Guide to Arachnida. 
Table-case the world. In Europe they are found in Spain, Greece and 
No ' 24 ' Southern Eussia, whilst in America, they are distributed from the 
Southern States of the Union to the Andean Chain in Chile and 
the Argentine Eepublic. They are entirely absent from Austra- 
lasia, China and Japan. 
There are three families: — 1. Galeodidae ; 2. Solpugidae ; 
3. Hexisopodidae. 
Eam. — Galeodidae. 
In the Galeodidae, the flagellum of the first appendage is 
always lancet-shaped. Large hairy claws are present on the legs 
of the three posterior pairs. A narrow 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 arabs (Fig. 67), a North African species, 
with a wide distribution, are placed in Table-case 24. 
Fam. — Solpugidae. 
In this family the flagellum 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. 
Eam. — Hexisopodidae. 
These Solifugae have the legs of the fourth pair without claws. 
The abdominal stigmata have no plates above them. 
The two genera ( Hexisopus and Chelypus) 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 differ from the scorpions in many 
important characters. The “ cephalothorax ” (prosoma) is covered
