SOUTH AMERICAN NOTES.! 
BY DR. WM. H. RUSH, U. 8. N. 
I have been adding lately to my collections many specimens, 
nearly all the work having been done near Maldonado, but few spe- 
cies being added, and they include the Unios Rhuacoica and 
Charmana, a fine, large Anodonta, Azara labiata, Solecurtus Pla- 
tensis; and some fine, large, clean specimens of Mytilus Platensis, 
taken from the flukes and shank of an old anchor grappled here. 
This old anchor proved to be quite a blessing in disguise, for on it 
were some fine specimens of Chiton Tehuelchus and C. Isabellei, and 
a few large Ostrea Puelchana. In my dredgings since, I have found 
a few more Chitons, but always on rocky bottoms and attached to 
stones, so that while adding only a few of these, I have been adding

told me that he had occasionally found in his garden a large black 
slug. The day following proving pleasant found me on my way to 
hunt the monster, but anxious as I was for the little game of hide 
and seek, I found time on the way to loiter in a small patch of 
native trees to hunt for my old friends, the Helix costellata d’Orb., 
to add to the number of my accumulating exchanges. Finally I 
found Mr. Burnett and we started for the old ruins of a house. I 
did not anticipate much success when we entered the enclosure, for 
the ruins were in the center of the town of Maldonado, whose popu- 
lation is about twelve hundred, and the surroundings were 
extremely dry, there having been no rain for months. However, 
with willing hands we started in and after turning over many large 
masses of brick, my companion said, after the exertion of moving 
an extra heavy one allowed him to recover enough breath to speak, 
“There is one of those large mail-coated insects I was speaking of,” 
I promptly said, “Hold on!” and proceeded to turn out with my
