TABLE OF SCALE COUNTS— BliN-DLOE ISLAND— Continued 



Habits. — Bindloe Island, Sept. 17, 1906. We rowed down 

 the coast about a mile to where the brush came down to the 

 beach, and then worked inland toward the rim of the crater. 

 Near the coast the ground is black ashes covered with low 

 brush and a few small trees. Farther inland the brush be- 

 comes very thick, and cactus appears. About one mile inland 

 we found the lizards abundant all through the brush. They 

 keep well under cover, and rarely come into the open. The 

 numerous hawks make them very wild. They are all dark in 

 color, the males being about the color of ' the black ashes. 

 Some have a very prominent dorsal crest. The stomachs of 

 several examined contained vegetable matter. Insects seem 

 to be scarce ; sprouts and green leaves, though not particularly 

 plentiful, form their principal articles of diet. The ovaries of 

 several females were well developed. King worked along the 

 rocks near the water, and found Tropiduri abundant. They 

 seem to range over the rocks along the coast. The belt near 

 the shore where the brush is not thick seems to be deserted. 

 Beginning a mile inland, one finds them again, and they range 

 thence to the top of the island. 



Their "food appears to be wholly vegetable. All stomachs 

 examined contained blossoms, seed-capsules, and berries." 

 (Heller.) 



General remarks. — This is one of the larger species. The 

 males have higher crests than found in any other of the Gala- 

 pagos Tropiduri, and show fewer black markings. The crests 

 of the females are much lower. The sides of the neck are 

 covered with imbricate scales, as in the case of the Chatham 

 Island lizard.
