A. — Introduction. 



During a coral reef expedition undertaken in 1898 for Prof. 

 A. Agassiz, of Harvard College, U.S.A., it was our fortune to 

 examine a number of caves existing in the various raised coral 

 atolls of the Fiji and Tonga groups. 



These present many points of interest to geologist and natural- 

 ist alike. To the latter the scarlet .prawns of the Vatu Leile 

 caverns, the unique shell fish from Wangava, and other animal 

 curiosities would furnish special attractions. 



For the benefit of anyone wishing to further examine these 

 caverns, we may mention the necessity of carrying ropes and 

 magnesium wire.
