Department of the University. Mr. Pearson has been 

 working on this Memoir for several years, part of the 

 expenses of his material being met by a grant from the 

 Board of Agriculture and Fisheries, and part of the 

 expense of producing the beautiful plates which illustrate 

 the structure and life-history of the Crab being met by a 

 grant from the fund for research, placed at the disposal 

 of the University by H.M. Treasury, while the remainder 

 of the cost of the plates will be defrayed by the Liverpool 

 Marine Biology Committee. Mr. Pearson has discussed 

 his subject from practically every point of view and has 

 produced an account of the Crab which will, I hope, be 

 regarded as the authoritative work on this important 

 food-animal, and will, I am sure, be a credit to our report 

 and to the Sea Fisheries Committee under whose auspices 

 it is produced.
