12. Lucina Janeirensis Reeve, Conch. Icon. June 1850. 



In the Catalogue of North American Shells (Jan. 1, 1847), 

 this species appeared with the name L. lupinus Broc. on the 

 authority of Prof Brown. Finding that it was distinct, I 

 described it before the Bost. Soc. N. H., May 5, 1847, with the 

 name of L. subglobosa, which was inserted in the Proceedings. 

 But the description having been omitted, as before stated, Mr. 

 Eeeve's name must stand.

 This is another of the species of which the name only occurs

 have been described elsewhere. '"
