 from extra- Australian hosts, e.g. Gyrocotyle rugosa, Dies., whose 

 anatomy was given by Spencer. In some cases there is merely a 

 reference to the identification of an Entozoon in a host in 

 Australian territory, which has been described elsewhere, e.g. 

 certain tapeworms from the Sunfish. Besides these a number of 

 larval Cestoda have been described or identified from mammals, 

 reptiles, amphibia and frogs by Haswell, Hill, myself and others.

 land. His accounts and figures are very unsatisfactory and do 

 not allow of the recognition of any of them, as his remarks are
