iv.— ARACHNIDA PEDIPALPI. (Scorpion-Spiders). 



[SEestcrn ®l;ill-cti0e 62]. 



The Scorpion-spiders have strong resemblances both to 

 Scorpions and to Spiders. As in the Scorpions the seg- 

 ments of the abdomen are separate and distinct, but the 

 abdomen itself is either simple, or if there is a post-abdo- 

 men it is in the form of a lash-like appendage without any 

 poison-spine. 



The jaws or "chelicerae" are like those of Spiders, and 

 probably contain a poison-gland ; the " palps", on the other 

 hand, are of the cheliped form like those of Scorpions. 



The lung-sacks are two pairs, placed like those of the 

 Spider Mygale, as may be seen by comparing the prepara- 

 tions displaying the lung-sacks of both, in Cases 60 and 62 

 respectively. There are eight eyes, the disposition of which 

 is intermediate between that found in the Spiders and 

 Scorpions. 



This small Order is represented in Case 62 by speci- 

 mens of Phrynussind of several species of ThelyphonuSy all 

 from India. 



. v.— ARACHNIDA PSEUDOSCORPIONIDEA. (Book-Scorpions). 

 [Western SSlall-rase bS], 



The Book-scorpions are small Arachnida somewhat 

 resembling Scorpions in shape, but having no post-abdo- 

 men or caudal poison-spine. They are found in old books 

 and beneath rotting bark, etc. 



This small order is represented in Case 58 by speci- 

 mens of Chelifer. 



vi.-ARACHNIDA SOLIFUG^. 

 [cEestcrn cHall-case 62]. 

 The Solifug^f represented in Case 62 by fine speci- 

 mens of Galeodes, have a resemblance to the Spiders, their 

 palps also, like those of spiders, being leg-like ; but they
