140 Dr. J. C. Melvill on Marine Mollusca 



one distinguished in many realms of thought and learning, 

 whose relaxation it was to turn from the study of the Early 

 Christian Fathers and deep Biblical lore*, to such successful 

 research in Molluscan raduhe that his name soon became a 

 household word for accurate and discerning knowledge in 

 this branch of the science, his loss being generally felt to be 

 quite irreparable. After a short illness, he passed away at 

 his Cambridge residence in November .1916, aged 73.

 the five iirate denticulations of the inner side of the lip.
