emis, Whitfield, Streptorhynchm cardinalis, Whitfield, Strophomma Hecuba, Billinirs, 

 Streptorhynchus Hallie* S. A. Miller). With the close of the Lower Silurian 

 in America, it seems to have abruptly disappeared, though in Europe the 

 species S. antiquata is abundant in the Wenlock in England, Scotland and the 

 Isle of Gotland. In the Niagara and Devonian faunas its place is taken by 

 the genus Orthothetes, with which its affinites are very close. 



SUMMARY. 



Genos STROPHOMENES or STROPHOMENA. 



1820. Rapinesqtje i)ro])osed the name Strophomenes witliout giving either a diagnosis or the 

 citation of any species under the genus. 



1824. Defrance, Tableau des Corps Organises Fossiles, p. H, used the generic term Stro- 

 phomenes, citing Rafinesque as the author. 



182.5. Dk Blainville, " Miuiuel tie Malacologie et Coiichyliologie," vol. i, p. 513, pi. liii, 

 figs. 2, 2a, uses the name Strophomena, citing the name of the genus as one pro- 

 posed by Rapinesqde, and also cites Strophomena rugosa, illustrating the species 

 and giving Rafinesque as the author. 



1827. Dkfranie, "Dictionnaire des Sciences Naturelles," vol. li, p. 151, and "Atlas," re- 

 produced the figures of de Blainville, under the name Strophomemis rugosa, 

 Rafinesque. 



1831. Rafinesque defines the genus Strophomenes (October, 1831), referring to a former 

 publication of 1820; and in Noveml)er of the same year describes two species 

 under the names Str. levigata, and Sir. flexilis. 



1850. Professor King recognized the figui'es of Strophomena rugosa above referred to, as 

 identical with Strophomena (Leptwna) planumbona, Hall, published in 1847. 



This identification has been generally accepted, and the figures of de Blainville, 

 and of the Dictionnaire des Sciences, are recogidzed as a fair representation of 

 the species.
