﻿IX, B, 3 Light: Dangerous Jellyfish in Philippine Waters 295 



common medusae in Manila Bay, are harmless, and I have handled 

 them on numerous occasions without suffering any sting whatso- 

 ever. Dactylometra on the other hand is known to be very 

 dangerous. Several cases of severe stings inflicted by it are 

 known, and the natives, particularly the fishermen, hold it in 

 great fear. While the symptoms reported by Old were quite 

 different in many ways from the symptoms usually following 

 the sting of Dactylometra and those in the case reported here, 

 and while they may have been due to Lobonema smithii or some 

 hitherto unreported medusa, it seems probable that they were 

 merely the results of very severe poisoning from the sting of 

 Dactylometra.
