Notes on habitations.*- -The nests of Poecilomigas are invariably 

 furnished with two trap-doors, one at each end of the tube. In one 

 example the rear trap-door is spun over with a disc of silk which is 

 connected by a prominently ridged band with another similar disc of 

 silk fastened 011 to the bark ; the rear door is thus apparently held 

 down, but capable of being used if necessary. In another nest, how- 

 ever, the hinge of the posterior door is but slightly removed from the 

 anterior one their distance apart is usually commensurate with the 

 size of the inhabilant and the two silk discs are fastened one on 

 the side of each of the doors, and are themselves hinge to hinge (as in 

 the above example also) ; in this case the advantage seems so proble- 

 matical that it may be doubtful if the silk discs with their connecting 

 bauds are the work of the spiders to whose habitations they are 

 attached particularly as they are concealed by being covered with 

 grains of earth and sand instead of pieces of bark and lichen. In 

 another nest the doors were widely separated, the posterior one being 

 smaller than the anterior one, and securely fastened down on the 

 inside so as to be useless for escape (see also P. Z. S. 1887, p. 42) ; 

 on this nest and on another similar one there were no traces of the 

 connected discs as above, which further seems to show that they are 

 not the work of the inhabitants of the nests to which they may be 

 attached as above.
