ON THE ORDEKS 



there is a nondescript genus of Spiders from India, of 

 which the abdomen is as minute, in proportion to the other 

 parts of the body, as in Pycnogonum ; so minute indeed 

 as to have occasioned one of these Arachnida to be mis-^ 

 taken by a naturalist for a Coleopterous insect, of which 

 the head and elytra were represented by the abdomen and 

 antennae of the Spider ! But before we proceed deeper 

 into the discussion of analogies, the annexed table of afh- 

 nities ought to be examined with care.
