it, if not identical, was found at Rio de Janeiro, but as only single valves

 ventured to characterise it. 



The soft parts of Pholas Chiloensis are considered very delicate by the 

 inhabitants of the Island of Chiloe, by whom the animal is called 

 " Co-mes." They are found in great abundance at low water imbedded 

 in the rocks near Sandy Point, at San Carlos de Chiloe.

article of food to the ship's company, particularly during the winter

had deserted us. I have named it, in allusion to its affording us a 



grateful, as well as seasonable, supply of fresh food.
