CLASSIFICATION 393 



The legs are uearly of equal lecgtli, and the posterior spinnerets 

 have very long terminal joints. 



Fam. 6. Sicariidae (Scytodidae). — The Sicariidae are a small 

 group of six-eyed spiders, usually with weak legs and slow halting 

 movements ; they live under stones or in outhouses. The 

 cephalothorax is generally smooth and devoid of the median fovea, 

 and the palpal organs of the male are extremely simple. The 

 best known genus is Scytodes, one species of which (aS'. thoracica) 

 has on rare occasions been found in outhouses in the south of 

 England, in Dorsetshire, and Kent. This is a remarkable spider, 

 about one-third of an inch long, with a pale yellow ground- 

 colour, marked with black spots and patches. The cephalothorax 

 is smooth and dome-shaped, and highest near the posterior end. 



All the other members of the family are exotic. Loxosceles is 

 found in the Mediterranean region and all over America, as well 

 as iu Japan. The median fovea is present in this genus. Sicarius 

 is a native of America and South Africa. It is of stouter build 

 than Scytodes, and the legs are stronger. Drymusa belongs to 

 South Africa. The peculiar New Zealand species Feriego2)s hirsiihis 

 is placed by Simon in this family, as is also the North American 

 genus Plectreurys, notwithstanding its possession of eight eyes. 



Fam. 7. Hypochilidae. — Two species only are included in 

 this ianiil J, Ifypochil us thorelli of North America, and ^c^a^osi{ici!a 

 davidi, a native of China. They have four pulmonary sacs, 

 though they possess little else in common with the " Thera- 

 phosae." The pedipalpus of the male is very remarkable, the 

 tarsus being almost unmodified, and the very small palpal organ 

 being inserted at its extremity. These spiders are cribellate. 



Fam. 8. Leptonetidae. — The Leptonetidae are small spiders 

 with smooth and usually dull-coloured integuments. jMost of 

 them are cave-living, but some are found amidst vegetable debris 

 in damp spots in forests. The eyes are six in number, and the 

 legs are generally long and thin. There are five genera. Lepto7ieta 

 has about ten species living in caves in the Pyrenees. The 

 single species of Telema (T. te/nella) has the same habitat. Ochy- 

 rocera has representatives in tropical Asia and America, and is 

 somewhat more ornate than most members of the group. Usofila 

 has a single species, inhabiting North America, while Theotina is 

 found in caves in the Philippines and in Venezuela. 



Fam. 9. Oonopidae. — The Oonopidae are very small spiders,
