7. Odocoileus hemionus eremicus Mearns. Tiburon Island Deer. 



Male and female ad., Tiburon Island; male, antlers only, all from 

 Tiburon Island, April 12. 



Deer are abundant at Tiburon Island if one may judge by their tracks 

 and trails. Several of the animals were seen and two specimens were 

 obtained. The weight of a heavily antlered buck, killed by Lieut. Stanley, 

 was 121 pounds after evisceration. 



8. Odocoileus cerrosensis Mcrriam. Cedros Island Deer. 



Fragments of weathered antlers, Cedros Island. Probably now extinct; 

 killed formerly by miners for food. 



Leporid.e. Hares, Rabbits. 



The collection of jack rabbits although small contains two especially 

 striking forms, the grayish or silvery rabbit of Tiburon Island, allied to 

 species of the Mexican mainland, and the remarkably dark species peculiar 

 to Espiritu Santo Island. The latter with its glossy black back resembles 

 no other rabbit, and is a most striking variation from the form inhabiting 

 the adjacent coast of the Peninsula. 



9. Lepus calif ornicus magdalenae Nelson. Magdalen a Island 



Jack Rabbit. 



Male, Santa Margarita Island, March 20. 



10. Lepus calif ornicus xanti Thomas. Cape San Lucas Jack Rabbit.

11. Lepus insularis Bryant. Espiritu Santo Jack Rabbit.

 Island; female, Espiritu Santo Island, April 18. 



12. Lepus alleni tiburonensis subsp. nov. Tiburon Island Jack 



Rabbit. 



Closely related to L. alleni, from which it differs in being much darker and more 

 iron gray, the buffiness on the back being rather pale and much overlaid and mixed 

 with black.
