Haase gives a revision of fossil Arachnid a , characterising all the 
orders, suborders, and families. The Anthracomarti are referred to the 
Opiliones , which further contain the new suborder Phalangiotarbi , for the 
new genus Phalangiotarbus. In the second part of his work he consti- 
tutes a new family of Pedipalpi , allied to the Palpigradi, for the reception 
of a new genus, Sternarthron, which is established upon the fossils referred 
by Oppenheim to the Orthopterous genus Ckresmodes. One new species, 
Sternarthron zittelii.
