Hub. In Brasilia, {v. in Mus. Brit, et D. Hope.) 



Cephalic segment cordate ; basilar segment large ; mandibular tooth large, with a minute 

 tubercle near its apex; labium smooth, sutures distinct; dental plates large, thick, 

 punctured, subquadrate, a little elongated posteriorly ; teeth eight, black, small, obtuse, 

 with the three internal ones on each side approximated ; posterior pair of legs short, 

 with the basilar joint thick, and subconvex on its superior and external surface, with 

 six or seven spinulae arranged irregularly on the internal margin and superior surface, 

 -■ the posterior or apical one large and acute. Internal surface flattened, with one sharp 

 spine ; inferior surface with five or six small spines arranged in three longitudinal, alter- 

 nating series, two in each series. Lateral anal appendages red, short, with the apex 

 bifid or subacute. Preanal scale four-sided, elongate, with the posterior margin straight. 



This is a very marked and beautiful species, but is subject to much varia- 

 tion in regard to colour. It very much resembles S. variegata, but differs 

 from it in the legs being much thicker, and in the spines on their upper 

 surface being irregularly distributed, as well as in the absence of annulations 

 on the legs ; the spines on the legs also vary in number. 



There are three specimens in Mr. Hope's cabinet, and two in the cabinets 

 of the British Museum.

Cephalic segment large, cordate ; mandibular tooth large ; labium convex, sutures distinct ; 

 dental plates large, quadrate ; teeth six, small, obtuse ; posterior pair of legs short and 

 strong, with the superior surface of the basilar joint plano-convex ; margins rounded. 

 Internal superior surface and margin with five slightly curved spines, the two posterior 

 of which are subapproximated longitudinally, the third placed on the middle of the 

 internal surface, the fourth, very minute, on the superior surface, and the fifth or angu- 

 lar one much elongated, bifid or trifid. Inferior surface convex, with seven small spines 

 arranged in three longitudinal series, two in the external and internal, and three in the 

 middle series. Lateral anal appendages ferruginous, obtuse, with the apex pointed, and 

 the posterior margin compressed and acute. Preanal scale quadrate, elongate, a little 

 narrowed posteriorly, with the posterior margin slightly rounded.
