Le Guillou's specimens came from Warrior Island. During the 

 Chevert Expedition, we landed for about half a day, but did not 

 procure any living ones, it was very common in the dead state

 dry every thing appeared burnt up. I also found it plentiful at 

 Bet, Sue, Cocoa Nut, Dungeness, and Darnley Islands, all in the 

 Straits, the examples from Darnley were obtained at 600 feet 

 elevation, in clusters of stones at the roots of grass, found at 

 Cape York and Albany Island, North Australia, under decayed 

 wood and leaves near the sea. 



The nine examples from Mr. Beddome do not differ in the least 

 from those found at the other Islands.
