The tree-climbing habits of this species have been a subject of 

 so much discussion that I have asked Mr. Gardiner for a special 

 note on the point. He says : — " The robber crab is very commonly 

 found in the tops both of Pandanus and of coconut-trees, from 

 which latter I have had it thrown down to me by the natives. It 

 is stated by them to break ofi" the nuts and often to faU with them, 

 never killing itself, as the coconut is underneath. I have seen 

 them constantly clinging to the fruit of the Pandanus, the fallen 

 segments of which, after they have been chewed by the crab, cover 

 the ground. Although all the specimens are from Funafuti, the 

 crab is also very common at Rotuma." 



Two males and five females from Funafuti.
