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, pi. 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 cephalothorax 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, hke tiiose in 

 the genus Epeira.
