 and his interleaved copy of the List, as well as that

 deserve the attention of students. They are both in the 

 library bequeathed to the University of Oxford, and 

 housed in the Hope Professor's department.

 the more minute groups of the Theridiidae^ have been re-

 stage farther by Mr. H. Wallis Kew. Such revision

 fully acknowledged the assistance which he gave them. 

 But the bulk of his work will remain as the necessary 

 starting-point for all future students.
