68 Further Notes on Queensland Termites. [Sess. 
while places of solitude were also found. Again, in the 
tenacity with which birds were known to return to their 
breeding-place perhaps lay the whole stimulus for them to 
undertake the long journeys. Next, discussing how birds 
were guided in their migrations, he said they were there face 
to face with the greatest of mysteries. The birds travelled 
mostly at night, and at a very great height, when the organ 
of sight would not be of very much use, while the younger 
birds migrated apart from the parents. Mr Clarke further 
gave as an explanation of why the migrations took place at 
night, that most of the daytime was taken up with the search 
for food, and that by flying at night no single hour was lost. 
Il—FURTHER NOTES ON QUEENSLAND TERMITES.

(Communicated by Mr W. C. CrawForD, President, Dec. 27, 1899.) 
THE thoroughness with which Grassi and his pupil Sandias 
take up the Sicilian termites is very praiseworthy. I may 
again say that I think his book a treat. He has drawn their 
bad habits (speaking from a human point of view) with a 
graphic pen, from which I for one have learned much. As to 
his pencil, it is perhaps rather too diagrammatic. I am at 
least hardly prepared to believe that the two Sicilian genera 
have heads quite so bald, quite so round, or quite so free of 
visible organs, as represented in two of his plates. One of the 
facts the book helps me to realise is, that only the fringe of 
termite history is touched as yet, apparently, by anybody; and 
just as termes differs from calotermes in important details of 
habit and economy, so over the face of the tropic earth, in- 
cluding Africa and Australia, there must be hundreds of 
species differing still more widely from them. Lach different 
form of termitary is probably constructed by a different species
