FAMILY ERESIDES. 



DISTINGUISHING character of this family is the 

 broad, somewhat quadrate cephalo-thorax, of which the 

 caput is usually very convox, and much raised above the 

 level of the thorax. The eyes form an enormous, nearly square 

 figure, on the frontal part of tho caput ; the legs are strong, 

 and the metatarsi of tho fourth pair in the females have 

 calamistra, while both sexes are furnished with a supernumerary 

 spinning organ immediately in front of the ordinary spinners. 

 Tarsal claws 3. 



Tho spiders of this family are not very numerous, and most 

 of them are tropical or sub-tropical. Mons. Simon has lately 

 divided them into several genera. One only is represented in 

 England, and that by but a single species.

Tho four outer eyes form a large quadrilatoral figure, occupy-

 others describe a small figure of the same form just within the 

 straight line formed by the two foremost of the other eyes, and 

 intermediate between them. The maxilla) aro straight, enlarged 

 and rounded at their extremities, and not inclined to tho labium, 

 which is rather long and pointed at its apex. Legs, 4.1.2.3.
