XI. ARACHNIDA. 
It seems natural, in this connection, to say a few words about Nomen¬ 
clature and Taxonomy. Kraepelix’s “Scorpiones and Pedipalpi” in “Das 
Tierreich” will doubtless be found helpful to specialists as will also 
Canestrini & Kramer’s Demodicidce and Sarcoptidce in the same work. 
The attention of students of the Pedipalpi is drawn to the fact that two 
authors have discovered, apparently simultaneously, that the name Tri- 
peltis is previously occupied, and have both renamed the genus, Cook 
calling it Triplomus and Kraepelix Trithyreus. Kraepelix’s name 
appears to be slightly the earlier but the matter must be left to others to 
decide. It is to be hoped that, small as the point is, one name will be 
finally dropped. 
Amongst the larger systematic works of the year a place of eminence 
must be given to Kraepelix’s “ Zur Systematik der Solifugen.” 
Pocock’s paper on Poecilotheria and Purcell’s on Opisthophthalmits are 
useful works and set an example that might with advantage be followed 
by other specialists. The latter author’s memoirs on the Solifugce and 
Scorpions of South Africa promise well for future studies of the same 
region. 
Pocock deals with a number of species from different parts of the world. 
His papers on Scorpions should be specially mentioned. 
Acari are ever popular and there is no lack of memoirs on them this 
year. Neumann continues his revision of the Ixodidce and Trouessart 
publishes a long paper of preliminary descriptions of species of Sarcoptidce. 
Trouessart’s papers will be found to bristle with new sub-species. 
Especial attention must be drawn to the nomenclature changes published 
in the part of Das Tierreich dealing with Acari. 
The work on the Spiders of Central America in Biol. Centr.-Amer. 
continues. Parts of both volumes have this year appeared. 
Simox’s papers this year deal principally with Spiders from the South 
Pacific and Malay Archipelago. No further part of “ Histoire naturelle 
des Araignees ” has, as yet, appeared. 
Beyond a few small papers nothing more need be mentioned here. 
Saebatixi’s account of a “ ferment anticoagulant ” in Ixodes ricinus is 
interesting. So also is Goldi’s account of the curious spider Epeiroides 
bahiensis. 
Other papers, being principally systematic and faunistic, will be found 
fully analysed in their proper sections of this Record.
