Tibia ii. has two spines in a longitudinal row beneath, one 

 spine on the outer apical margin, and two on the inner apical 

 margin beneath. Tibiae and protarsi iii. and iv. are numerously 

 spinose. 



The scopula, in the present example, is more or less divided 

 beneath the tarsi of all four pairs of legs. This points to the 

 probability that the example is immature ; probably only those of 

 iii. and iv. are divided in the adult. 



This species is obviously closely allied to M. Simon's type of 

 the genus, S. ravidus E. S., but the difference in the spinulation of 

 t he tibiae of the first two pairs of legs cannot be ignored. It is to 

 be hoped that we shall soon have an opportunity of examining the 

 males of this handsome Spider, which probably occurs under the 

 bark of trees and in holes in the branches (c/. E. Simon). 



A single female, scarcely adult, was taken by Mr. J. H. Hart, 

 and another, still less mature, was sent by Dr. W. Ince, both 

 from Trinidad.

Femur iv. without scopuliform pad on the inner side. Legs 

 not spinose ; fringes on each side, especially the tibiae and 

 protarsi, with long silky hairs, longer than the diameter of the 

 segments in the male, shorter in the female. Ocular area much 

 longer than broad, nearly three times ; anterior row of eyes 

 distinctly procurved. Coxae of pedipalp furnished with a highly 

 specialized lyra, which, together with a corresponding pecten on 

 the base of the mandible beneatli, forms an organ of stridulation. 

 Tibia i. with a pair of simple slightly curved spurs at the apex 

 beneath, in the male sex only.

 $ . Carapace 20 x 17'5 mm. ; mandibles 8-5 ; ocular eminence 4 x 

 1-75. Legs: i. 77— ii. 68-5— iii. 60— iv. 70. 



6 . Carapace 17 X 15-5 mm. ; mandibles 7. Legs : i. 80 — ii. 75 — 

 iii. 62— iv. 75. 



2 . Colour. Carapace black, entirely clothed with olive-green or 

 ochre-grey pubescence. Margins fringed with shaggy hair. 

 Mandibles clothed at the base above with oclire-grey hairs passing 

 into black towards the apex. Outer side clothed with a pad of 

 short black hairs, fading away below. The margins of the fang- 

 groove and mouth-parts clothed with fiery red hairs. The legs are 

 all clothed with short ochre-grey hairs and olive-grey longer hairs, 

 chiefly noticeable on the sides, where they assume, on the tibife, 

 protarsi, and tarsi especially, the form of a plumose fringe. The
