Probably no generic term among the brachiopoda has given rise to a greater 

 diversity of expression of opinion among authors as to its vahie and applica- 

 tion. In order to appreciate the inapplicability of the term as now current 

 among the American and European writers, a brief risumi- of its history be- 

 comes necessary. 



In 1820, C. S. Rafinesque made use of the term Strophomenes in the Annales 

 Gt'nerales des Sciences Physiques de Bruxelles, vol. v, p. 232.* This name was 

 not accompanied either by a diagnosis or the citation of any species. The 

 author, after speaking of the difficulties experienced in working out certain 

 groups, says: 



" Par exemple, parmi les tt-rebratules, nous en avons observt'' plus de 60 

 espi'ces, que nous avons dii ranger sous plusieurs nouveaux genres, tels que 

 gonotrema, didionia, dicJisma, pleurinia, stropheria, strophomenes, clipsilis, etc., outre 

 les vrais genres terehratula et produdus. Le seul G. gonotrema, qui comprend 

 les tert'bratules a ouverture anguleuse ailongce et ;i charnit-re tronquee, etc., 

 contient plus de 30 especes." 



The term Strophomenes, Rafinesque, was afterwards used by Defrance, in 

 1824, also without definition, in the "Tableau des Corps Organises Fossiles," 

 p. 6. In 1825, DE Bi.AiNViLLEf made u.se of the term Strophomena, in the fol- 

 lowing manner : 



" Strophomene. Stroplwtmna. — Animal tout-a-fait inconnu. Coquille ivgu- 

 liere symetrique, ('quilaterale, siiln'-quivalve; une valve plate et 1' autre un peu 

 excavee ; articulation droite, transverse, oflrant a droit et ;i gauche d'une
