The clielicerm are rlielato, but the pedipiilps are loug auil leglike and posscsH glands which in have been siH)p()sed to bo [xjjsonous. TIih anterior pair of legs lacks tht^ terniiual ungues found on the others, and functions as a second pedipalp rather than a walking-leg. No appendages occur on the abdo- men. Three pairs of stigmata occur ou the ventral surface of the body, the most anterior i)air being situ- ated on the first thoracic segment, while the other two are on the second and third abdcuninal seg- ments. The anterior posititm of the first pair is probably to be regarded as secondary, and produced by a forward migration of the pair which should occur upon the first abdomi- nal segment. The stigmata lead into tubular tracheso which branch extensively. A comparatively simple heart is situated in the abdomen. The mid-gut possesses numerous branched diverticula as well as Malpighian tubules. The nervous system consists of a syucerebrum connected with a snliMSophageal mass which represents all the thoracic and abdominal ganglia fused to- gether. Two eyes are present, situated on a common eleva- tion at the front edge of the head. The reproductive organs resemble those of the Scorpions except that transverse anastomoses do not occur, and the gen- ital o})ening is situated upon the ventral surface of the first abdominal segment. The Solifugje is a small order living more especially in warm sandy regions. The}- are usually, ou rather insufficient grounds, supposed to be capable of inflicting a poisoned wound. Only two genera, Solpitga and Galeodes, belong to the order. Fio. 20ii.—Onleo<ie8 spiniptlpus (from CrviKK)..
