6o ARACHNOIDEA, 



CASE passage, the effect of which is, that on looking in at the upper 

 door one only sees a short tube with nothing in it, while the 

 spider is behind the termination, ready to fly up the oblique tube 

 if the door at the bottom should be forced, which would neces- 

 sarily fall back and conceal from view the entrance to the upper 

 tube, leaving to all appearance nothing but a silk-lined tube 

 uniform throughout. 



Nemesia c^mentaria {Latr.). 



This is a rather large yellowish fawn-coloured spider, of which 

 specimens are put in the next case. 



Nemesia csementaria (scarcely mag-nified). Nemesia eleanora (slightly magnified). 



No. 20. Nemesia eleanora {Cavib.).—^^. Diagram of the double-branched nest 

 of, with an outer and inner trap-door, from Mentone, as above described. 



This is a yellowish spider, very similar to Nemesia csementaria. 



Mr. Moggridge describes and figures various kinds of trap-door 

 nests that he observed near Mentone, and no doubt if the rest of 

 the shores of the Mediterranean were equally well searched, a 

 gireater number of species would be found. 



During the last year two or three specimens of a trap-door 

 spider's nest, constructed on another fashion in a peculiar locality, 

 viz. in the bark of a tree, have been received in England from 

 South Africa. The nest and lid are as nearly like the bark it- 

 self, as those from the ground are like the soil where they are 

 made. It would appear from more than one of the same kind
