COLLECTING ON THE GIRIWA RIVER 179 



I have had it described to me by the natives, and one 

 of my collectors told me once that he saw one. 

 Troides alexandrae does not occur farther inland than 

 about twenty miles, and it is only after crossing the 

 Kumusi some forty miles' distance from the coast 

 that one can reckon on getting Troides goliath. 



That trip, however, has yet to be made. After 

 the Solomons, I was tempted to explore Dutch New 

 Guinea : but this year, or the next, I hope to get 

 farther into the Papuan Hinterland from Giriwa 

 River. I am convinced that there are some fine 

 discoveries yet to be made in the inland valleys 

 among the great mountains of British New Guinea.
