Observations. — For reasons published in 1910 I consider that Fritsch's genus 

 Proviygale is a synonym of Anthracomartus ; and since the forms he refers to 

 Hemiphrynus also belong apparently to the same order as Anthracomartus, there is 

 no reason for the retention of his suborder Pleuraraneas. At all events, "what- 

 ever these forms may be, they are assuredly not referable to the Araneae. The 

 other genera assigned to the Araneee seem to belong to that order, so far as can 

 be judged from the author's figures. As for his order Opiliones, it has already 

 been stated that the Poliocherida?, Architarbida?, Anthracomartidas and Eophrynidas 

 cannot be relegated to it nor to any single group of Arachnida, whether it be 

 named Anthracomarti or Meridogastra. Nemastomoicles may be one of the 

 Opiliones, but Dinojrilio, if figured with an approach to accuracy, should find place 

 in the Araneaa probably. In recognising that Geraphri/nus and Architarbus 

 (including Phalangiotarbus) constitute a natimd group, Fritsch improves upon 

 Haase's system. As regards the Anthracomartidge and Eophrynidae, he practically 

 follows my classification, although he places Anthracosiro in the Anthracomartidas 

 and by so doing drops the family Anthracosironidaa. 



Unfortunately, the value of this monograph is lessened by the author's lack 

 of acquaintance with the morphology of recent Arachnida, especially on such points 

 as the constancy of the segmentation of the appendages within ordinal limits. His 

 restorations, therefore, cannot be regarded as correct interpretations of the structure 

 of the fossils.

Reasons are given for concluding that the genera referred by Fritsch to the 

 Pleuraraneaa belong to the Anthracomarti, Prumygale being a synonym of 

 Anthracomartus.
