A melancholy interest attaches to the Keport upon the 

 Testaceous Mollusca in the present volume. It was the 

 last piece of work of the late Mr. F. Archer, who was a 

 member of the Committee from the beginning, and has 

 taken an active part in all the work. In addition to all 

 more personal feeling of loss, his ready sympathy, kindly 

 criticism, and sturdy common-sense will be greatly missed 

 at the Biological meetings and on the collecting expedi- 

 tions. Mr. Archer's place on the Committee has been 

 filled up by the election, on June 3rd, of Mr. John Vicars, 

 the Mayor of Bootle. The other reports scarcely call for 

 any special explanation. It is a matter of regret that the 

 state of Mr. T. J. Moore's health has not permitted him 

 to finish his list of the Fishes of the district in time to be 

 included in this volume. 



It only remains for me to express again my cordial 

 thanks to my friends and fellow- workers who have taken 

 part with me in the various dredging expeditions and in 

 the preparation of these reports. Thanks are especially 

 due to our Hon. Treas. Mr. Isaac C. Thompson for the 

 large share of his valuable time which he so ungrudgingly 

 devotes to the management of our financial affairs.
