Genus VIII. Aranea, the Spider. 

 Linn. Syft. Nat. Pag. 1030. 



The feet of the [Aranex are eight in 

 number. 



They have eight eyes. 



Their mouth is armed with two crotchets. 



Their palpi are two in number, articu- 

 lated, and headed by the genitalia of the 

 males, in that fex. 



The anus contains inftruments for fpin- 

 ning, fhaped like nipples or teats. 



Schasffer adds to the above characters of the 

 Spider, that the feet are made for running, the 

 head united to the thorax, and the abdomen 

 (which is of an oblong oval form) joined to the tho- 

 rax by a fhort ftalk or pedicle. He has divided 

 this genus into different families, according to the 

 various fituation of the eyes, in which he followed 

 Frifch, Geoffroy, and others. The eyes of fpiders 

 are immoveable, and their ftructure is different 

 from that of the eyes of mod other infects, 

 confiding each of only one lenfe, which deprives 



3 them
