SMITH : RECENT SPECIES OF THE GENUS PIRULA, LAMARCK. 67 



Five or six transverse pale zones, spotted and blotched with brown or 

 purplish-brown, are more or less distinct in most specimens. In 

 addition to these dififerences, there is one which, if I am correct in 

 the identification of Lamarck's P. reticulata with Say's P. papyratia, 

 at once distinguishes it from P.ficoides. It is the superior size of the 

 nuclear whorls. This is pointed out both by Philippi and Kobelt 

 in their descriptions of P. gracilis. 



The locality, Indian Ocean, quoted by Lamarck and repeated by 

 subsequent authors, I regard as a mistake. It is worthy of notice 

 that neither Lamarck, Deshayes, or Kiener have mentioned any other 

 species from the Gulf of Mexico and Florida, or from any other 

 locality in that region. The P. papyratia is not an uncommon 

 species, and was described by Say in the same year, but a month or 

 two before the publication of P. reticulata.
