404 REV. O. P. CAMBRIDGE ON [June I, 
side of the eminence on the caput, as well as the upper part of the 
fore extremity of the caput itself, is clothed with a few short hairs, 
directed forwards and downwards. 
The eyes are small, placed in the usual four pairs, on black spots ; 
those of the upper or hind central pair are placed on the fore side of 
the summit of the cephalic eminence, each being rather more than 
a diameter’s distance from the longitudinal line which divides its two 
lobes from each other; the other three pairs (looked at either in 
front or sideways) form a transverse straight line at the fore ex- 
tremity, on the upperside of the caput, rather exceeding in length 
that formed by each lateral pair and the hind central eye on its side ; 
those of each lateral pair are placed a little obliquely on a-slight tu- 
bercle ; those of the fore central pair are near together (but not. con- 
tiguous to each other) on a tubercle. 
The legs are long and slender, coloured as described above, and 
furnished with hairs, and some fine spines beneath the tibie of the 
first and second pairs; their relative length is 1, 4, 2, 3. 
The palpi are tolerably strong and moderate in length ; the cubital 
joint has some short spine-like bristles on its outer side, it is slightly 
bent downwards, and about double the length of the radial, which has 
its fore extremity on the upperside prominently produced into a 
moderately long tapering apophysis, curved downwards, and its mar- 
gins fringed with hairs; the digital joint is large, and of an irregular 
form, and suffused with brown; it has a strong, prominent, some- 
what keel-like lobe at its base on the outer side, furnished with a 
single row of very short, but strong, closely set, curved, spine-like 
bristles ; the palpal organs are highly developed, prominent, and 
complex ; a large corneous process projects from their extremity, 
and a strong, black, tapering spine issuing from its base curves in a 
circular form backwards on their outer side; in connexion with this 
spine, quite to its point, there is some yellowish diaphanous mem- 
brane; above the spine just noted, at the base of these organs, on 
their outer side, are two other large irregular corneous processes. 
The falces are tolerably strong, but not very long; they are of a 
conical form, directed backwards towards the labium, and furnished 
with a few very minute teeth on the inner margin near their ex- 
tremities. 
The mawille, labium, and sternum are of normal form. 
The abdomen is large, of a roundish oval form, tolerably convex 
above, and of a glossy black colour, the spiracular plates being yel- 
low ; it projects a little over the base of the cephalothorax, and is 
clothed thinly with very short hairs, its surface being thickly 
covered with very minute puncture-like impressions, four of a larger 
size forming on the middle of the upperside a rectangular figure 
whose fore side is shortest. 
The female resembles the male in colours and general characters ; 
but the cephalothorax is devoid of the cephalic eminence, the abdo- 
men is more convex above, and the spines on the tibie (and meta- 
tarsi as well) of the first two pairs of legs are of a more marked cha- 
racter; the palpi have, among other hairs and bristles, a row of
