 Below the Curaray the sand bars yielded turtles' eggs of a

 were smaller and oval, and buried only six or eight inches 

 deep, thirty in a nest. 



December 9. — Passed early this morning the mouth of 

 the Mazan; four huts at the junction. To-day we noticed 

 the anomaly first observed by Herndon. From Papallacta
