DISCUSSION.
It is believed that a more intensive survey of these hosts will un- doubtedly reveal many more species than the twenty odd species listed here. The majority of the animals slaughtered in Hong Kong are imported from Indo-China and a certain number from Kwangtung province and therefore Hong Kong cannot be considered as a unit separate from China from the standpoint of the parasitic fauna though it may have its own peculiarities.
ACKNOWLEDGMENTS.

He also wishes to thank Mr. Old, the Inspector of the Abattoir, for space and facilities for carrying on preliminary examina- tions at the Abattoir.
