table. It is probable that those trap-door spiders 

 which inhabit nests with short tubes, and which 

 tlierofore can be transported nest and all, would be 

 less disconcerted by imprisonment than is the case 

 Avith other kinds living at the bottom of a long 

 burrow which it is almost impossible to carr^'- away 

 entire. This is borne out by what has been related 

 {Ants and jSjnders, p. 122) of the habits of Cfeniza 

 ionica in captivity, which not only endured to have 

 its nest set upside down in a flower-pot, but actually 

 furnished the inverted base of the tube with a door 

 appropriate to its new position. 



Canon Tristram (the well-known author and na- 

 turalist) was so kind as to send me two trap-door 

 nests from Palestine for inspection ; these were small 

 cork nests, the doors of which resembled those of the 

 Mentonese Cteniza {Ct. Moggridgli), but the tubes 

 were exceedingly short, and that of the more perfect 

 specimen, as I gather from Canon Tristram, measured 

 only two inches and an eighth in length when 

 entire. 



The nests of Cteniza ionica are but little longer, 

 and that of the Mentonese Cteniza, though never so 

 shallow as these, are far less deep than those of 

 Nemesia ccementaria, the builder of the typical cork 

 nest. 



And now we will leave the nests of the cork type 

 and their inhabitants, and turn to the more intricate 

 group of nests belonging to the wafer type. Follow- 

 ing the order indicated in the diagrams, we will begin 

 with the simplest type of all, fig. C, and afterwards 

 take the remaining types one after the other, ad- 

 vancing until we reach the most complex type, G,
