2 Arachn. 
XI. ARACHNIDA. 
The order Palpigradi —established for the genus Kcenenia —appears now 
to be definitely accepted and therefore is included for the first time in the 
Record. Previous references to Kcenenia seem to have been placed under 
the Pedipalpi. 
The Pentastomida have escaped notice in the Record entirely for some 
time past. They are now added as an appendix to the Arachnida. 
Considerable discussion has turned on questions of nomenclature 
especiall} 1 - of the Aranece. Dahl (38) has published some criticisms of 
Cambridge’s papers dealing with the application of the International 
Rules to the genera of Spiders. The last-named author is pushing on 
rapidly with his description of the Araneida of Central America and 
making considerable additions to the new species of that region. The 
African and European regions have also contributed a good many new 
species to the Record. 
In “Das Tierreich ” new parts have appeared dealing with the u Palpi¬ 
gradi and Solifugce ,” and with the “ Halacaridce and Hydrachnidce .” 
Michael has published a first volume of a monograph on “ British 
Tyroglyphidce ” which promises to be when completed a valuable addition 
to the Literature of Acari. 
The new genera and species catalogued in the following pages may 
be summarised thus :—
