We would not have concluded the history of the new members thus added to the ‘‘ Fauna of 
Chile,’ by the exertions of the United States Naval Astronomical Expedition, without in-

nessee. Science owes a debt of gratitude to all the enlightened men, who, by the position they 
hold in the councils of nations, declare themselves the patrons of scientific researches.
