[This collection of Arachnida 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 

 Acarina — chit- fly Ixodidse — were obtained, but have not been de- 

 termined. Not one of the members of the Skeat Expedition was a 

 specialist in Arachnida, so that the large percentage of novelties 

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

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