THE ANNIVERSARY ADDRESS OF THE PRESIDENT, 
J.J. Harris Teatt, Esq., M.A., F.R.S. 
In Gustav Liypsrrém, who was elected a Foreign Correspondent 
of our Society in 1885, a Foreign Member in 1892, and who was the 
recipient of the Murchison Medal in 1895, we have lost a leader 
among palxontologists, whose knowledge of Silurian life was more 
profound than that of any of his contemporaries. Born in Visby, 
the capital of Gotland, on August 27th, 1829, he began his 
researches on the fossils of that island while a master at the 
Grammar School of his native town. The thoroughness and 
originality characteristic of those early papers on the brachiopods 
and corals suggest that isolation from kindred minds and from the 
multitude of books may éven benefit an earnest student by confining 
his attention to the facts of nature. But Lindstrom was more than 
earnest and persevering ; by his zoological studies at Upsala and 
under Lovén, and by his translation, or rather adaptation, of 
Lyell’s writings, he had admirably prepared himself to grapple 
with the problems of structure, of classification, and of strati- 
graphical distribution, presented by the varied fossil faunas of 
Gotland. The excellence of his work led to his being entrusted 
with the description of fossils from Spitsbergen and corals from the 
depths of the Atlantic; it ensured him a hearty welcome from 
London geologists in 1874 ; and in 1876 pointed to him as Angelin’s 
natural successor in the keepership of the Fossil Invertebrata in the 
State Museum at Stockholm. Here he lived and laboured till his 
unexpected death on May 16th, 1901. 
Most of Lindstrém’s paleontological papers deal with corals; and 
of these one of the best known is the memoir on the operculate 
corals of the Palwozoic formations, wherein the enigmatic Calceola 
was first assigned to its true systematic position. Of no less worth 
were his monographs on the Silurian Gasteropoda and Pteropoda of 
Gotland, on the Ascoceratide and the Lituitide, on a Cyathaspis 
of Lower Wenlock age, and on the Eyes of the Trilobites. In con- 
junction with T. Thorell he described Paleophorus nuncius, a 
scorpion of Lower Ludlow age, at that time (1885) the oldest air- 
breather known. Many others of his writings are highly valued 
by paleontologists, while geologists may recall his papers on the 
eleyation of Gotland, on the curiously disturbed strata of the
