The text of Duolos (in Chenu 111. Conch.) is somewhat 

 ambiguous ; " Habite la bale de la Madeleine, le golfe de 

 Nicoyo, Costa Rica, Am6rique oentrale, d'oA M. Cuming I'a ' 

 rapportee." The Bay of Magdalena is much farther north 

 than Costa Rica, on the outside of the peninsula of California 

 in latitude 24° 30' N. Probably a different punctuation 

 should have been used, so as to indicate two distinct localities. 



We obtained 17 fine large specimens in the fruit shanty 

 before mentioned. They were said to have been taken 

 " down the bay." Their condition, and the other shells which 

 were with them, fully confirmed the statement.

If Lamarck and Duclos have sometimes gone into the one 

 extreme of excessive multiplication of species, Mr. Reeve has, 

 we fear, in a rare instance of error, gone to the opposite ex- 

 treme, in uniting with O. reticularis, O. araneosa, and O, 

 venulata of Lam., and Duclos' species O. Timoria, O. obesina, 

 and O. pindarina. Mr. Reeve's fig. 16a. represents well the 

 common Caribbean species, 0. nticularis, which inhabits the 

 islands and main land around the Caribbean sea. Fig. IG i
