TRAP-DOOR SPIDERS. 301 



more elevated caput, general dark colour, distinct an- 

 t^ular bars on the abdomen, and almost contiguous 

 lateral eyes, as well as the form of the nest, will 

 readily distinguish it. 



It is with great pleasure that I connect with this 

 spider the name of my most kind friend and brother 

 arachnologist. Monsieur Eugene Simon, to whom I 

 am so greatly indebted for much information and 

 numerous examples of rare spiders. 



I must not conclude these descriptions without 

 expressing my sense of obligation to Mr. Moggridge 

 for so kindly allowing me to add them to the far 

 more pupular, and more interesting, portion of this 

 volume, in which the habits of these spiders are 

 recorded. 



Descriptions of colour, form., and structure are but 

 dry details, though very necessary for the deter- 

 mination of species ; and in the present case it is 

 very important as well as interesting to be able to 

 conclude with some certainty that differences of type 

 in the tubular nests of the spiders Mr. Moggridge 

 has observed so closely and accurately, are joined to 

 well-marked specific differences obtained from those 

 other characters above mentioned, and which it has 

 been my endeavour to detail as fully and faithfully as 

 possible.
