the bursera trees. I shot the male of a pair wandering 

 through the underbrush. Its mate saw it fall, looked 

 at it for a moment, and then went on searching for 

 food. The song bore a remarkable resemblance to that

 rapidly. 



17 Nesomimus macdonaldi Ridgway 

 Hood Island Mockingbird 



One individual, perched on a shrub, flew off before I 

 could approach closely. 



OTHER VERTEBRATES OF OSBORN ISLAND 



Phyllodactylus bauri Garman 

 Hood Island Gecko 



Collected four and saw three others. All were under stones, 

 and with each was a little pile of the elytra of the beetle 

 Stomion. 



Tropidurus delanonis Baur 

 Hood Island Lizard 



At least eight of these large lizards seen running over the 

 ground. All had an unusual amount of red on the body, 

 and a small one which I collected was almost wholly of this 

 color. 



Amblyrhynchus cristatus Bell 

 Marine Iguana 



Saw three medium-sized specimens, all with a great deal of 

 brick color on the scales. 



Otaria jubata (Gmelin) 



Southern Sea-lion 



About a dozen in the cave, and sixteen basking at one time 

 on the rocky, southeast peninsula. All of this latter group 

 were affected with conjunctivitis, some of the pups being 

 quite blind.
