Mr. Cassin read a letter from Capt. W. F. Lynch, U. S. N., giving 
an account of the finding of human bones from Santos Brazil, presented 
this evening. The cranium was perfect when found, but by accident 
has been subsequently broken. 
Mr. Lea exhibited two specimens of Triqueira coniorta, Lea, (ffyria, Lam.) 
^ which he had received from Mr. Cuming, of London. They were from 
Shanghai, and make four specimens known of this curious and rare species of 
the family Unionidce. Mr. Lea called attention to the fact, that these two 
specimens had both the same curve on the dorsal and basal margins, that the 
two previously exhibited by him and described in the Journal had, thus finally 
proving that the twisted form of this Triqueira is its normal character, like 
Area tortuosa^ Lin. in the Arcades. One of these specimens will be found in the 
collection of the Academy.
