IV. Types should never be placed in the exhibition services of 
a Museum. (Vol. II, Mémoires, p. 361.) 
Herr Klapálek (Prague) schliesst sich dem Anträge des Herrn 
•Vorsitzenden an und hält es für wichtig, dass es diesen Instituten 
zur Pflicht gemacht werden soll, dafür zu sorgen, dass die Typen 
durch genaue, wo möglich farbige Abbildungen allgemein zugäng¬ 
lich werden. 
Hon.W. Rothschild (Tring) supported Dr. Holland’s conten¬ 
tion for preservation of types by the example of the errors caused 
by the confusion in the genera of fossil shells Murchissonia and 
Aclesina owing to the temporary loss of the types of Murchissonia 
striatala and M. subsulcata. 
Mr. Malcolm Burr (Dover) said that it was essentiel to create 
a healthy public spirit, in order that it should become a general 
accepted principle that the ultimate destination of all types, with 
full data and author’s signature, should be the great national 
collections. 
It appeared to him essential for monographs, that authentic 
specimens should be sent to specialists, for we can not expect 
them to travel from museum to museum to compare material. Even 
if they were able to do that. The comparison would be dependant 
upon the memory unless they were able to carry the types from 
one place to another. 
Speaking as a worker who had experienced the greatest courtesy 
from almost all the museums of the civilised world, he had found 
that any value, which might eventually be attached to his work, 
would be entirely due to the fact that he had been able to see with 
one pair of spectacles, so to the speak, an overwhelming proportion 
of the types of the species of the group in which he was interested, 
and without such assistance, he would have found it impossible to 
make any progress whatever in his studies. 
The Congress had full legislative power, but little executive 
strength; but if a healthy public spirit were created, that alone 
would be enough to justify this great Congress, if no other results 
had been attained. 
M. Schaus (Londres). — He makes it the practice of giving his 
original type of new species to the National Museum in Washing¬ 
ton, his second specimen to the British Museum.
