t 



July, 1911, and May, 1915, as a part of "Ticks. A Monograph of 

 Ixodoidea" by Nuttall, Warburton, Cooper, and Robinson (Cambridge 

 University Press). Those who wish to go into the systematic or biologic 

 studies of ticks further should consult the monograph above mentioned. 

 Three parts of it have been issued. These cover the Argasidae and the 

 genera Ixodes and Ha^maph3^salis. Dr. Nuttall has also published a. 

 number of important papers on habits and notes on biologies of the 

 ticks. Most of these appeared in the Journal of Parasitology, Cambridge. 

 In South Africa, Prof. C. P. Lounsbury has done a large amount of 

 work, especially on the biologies of ticks. Many of his articles appeared 

 in the Agricultural Journal of Capetown, in the Transvaal Agricultural 

 Journal, and in the reports of the Government Entomologist, Cape of 

 Good Hope Department of Agriculture. A summary of Prof. Neumann's 

 systematic work with descrij^tions and tables for differentiating species 

 has been published as "Ixodidae" (in Das Tierreich, 26 Lieferung, pub- 

 lished by T. E. Schulze, in Auftrage der K. Preuss. Akad. d. Wiss., Berlin, 

 1911. R. Friedlander & Sohn). In the United States the principal papers 

 are a "Revision of the Ixodoidea" by Nathan Banks, 1908, Bureau of 

 Entomology, Technical Series, Bulletin 15, and several papers on tick 

 biologies by Hunter, Hooker, Bishopp, and Wood, the most important of 

 these being issued as Bulletin 106 of the Bureau of Entomology.
