CURRENT LITERATURE. 
Part 3, of Vol. XXXIV., of the Proceedings of the 
Linnean Society of New South Wales was issued on Decem- 
ber 3rd, 1909. To this part Mr. T. Harvey Johnston, M.A., 
B.Sc., contributed two papers, the first ‘“On Some Hemo- 
gregarines from Australian Reptiles.’’ This is a pioneer 
paper in this field of research, as the subject is one that has

only. four of these parasites are known to occur, and they 
are found in the blood of the diamond-snake, Python
