140 Dr. J. C. Melvill on Marine Moll u sea 



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 radulse 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.

This small species, compact, solid, hardly suturally im- 

 pressed, ochreous-banded spirally below, longitudinally closely 

 nodoso-costulate, and transversely elosely decussato-sulcate, 

 possesses a distinction in the protrusive character of two of 

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

t We spell the Moutlortian name, presumably derived from dXeKTpvtov, 

 a cock, with a "y " in preference to i, to conform to the rule of nomen- 

 clature which holds that the Greek " apsilon " equals the Latin (l y."
