museum in the same bottle with others of 

 Scolopendra spinigera, of which at first I regarded it as the other sex. It varies 

 in sometimes having four spines in the external inferior series.
