Boring Crustacea in New Zealand. — Chas. Chilton {New Zealand 

 Journ. Science and Technology, 1919, 2, 3-15, 12 figs.). An account is 

 given of two boring Isopods, the gribble {Limnoria lignorum) and the 



Limnoria lignorum Ratke, female. Natural size about 5 mm. in length. 



closely allied L. segnis, and of a boring Amphipod, Chelura terehrans. 

 The damage done by these borers is discussed. The woods known as 

 " totara " and " turpentine " are very resistant, especially the latter. 



Chelura terehrans Philippi, female. Natural size about 5 mm. in length. 



Marine cables are sometimes bored by the gribble. Another borer is 

 the Isopod Sphseroma qiwyana, which can perforate sandstone as well as 

 wood. It has as a constant commensal a minute Isopod, lais puhescens 

 Dana, var. longistylis Chilton. J. A. T.
