sub-order Teirapneiimones, but the fact that it spins a web Hke a Tubi- 

 Jelaria excludes it from the Terri/elan'ce and demands at least a new 

 family. 



I have named this interesting spider, at the suggestion of Prof. 

 Thorell, Hypochihis, and, in appreciation of this distinguished naturalist, 

 Hypochihis thorcUii, and the new famil}- I have called Hypochilidcc.
