1901.] 0?r THE ARAOHTSriDA OT THE " SKBAT EXPEDITIOIS^." 45 



3. Ou the Araclmida collected during the " Skeat Expedi- 

 tion " to the Malay Peninsula, 1899-1900. By M. 

 Eugene Simon, President of the Entomological Society 



of France \ 



[Eeceived April 15, 1901.] 



[This collection of Aracbnida contains examples of 129 species, 

 of which 48 are described as new, and there are also 4 new sub- 

 species. Three new genera are characterized. A few species of 

 Acariua — chiefly Ixodidae — were obtained, but have not been de- 

 termined. Not one of the members of the 8keat Expedition was a 

 specialist in Arachnida, so that the large percentage of novelties 

 iu this collection indicates that a great deal of work still remains 

 to be done at this class of animals in the region in question. —
