G. canaliculala has a wider distribution than any other species of 

 this genus, which is restricted, with this exceptiou, to the southern 

 hemisphere and to the tropics. 



An interesting fact concerning this species is that it extends through 

 the tropics to the northern hemisphere along the western shores of the 

 Pacific, and not along the eastern shores, as one w r ould expect. This is 

 still more interesting when we note that this species occurs at the 

 southern extremities of America and Africa.
