past been engaging the attention of J. N. Halbert, of Dublin, 

 whose Report we have now before us.^ It is an important 

 contribution to our knowledge of a comparatively neglected 

 group, and must be consulted by all who are interested in 

 the study of this section of the British fauna. The portion 

 dealing with the Gamasoidea is particularly valuable, and 

 many new species are described. In the notes on general 

 distribution a number of hitherto unpublished Scottish 

 records of Oribatids (by W. Evans) are mentioned. Five 

 plates of structural details amply illustrate the text. 



Conchologists will welcome the appearance of Part 21 

 of J. W. Taylor's splendid JMoiiogfapli of the Land and 

 FresJi-ivater Mollusca of the British Isles. This part 

 completes the third volume and is dated 21st December 

 1914. Since it is made up of Appendix, Bibliography, 

 List of Subscribers, and Index, nothing need be said of 

 the Part itself; but we should like to offer our hearty con- 

 gratulations to the author on the completion of the present 

 volume, and to wish him strength and opportunity to 

 complete what will rank as the finest work on the subject 

 hitherto published, and one which will serve as a lasting 

 monument to his knowledge and untiring zeal.
