Spider; it is not only very prominent (projecting below the basal 
joints of the legs), but the legs of the 3rd and 4th pairs are set into 
it in such a way as (when looked at in profile particularly) to show 
a portion of it between them and the margins of the thorax. ‘The 
sternum is covered with scales like the abdomen. 
The abdomen is of a pale dull (though somewhat golden) yellow 
hue, the four sharp prominences being rather darker; the pos- 
terior part and sides are marked with curved transverse rows of 
small deep red-brown spots or points. The prominence supporting 
the spinners is dark yellow-brown; and the genital aperture is 
placed in a large deep-red-brown area. The whole abdomen is 
covered with scales (as above noted) and also with very minute 
bristle-like hairs, apparently one to each scale. 
A single example of this remarkable Spider was contained in 
Mr. Traill’s Amazon collection.

The general form and appearance of this Spider is very similar to 
that of the typical species from Ceylon (described and figured 
Journ. Linn. Soc. x. p. 401, pl. xiv.); but its specific characters are 
very strong, and will serve to distinguish it at a glance from all the 
few species of the genus yet described. 
The cephalothoraz is short and of a somewhat pentagonal form, 
much the broadest at the eyes (giving it there an angular appearance), 
and truncate at its posterior extremity. At the base of the falces it 
is rounded ; and just behind the eyes there is a very strong and deep 
transverse indentation. 
The eyes are moderate, and not very unequal in size; they are in 
two pairs widely separated, each pair placed in the angle at the 
widest part of the caput. The eyes of each pair respectively are 
placed on strong black tubercles, and are near to each other, being 
separated by less than two diameters’ interval, and forming a line 
nearly at right angles to the plane of the cephalothorax. 
The legs of the first pair are long and strong, issuing from in 
front on each side just beneath the angle where the eyes are 
situated, and by their strength appearing to have thrust both the 
second pair and the palpi out of their normal places. The fourth 
pair are next in length and strength, but very much less in both 
respects than those of the first pair. The third pair are the 
smallest, being somewhat shorter and weaker than those of the 
second pair. All armature, excepting calamistra on the metatarsi of 
the fourth pair and the terminal tarsal claws, had been rubbed 
off the two examples examined. The tarsal claws are 3 ordinary 
ones with 2 or 3 others, supernumerary and opposed, like those in 
the genus Epeira,
