Colour, g. Carapace orange, cephalic area dark brown or black, with a band of white hairs behind.

Abdomen black; anterior portion white, followed by black, constriction white above; posterior portion 
black, with seyeral transverse bars of white hairs; spinners yellow, posterior pair often dusky. 
Mandibles orange-brown ; femur of palpus orange; patella, tibia, and tarsus orange-brown. Legs 
variegated, yellow or orange and black. Femora iii. and iv. black; i. and i, yellow, with a dusky 
stripe on each side. Tibia and protarsus iv. dark brown or black ; tarsus i. black. Coxse and trochanters 
i. and ii. yellow; iii. and iv. yellow, with brown side-mottlings. Sternum black. Labium and maxille 
black, apex of the former and inner margins of the latter orange. 
Much paler than the male, dull white and dusky brown. 
Structure, 3. Abdomen much constricted in front of the middle (of the female only slightly so). Mandibles 
The 
very stout, about two-thirds the length of the carapace, almost horizontal, having at the base on the 
upper margin of the fang-groove a long stout tooth, followed by three much shorter teeth, and on 
the lower margin three short teeth closely situated together. The large tooth and the next to it on the 
upper margin are widely separate. Mandibles long and sinuous, with a stout spur at the base of their 
anterior third sectjon. beneath (those of the female are short and vertical). Palpus very long, longer 
than the carapace. Femur stout and curved; tibia stout, curved, and as long as the femur and patella 
together. Tarsus about equalling half the tibia; bulb globular, with a stout spine curving round its 
anterior circumference. No long spiraloid spine as in 7’. centralis. Tibial spur short, stout, pointed, 
its apex directed downwards. 
vulva of the female consists of four brown circular discs, the anterior pair smaller and much closer 
together. A long dark oblique line runs between the discs on each side, marking where the oviduct 
comes near the surface; behind the anterior pair of discs are two other curving dark lines, indicating 
another loop in the oviduct.

MARTELLA. 
Martella, Peckham, Occas. Papers Nat. Hist. Soc. Wisc. ii. 1, p. 45 (1892). 
Type Martella pottsi, Peckham. Central America. 
Eyes in three rows. Cephalic quadrangle broader than long, not wider behind. Carapace twice longer than 
broad, scarcely narrower behind. Cephalic area occupying about half the carapace, flat above in profile, 
convex behind in the thoracic region. Mandibles vertical. Abdomen pediculate; not constricted in the 
middle. Spinners of equal length, anterior pair the stoutest. Palpi of female enlarged in the two 
terminal segments and clothed with long, bristly, fringing hairs. Legs i. and ii. not incrassate ; tibia i. 
with 2—2—2 spines beneath ; protarsus i. with 2—2 spines beneath ; trochanter iv. quite two-thirds as 
long as coxa iv.; coxa i. not longer than coxa iv. Sternum scarcely more than twice longer than broad. 
Small dorsal eyes nearer to the posterior than to the anterior laterals.

I do not know this species in nature and can therefore only compare the figures of 
the vulva with the corresponding portion of M. lineattpes.
