PART THE SECOND. 
THE DIVISION OF SPIDERS INTO TROOPS, CLASSES, GENERA, AND SPECIES. 
CHAPTER I. 
Nature feems to have divided Spiders into two troops : 
Aerial, fpecimens of which occur every day, and 
Aquatic, living in waters, and not fo common. 
Aerial Spiders divide readily into two clafTes: 
1. Retiary, or fuch as weave webs, fome in one manner, fome in another, for catching 
their prey. 
2. Leaping., or fuch as make no webs, but take their prey by leaping on it, as a cat does 
on a moufe, or a hawk on a pigeon. 
Retiary or Web-Spiders, may be diftinguifhed into three genera. 
1. Vertical, or fuch as extend round nets. 
2. Irregular, whofe nets are neither round, nor thick, but compofed of threads croffing 
each other. 
3. Weavers, or fuch as make clofe webs, thick woven like cloth. (Lexfores). 
Reapers are alfo divided into three genera by Lifter. 
1. Lwi, ov Wolves. 
2. Phalangia. 
3. Cancriformes, or Crab-fiaped.
