ARACHNIDA AND MYBIOPODA. 



ALL the species of Acari which I found several of which 

 remain unidentified were taken during the dry season under 

 stones. At this time few animals frequent the dried and parched 

 veld, and it is probable that these parasites then hibernate. 



Solpuga chelicornis, despite its formidable appearance, is 

 attacked by small birds. I once witnessed the Solpuga trying 

 to escape from the persistent attacks of a bird which appeared 

 to be the Cape Wagtail (Motacilla capensis), and I eventually 

 secured the pursued specimen. 



The new species Nephila transvaalica, Pocock, is abundant 

 during the rainy season in the wood-bush. It lives in small 

 colonies in gigantic webs (ante, p. 91). 



The large Myriopod, Spirostreptus transvaalicus,n.\\QVi species 

 now described by Mr. Pocock, is very rare. I obtained two 

 specimens at Pretoria, and no one to whom I showed them had 

 ever seen such a large species before. 



ARACHNIDA. 



BY R. INNES POCOCK, Zool. Dept., Brit. Mus. 



The following is a list of the Arachnida obtained by 

 Mr. Distant in the Transvaal. 



ACARI. 



Of this order several examples of the family Ixodidse were 

 discovered under stones. To only one of these, however, namely 

 Amblyomma hebrceum of Koch, I am able to assign a name. 

 The rest appear to be referable to the same genus Amblyomma. 



SOLPUGA. 



Solpuga chelicornis, Licht. & Herbst. Pretoria.
