should if possible be sent with the essay. The essay must embody 
studies of several “bursters,” and must be chiefly the result of 
original research of the author, but authors are not debarred from 
availing themselves of any available information published or 
otherwise on the subject. 
Original Scientific Research.—I will now direct your attention 
to some of the scientific work which has been accomplished in the 
Colony during the past year, or is still in progress. At the 
University Biological Laboratory, Prof. Haswell has been chiefly 
engaged in some investigations on the structure and affinities of 
some of the lower groups of Vermes. These have proved interest- 
ing, as they have resulted in the establishment of a more intimate 
connection than was previously supposed to exist between the 
classes Turbellaria and Trematoda. Temnocephala, a dweller for 
the most part on the surface of Australian crayfishes, proves to be 
almost as much a Rhabdocele Turbellarian as a Trematode, and 
can only arbitrarily be assign ed to the one or the other of these two 
classes; and the same may be said to hold good of Actinodactylus, 
an entirely new type, occurring in the gill-chambers of the 
Gippsland burrowing crayfish. The detailed account of Temno- 
cephala and Actinodactylus will appear in the forthcoming Macleay 
Memorial Volume. 
Short papers on various points have been published during the 
year in the “‘ Zoologischer Anzerger,” and the ‘“Abhandlungen der 
Naturfordschenden Gesellschaft in Halle.” Among the “ Jottings 
from the Biological Laboratory,” published during the year, are 
“* Notes on the occurrence of a Flagellate Infusorian as an intra- 
cellular parasite,” “On the occurrence of a second species of 
Phoronis in Port Jackson,” and ‘On an Alloiocele Turbellarian 
inhabiting the underground waters of Canterbury, New Zealand.” 
Professor Wilson and Dr. Martin, at the University Medical 
School, have in hand the following papers for the Macleay 
Memorial Volume :—‘ On some points in the anatomy of the 
muzzle of the Ornithorhynchus,” “On the rod-like tactile organs 
in the skin of the muzzle of the Ornithorhynchus.”
