 Streptorhjnchus 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. antiqmia is al)undant in the Wenlock in England, Scotland and the 

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

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



SUMMARY. 



Genus STROPHOMENES or STROPHOMENA. 



1820. Rapinesque proposed the name iSTROPHOMENES without giving eitlier a diaguobis ur the 

 citation of any species under the genus. 



1824. Defrance, Tableau des Corps Organises Fossiles, p. ti, used the generic term 8tro- 

 PHOMENES, citing Rafinesqde as the author. 



182.5. De Blainville, " Manuel de Malacologie et Conchyliologie," vol. i, p. 513, pi. liii, 

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

 posed hy Rafinesqde, and also cites Strophomena rugosa, illustrating the species 

 and giving Rafinesqde as the author. 



1827. Defrance, " Dictionuaire des Sciences Naturelles," vol. li, p. 151, and "Atlas," re- 

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

 Rafinesque. 



18:il. Rafinesqde defines the genus Strophomenes (October, 1831), referring to a former 

 publication of 1820 ; and in November of the same year describes two species 

 under the names /Sir. levigata, and Str. flexiUs. 



1850. Professoi' Kinc; recognized the figures of Strophomena rugosa alxive referred to, as 

 identical with Strophomena {Leptaena) planuinhon.a. Hall, published in 1847. 



This identifii-ation has been generally accepted, and the figures of de Blainvillk, 

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

 the species.
