with the preceding to form his family Pedipalpi. Tarantula of 

 Fabricius included Phrynus and Thdyphonus. 



Phrynidce. Thelyphonidce. 



Phrynus. Thelyphonus. 



*Architarbus. Nyctalops. 



Order VII. SOLPTJGIDEA. 



Abdomen segmented, distinct from the cephalothorax, mutic at 

 the extremity. Palpi filiform, simple, porrect. Two eyes. 



The mandibles, modified antennae, are very large, didactyle, 

 and without a poison-gland. The palpi are in the form of legs 

 or of antennae, and, like the first pair of feet, are without claws. 

 The body is hairy. 



These Arachnids are found in the hot countries of the Old 

 World. They are very ferocious ; Galeodes will attack and kill 

 small mammals, biting into them until its jaws have attained a 

 vital part.

Galeodes = Solpuga. Rhax. Gluvia. 



Aellopus. Gaetulia. Datames. 



Order VIII. ARCTISCA. 



MACROBIOTIDA. TARDIGRADA. COLPODA. CORMOPODA. 



Minute, worm-like animals, with eight very short, indistinctly 

 triarticulate feet. Cephalothorax and abdomen united. 



The mouth is suctorial, with two styles, the rudiments of lateral 

 jaws. There are no respiratory organs nor heart. The last pair 

 of legs is given off from the abdomen. They are mostly herma- 

 phrodite. 



The Arctisca are known as "water -bears;" they are very slow 

 in their movements, and are found in damp places. They were 

 originally grouped with the Eotifers, and, like them, they regain 

 their vitality after being desiccated, and apparently dead, for many 

 years. They are oviparous ; the eggs are very large, and the 

 young have the same number of legs as the adult.
