380 Mr. J. Blackwall on newly discovered Spiders 
spots, are disposed on the anterior part of the cephaiothorax in 
two transverse rows; the four intermediate ones form a trape- 
zoid whose anterior side is the shortest, those of the anterior 
pair are placed on a small tubercle, and those of the posterior 
pair, which are much the largest of the eight, are placed on se- 
parate tubercles ; the eyes of each lateral pair are the smallest, 
- and are seated near to each other, but not in contact, on a mi- 
nute tubercle. The cephalothorax is moderately convex, glossy, 
compressed before, rounded in front and on the sides, which are 
marked with slight furrows converging towards an indentation 
in the medial line; it is of a dull-yellow colour, with a brownish- 
black Jongitudinal band in the middle, and a less distinetly de- 
fined one of the same hue above each lateral margin. The falces 
are long, conical, rather divergent at the extremity, armed with ° 
teeth on the inner surface, and inclined towards the sternum ; 
and the maxille are straight and enlarged and somewhat rounded 
at the extremity. These organs have a dull-yellow colour, faintly 
tinged with brown. The lip is nearly semicircular, but pointed 
and prominent at the apex; and the sternum is heart-shaped. 
These parts have a reddish-brown hue, the lip beg much the 
darkest. The legs are long, very slender, provided with hairs 
and a few spines, and are of a dull-yellow hue, with brown-black 
annuli at the extremity of the foints; the first pair is the longest, 
then the second, and the third pair is the shortest ; the tarsi are 
terminated by claws of the usual number and structure. The 
palpi are short, paler than the legs, and without brown-black an- 
nuli; the radial is larger than the cubital joint, and has a long 
bristle at its extremity, in front; the digital joint is oval, convex 
and hairy externally, concave within, comprising the palpal or- 
gans, which are moderately developed, rather complex in struc- 
ture, with a long, prominent, dark-brown, filiform spine, that 
originates near their extremity on the inner side, and curves 
obliquely upwards to the outer side; these organs have a brown- 
ish-red hue. The convex sides of the digital joints are directed 
towards each other. The abdomen is long, subcylindrical, or 
somewhat depressed, and projects a little over the base of the 
eephalothorax ; it is glossy, of a pale dull-yellowish colour, and 
has a black band extending along the middle of the, upper part 
about two-thirds of its length; this band, which has numcrous 
white spots on each side of it, 1s bifid at its posterior extremity, 
and is succeeded by several angular lines of the same hue, whose 
vertices are directed forwards; and a black line, slightly varying 
in breadth, passes along the upper part of each side, the two 
meeting above the spinners; a broad, dark-brown, longitudinal 
band occurs in the middle of the under part, and the colour of 
the branchial opercula is pale yellow.
