St. Martha; Redfield! St. Thomas; d’Orbigny! St. Mar- 
tha; Carthagena in New-Granada; Krebs! remark: 
d’Orbigny’s locality St. Thomas‘ is surely a mistake ; 
he may have bought it or received it from a collector 
in said place, but we doubt that it has been found at 
the island of St. Thomas, where we have collected shells 
in 17 years and never seen a trace of it; Mr. J. Redfield 
has told us that he always receined M. interrupta-lineata 
Muhlf. and M. obesa Redf. intermixed when the slells 
came from Carthagena, but only M. interrupta-l. when 
they came from Sta. Martha; Mr. Cotoy has told R. 
Swift Esq. that he M. int-st. was always found along 
the shore and M. ob. in 8 to 10 fathoms of water.
