126 ARANEIDEA. 
Carapace convex, scarcely longer than broad. Anterior row of eyes slightly recurved, posterior row slightly 
procurved. Eyes of anterior row equal; centrals just over half a diameter apart, less than a half from 
the laterals. Eyes of posterior row equal, equidistant, one and a quarter diameters apart. Clypeus 
scarcely equal to one diameter of an anterior central eye. 
Palpus: tarsus nearly three times as long as broad. Palpal bulb consisting of one large lobe (the two lobes 
distinguished in S. annulatus being fused) whose apex forms a very strongly curved stylum, its extreme 
apex blunt and notched on the inner side. Tibial apophysis trifid: the upper branch longer, thin, 
ensiform, sinuous, directed upward ; seen from above, elbowed in the middle, its apex directed outward ; 
the middle branch black, curved, spatuliform at its apex; the outer branch stout, with two strong teeth 
or spurs on the lower margin (seen in profile); seen from above its apex is strongly elbowed and directed 
upward. 
Hab. Mexico (Mus. Brit.). 
12. Sparassus annulatus, sp.n. (Tab. IX. figg. 13, 18, a-d, ¢ .) 
Type, ¢, in coll. Godman & Salvin. 
. Total length 8 millim. Carap. 4:25 x 4 millim.. 
d. Carapace, legs, and sternum pale orange. The base of the tibia, a spot towards the apex, the base, some- 
times a spot in the middle, and the apex of the protarsus of all four pairs of legs, black. 
Carapace convex, scarcely longer than broad. Anterior row of eyes slightly recurved, posterior row slightly 
procurved. Eyes of anterior row equal; centrals half a diameter apart, one-quarter a diameter from the 
laterals. Eyes of posterior row equal, almost equidistant, one and a quarter diameters apart. 
Palpus: tarsus three times as long as broad. Palpal bulb consisting of two elongate lobes, with a curved, pale 
process between them at their apex ; the left lobe terminates in a curved stout point, forming a stylum (a). 
Tibial apophysis trifid; its upper branch longer, thin, sinuous, and pointed (b); its middle branch broader, 
shorter, congave, lamelliform, its apex depressed, having also towards its base a thin triangular piece, 
directed outward and downward; its lower or outermost branch, viewed in profile, terminates in a 
depressed point and is itself concave lamelliform in character. 
Hab. Mexico, Rio Papagaio in Guerrero (H. H. Smith). 
A single adult male of this very distinct form was taken by Mr. Smith.

Type of S. ferrugineus, Keys., from Mexico, in coll. Keyserling, in Mus. Brit.; that of O. sagus, O. P.-Cambr., 
from Guatemala, in coll. Godman & Salvin. 
2. Total length 12°6 millim. 
Hab. Mexico, Peak of Orizaba *, Tepic® ; Guaremata, Petexbatum (Sarg *). 
It is unlikely that the specimens from Central America are identical with the 
original Ocypete ferruginea from Brazil; but being unable to see Koch’s type, I leave 
the identity of the species as determined by Keyserling. The figure of the vulva is. 
taken from Keyserling’s type.
