PAET II (REPTILIA). 



Much that I have advanced in respect of the parasitism of 

 birds holds good in the case of reptiles. I cannot recapitulate. 

 The saurians, ophidians, and chelonians are extensively infested, 

 but in this respect the amphibian frogs, toads, and salamanders 

 are probably the most victimised. If, on the one hand, com- 

 paratively few tapeworms have been found in reptiles, it may, 

 on the other hand, be said that the Echinorhynchi come into 

 prominence, causing serious injury to reptilian hosts. Serpents 

 and chameleons are particularly liable to have their lungs 

 infested by acanthocephalous entozoa, these organs being also 

 attacked by pentastomes. I have received evidence of fatal 

 epizooty amongst chameleons from this source ; and I have been 

 requested to suggest a remedy. To prevent outbreaks of 

 entozoal disease is one thing ; to offer a radical cure when the
