This species has a very wide range over the earth's surface, but 

 it does not differ in sculpture, although a number of authorities 

 have constantly confused the little Tellina (Lucina) divaricata, 

 Linneus from the Mediterranean Sea, with the Lacina divaricata. 

 Lamarck from the West Indies, which is the dentata of Wood. 

 Deshayes in the second edition of Lamark's Anim. sans Vert. 1835, 

 does not even mention dentata. Jay in his Catalogue is also 

 confused ; it gives divaricata. Lam. from the Mediterranean then 

 makes dentata, Wood, a variety from St. Jago de Cuba, West 

 Indies. There is not the least doubt that Jay had all West Indian 

 specimens before him, the small size of the Linnean divaricata of 

 the English Coast, and the Mediterranean cannot in any way get 

 confused with the West Indian, New Zealand, and Australian 

 species, so well known as dentata, for the past 60 years. Professor 

 C. B. Adams in his Contributions to Conchology, Vol. 1, p, 243, 

 1852, re-names the species from West Indian examples under the 

 name of Lucina Americana, then he goes on to say, " We wish to 

 call the attention of geologists and others, who have believed in the 

 great geological antiquity and the wide geographical distribution 

 of the so-called L. divaricata, to the just remark of Phillippi (Zeit. 

 f. Mai. 1848, p. 151.)" " Nomine L. divaricatae plures species 

 confusse, omnes divaricatim striatse." " When the types have been 

 properly distinguished, we believe they will be found to have the 

 ordinary restriction both in time and area. The Linnaean name 

 should be reserved for the Mediterranean species, since Linnaeus 

 assigns his shell to a Mediterrrnean habitat."
