VIVIPARA CARINATA, Valenciennes. 



Hald., p. 27, t. viii. 

 This is to be expunged from the list of 

 American species. Mr. Binney, having ex- 

 amined a specimen in the Jardin des Plantes, 

 found it labelled in Valenciennes' own hand,. 

 " Philippines." It is decidedly of oriental as- 

 pect.

 1. VIVIPARA INTERTEXTA, Say. 



Hald., p. 31, t. X, f. 1—6. 

 This species appears to be widely distributed. 

 Mr. Say's original locality was New Orleans, 

 but I have received numerous fine specimens 

 collected by Prof D. S. Sheldon at Davenport, 

 Iowa, and Mr. W. G. Binney announces it 

 from South Carolina.
