THE SPIDERS OF EPPING FOREST. 53 



rather broad at the base, attenuated towards the extremity, inclined towards the 

 labium but never touching in front of it. Palpus. Female : either without a 

 terminal claw, or else with a rudimentary one. Alale : tibia of a swollen form, 

 without ajiophysis ; tarsus small and oval ; palpal organs very simple and usually 

 •quite exposed. Legs of moderate length, usually nearly equal, the posterior 

 being the longest : coxae of a swollen form, those of the fourth pair being very 

 widely separated : femora somewhat clavate : patellae practically alike in all the 

 legs: tibiae, metatarsi, and tarsi slender: tarsal claws 2, borne upon a small 

 •onychium. Abdomen oval. Spinners normal : cribellum absent. Tuhe tracheal 

 •openings very obscure : in fact I am not at all convinced that distinct apertures 

 .actually exist in all the species in this family. Female genital aperture simple, 

 without special armature. 



The spiders included in the family Oonopidae are all of small 



size. One genus, Oonops, is found in Britain. 



Genus OONOPS, Templeton. 



Spiders of a reddish tint, with soft integuments. The tibiae 

 and metatarsal oi legs I. and II. are furnished with a double series 

 of long spines. One species only has been found in Britain, and 

 that occurs, though rarely, in Epping Forest. 



Oonops pulcher, Templeton. This species has been taken 

 at Chingford and Theydon Bois. It is very liable to be passed 

 over, as it has every appearance of being newly-hatched, and 

 would therefore be easily mistaken for the young of some larger 

 spider, Dysdeva, for instance. 



Family SCYTODIDAE. 

 Cephalo-thorax variable, almost almost without longitudinal stria. Eyes 6 (8 

 in one exotic genus). Falces more or less weak, almost cylindrical, without basal 

 protuberance : fang short, thick at base, sharply attenuated. Labium rather 

 large, longer than wide, attenuated, obtuse, usually somewhat constricted at the 

 base, not separated from the sternum, but the line of junction is indicated by a 

 deep impression. Sternum usually more or less prolonged posteriorly. Maxillae, 

 strongly inclined towards labium, and convergent,. wide up to the point of insertion 

 of the palpus, then narrow and parallel-sided Palpus : Female without terminal 

 claw : Male palpal tibia without apophysis, palpal organs greatly exposed, simple 

 in structure, but often highly developed. Legs long and slender, coxae almost 

 always alike in the four pairs : tarsal claws 2 or 3 borne on a small onychium, 

 never' accompanied by claw-tufts or scopulae. Spinners small and closely- 

 grouped : cribellum absent. Anal tubercle present, but very small. Tube 

 tnxcheae terminating in a single opening. Female genital aperture without 

 special armature. 



The Scytodidae are chiefly tropical and sub-tropical spiders, 

 one genus only being represented in Britain. 



Genus SCYTODES, Latrcille. 

 Spiders with 6 eyes, arranged in three widely separated
