Above the whole, and quite encompassing it, was woven a large tent several times the size of the first tube, and composed of spinningwork whose threads were quite closely placed, but of so thin tissue that one could see through it without any difficulty. A large opening appeared at one end of this external tent, but whether it was left of purpose for a door, or, more probably, was the result of acci- dent, I could not determine. Among the Drassids which I have found in Colorado is a species of Gnaphosa, which I took under a stone on the summit of the Snowy Range. It was dwelling in a little tubular nest. This species, according to Emerton,! is found all over New England, from the White Mountains to New Haven. Professor Packard found a female with a cocoon of eggs on Gray's Peak, Colorado, over eleven thousand feet fHllMlkaljiiii ''' '''''''l#''''''''W,|),)(| Gna- phosa J'lr;, 116.

The cocoon is white and flat, with its diameter as great as, or greater than, the length of the spider. Emerton says that the female stays near her cocoon, but makes no nest. I would have expected her to make her cocoon within her cell. Some of the Drassids, like the Agalenads, protect their cocoons by com- pletely enclosing them in cases of mortar. Among these is a species sent me for determination by Mr. F. M. Webster, assistant entomolo- gist of the State of Illinois, through intelligent interest P the remarkable facts concerning this spider have thus been made known. Mr.
