Table-case the world. In Europe they <are found in Spain, Greece and 

 ^°" ^'*" Southern Russia, whilst in America, they are distributed from the 

 Southern States of the Union to the Andean Chain in Chile and 

 the Argentine Eepul)lic. They are entirely absent from Austra- 

 lasia, China and Japan. 



There are three families: — 1. (Utlcodidac ; 2. Sulpiigidac ; 

 3. Hcxifiopodidac. 



F AM . — Ga lend id a c . 



In the Galeodidae, the fiagellum of the first appendage is 

 always lancet-shaped. Large hairy claws are present on the legs 

 of the three posterior pairs. A naiTOW toothed plate protects the 

 stigmata of the second and third abdominal somites. 



There is but a single genus {Galeodes) in this family. The 

 species are very numerous and are confined in distribution to the 

 Old World. They are all quick-running forms. 



Examples of Galeodes arahs (Fig. 67), a North African species, 

 with a w^ide distribution, are placed in Table-case 24. 



Fam. — SoIpiKjidae. 



In this family the fiagellum presents much diversity of form. 

 The claws of the three posterior legs are smooth. There is no 

 toothed plate above the stigmata of the second and third abdo- 

 minal somites. 



There are numerous genera and species of Solpugidae and they 

 have a wide distribution. The genus Solpuga, which is confined 

 to Africa, is the richest in species. The majority of the members 

 of the family are very active in habit, but a number of species 

 {Bhagodes, etc.) are slow and clumsy in movement. 



Fam . — Hexisopod Ida e . 



These Solifugae have the legs of the fourth pair without claws. 

 The abdominal stigmata have no plates above them. 



The two genera (Hexisopits and t'helypus) which compose this 

 family are confined to the dry regions of South Africa, and four 

 or five species only are known. Unlike the great majority of 

 Solifugae, they are slow-moving forms. 



Order 6.— Pseudoscorpiones (False Scorpions). 



These Arachnida are very like little tailless scorpions in general 

 appearance, but in reality they difier from the scorpions in many 

 important chai-acters. The " cophalothorax " (prosoma) is covered
