H.R.H. The Prince of Wales was elected an Honorary Fellow of the Society. 
The Keith Prize for the Biennial Period 1917-1919 was awarded to Professor John Stephenson, 
Lieut. -Colonel Indian Medical Service. He.joined the service in 1895, and was for eleven years em- 
ployed on military duty, on plague service, and as civil surgeon. In 1906 he was appointed Professor 
of Biology in the Government College, Lahore, and for some years he has been Principal of the 
College. Soon after his appointment as Professor he began to publish the results of his studies 
on Indian Oligochaeta, and the twenty-six papers published during the period 1907-1919 bear 
witness to his devotion to research and his untiring industry. 
The majority of these papers are of a systematic character, and by his detailed study and careful 
description of mature examples Professor Stephenson has added much to our knowledge of the 
structure and comparative anatomy of Oligochaeta, both fresh-water and terrestrial. But besides 
these studies of anatomical and systematic features, the author has kept in view the broader 
issues of his work and has drawn attention to many matters of general interest connected with 
the zoogeography and the phylogeny of Oriental Oligochaeta. Special mention should be made of 
Professor Stephenson’s memoirs on gill-bearing aquatic Oligochaeta. 
Finally, reference should be made to his observations on the phenomena of anti-peristalsis in 
Oligochaeta, first presented in his thesis for the degree of Doctor of Science in 1909 and afterwards 
extended into a memoir published in the Transactions of this Society in 1913. This memoir makes 
a substantial contribution to our knowledge of anti-peristalsis and intestinal respiration in 
Oligochaeta and other Annelids.
