TERTIARY FAUNA OF FLORIDA 



under the prior name of those already given, he made the mistake of giving 

 a wholly new name, Psammocola, and arranging the others under it as sec- 

 tions. The name Psammocola is therefore inadmissible. He cites under it P. 

 vespcrtina Gmelin (as vespcrtinalis) and an Asaphis, but the genus must be 

 regarded as void. Subsequently Deshayes applied the name of Capsella (1854, 

 not Capsella Gray, 1851; Capsula Reeve, on plates, 1857, not Capsula Schu- 

 macher, 1817) to Lamarck's group, which is almost exactly intermediate be- 

 tween Gobraus and Asaphis. 



Gobraus (Leach) Gray, 1852. 



Type Psaiiunobia vespertina Lam. Synonyms: Solen Megerle, 1811, not 

 Linne, 1758; Psammobia Blainville, 1825, not (Lamarck, 1818) Bowdich, 

 1822; Sangitinolaria Blainville, 1825, not Lamarck, 1799; Azor Gray, 1851 

 (Brit. An., p. 51, not p. 62), fPsammobella Gray, 1851; Psammocola (sp.) 

 Blainville, 1825. 



For convenience may be mentioned here also : 



Psammotellina Fischer, 1887. Type Psammotella ambigua Desh. Syno- 

 nyms: Psammotella Deshayes, 1856, and Reeve, 1857; not of Blainville, 1826 

 (Hermannsen, 1852). This will form merely a section under Sanguinolaria. 



Psammotella (Blainville, 1826, as Psammotelle) Hermannsen, 1852. Type 

 Telllna rufescens Chemn., not Psammotella Deshayes in H. and A. Adams, 

 1856, and Reeve, 1857. Peronaa sp. H. and A. Adams, 1856. The correct 

 name of the type is Tellina operculata Gmelin ; it is also the Tcllina semiplanata 

 of Spengler. It will form a section of Sanguinolaria, having nothing in com- 

 mon, conchologically, with the Tellinas, among which it is usually classed. 

 It is not the Tellina rufescens of Hanley from Peru, = T. Hanleyi V. Berlin. 



Elizia Gray, 1854. Type E. orbiculata Wood (sp.). This shell, except 

 in its excessive inequilaterality and free pallial sinus, does not appear to differ 

 much from the orbicular species heretofore referred to Sanguinolaria or Sole- 

 tellina. 



Amphichoena Philippi, 1847. Sole example A. Kindermannii Phil. ?Ain- 

 phidona Morch, 1858 (lapsus ?) ; not Amphichana H. and A. Adams, 1856. 

 This very remarkable shell should not be associated with such forms as Psam- 

 mobella Gray. 



Heterodona.v Morch, 1853. Type Tcllina bimaculata Linne. Synonyms: 

 Arcopagia Orb., 1853, not of (Leach MS.) Brown, 1827; Liodonax (pars) 

 Fischer, 1887. The anatomy, shell, coloration, and habit of this form are con- 

 clusive as to its relations with Psammobia rather than the Donaces.
