is found in Australia and the Malay Archipelago), while it 

 bulges out in front, like Farnsenus, has the cephalothorax exces- 

 sively high, square-looking and massive, and has all the eyes 

 much larger in proportion to the size of the spiders. In PJdd- 

 ippus the ej'es are even smaller in proportion to the size of the 

 spiders than in Parnsenus, the widest point of the cephalo- 

 thorax is not in front of the dorsal eyes, and tlie quadrangle of 

 the eyes is plainly wider behind than in front. In Thyene, the 

 spiders run smaller than in Parnmnus, the cephalothorax is dif- 

 ferently shaped, and the lateral eyes of the first row are very 

 small, only half as large as the middle eyes.

The clypeus is very narrow. The fakes in the female are 

 stout and moderately long and have the anterior surface con- 

 vex. In the male they are longer and are directed obliquely 

 forward, with a long fang, while on the inner face is a long, 

 strong tooth. The sternum is long and oval. The maxillae 

 are long, heavy and obtusely rounded. The labium is long 

 and slender and pointed at the extremity. 



In the male the integument of the whole body is very dark, 

 almost black, and three of our four specimens show patches of 

 scales of a most vivid iridescent green color, which, in one case, 

 entirely cover both cephalothorax and abdomen. In these 

 three specimens the falces are of an iridescent bluish green color. 

 In our fourth male the scales that are left on the cephalothorax 

 and abdomen are iridescent red and violet (the green ones 

 probablj' having been all rubbed off), and the falces are brill- 

 iant iridescent red with some greenish reflections. They all
