 Magazine of Natural History, August, 1891. 



The habits of the Water Spider were first described by de Lignac 

 in a Memoire published in 1749. Since that date many writers, 

 notably Wagner and Plateau, have dealt with the subject. The 

 paper by the last named in the Annales des Sciences naturelles, 

 1867, p. 345, is particularly worth reading. 



E. Peckham deals with "Protective Resemblances in Spiders'- 

 in the publication of the Natural History Society of Wisconsin 

 for 1889. 



The reader interested in the habits of the Wolf-spiders must 

 certainly consult the chapters on " La Lycose de Narbonne " in 

 Series 9 of Fabre's Souvenirs entomologiques. 



The classical account by the Peckhanis, of the love dances of 

 jumping spiders appeared conjointly with the paper byE. Peckham 

 on "Protective Resemblances" cited above. 



For the habits of Atypus affinis (or piceus) the reader is 

 referred to the very complete account given by Enock in the 

 Transactions of the Entomological Society (London, 1885, p. 394) 

 of observations extending through several years. 



The larger Aviculariidae have been dealt with in various papers 

 by Pocock, and the particulars given with regard to DugesieUa 

 were taken from a paper by Petrunkevitch in the Zoologischen 

 JahrMichern, xxxi, 1911. 



In the Archil' fii r Naturgeschichte,i, 1889, Apstein published 

 an admirable piece of research on the structure and function of 

 the spinning glands of spiders. He investigated the glands 

 present in the various families, and the particular arrangement of 

 the spools and spigots on the spinnerets. 



A paper by the present writer in the Quarterly Journal of 

 Microscopical Science for April 1890 continued this investigation, 

 and shewed the special operations in which the various glands 

 participated in the case of the Garden Spider.
