Habits. — Charles Island, Oct. 4, 1905. Went ashore at 

 Post Office Bay and worked toward the interior. The country 

 is mountainous, but there are some large spaces of level land. 

 Found animal life of every description scarce. I did not see 

 a Tropidurus or a snake the whole day. Saw lots of cat

 with the Tropiduri, getting five. They were in a large lava

 three on account of defective shells. The particular spot where
