ensis, Whitfield, Streptorhynchus cardinalis, Whitfield, Strophomma Hecuba, Billings, 

 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. 



Genus STROPHOMENES or STROPHOMENA. 



1820. Rafinesque proposed the name Strophomenes without giving either a diagnosis or the 

 citation of any species under the genus. 



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



phomenes, citing Rafinbsque as the author. 



1825. 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 by Rafinesque, and also cites 8trophomena rugosa, illustrating- the species 

 and giving Rafinesqde as the author. 



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

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

 Rafinesque. 



1831. Rafinesque 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 8tr. levigata, and 8tr. flexilis. 



1850. Professor King recognized the figures of Strophomena rugosa above referred to, as 

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



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

 and of the Dictiouuaire des Sciences, are recognized as a fail' representation of 

 the species. 



* "The specific name is given as a compliment to Miss Hallie Cutton, who was the first lady to join 

 the Cincinnati Society of Natural History." — Miller, Cincinnati Quarterly Journal of Science, p. 148. 1S74.
