pointed out to King the mixture of Greek and Latin roots in his spell- 

 ing of Camerophoria, and King (1850) accepted the corrected spelling 

 as Camarophoria. From that time until 1952 the two spellings were 

 used indiscriminately, each with about the same frequency. 



Dall (1877) was first to recognize the error in Hall's procedure, and 

 to recommend use of the name Stenoscisma for the group containing S. 

 schlotheimi, and for consigning Camerophoria King to its synonymy. 

 Oehlert (1887, p. 1309) described and illustrated 5\ schlotheimi in the 

 Fischer Manuel de Conchyliologie, using the name in the sense recom- 

 mended by Dall, but emending the spelling to Stenoschisma. Hall and 

 Clarke (1894) accepted Oehlert's change in the spelling of the name, 

 but reiterated Hall's earlier (1847, 1867) arguments that Conrad did 

 not have S. schlotheimi in mind when he assigned it to his genus, but 

 actually was thinking of Rhynchonella formosa. Hall and Clarke state 

 clearly ( 1894, p. 188) that they consider R. formosa to be the typifying 

 species of Stenoschisma; this did not establish a new genus with a new 

 type species, however, because they continued to accredit the genus to 

 Conrad, 1839, thus merely emending Stenoscisma. 



Grabau and Shimer (1907) in their book on North American index 

 fossils continued to use the name in the sense of Hall (1847) and Hall 

 and Clarke (1894), but provided yet another variation in the spelling: 

 Stenochisma. Subsequent authors (e.g. Maynard, 1913; Kozlowski, 

 1929) continued to use the name in the Hall and Clarke sense, with the 

 Grabau and Shimer spelling. 



In the meantime, the group typified by Terebratula schlotheimi von 

 Buch was recognized widely and designated by the name Camerophoria 

 (or Camarophoria) King (1844 or 1850). Davidson used it thus in 

 1853, 1858, 1863, and 1880; Geinitz (1861), Meek and Worthen 

 (1866), Waagen (1883), Hall and Clarke (1894), Tschernyschev 

 (1902, 1914), Weller (1910, 1914), Kozlowski (1914), R. E. King 

 (1931), Licharev (1936), Reed (1944), Sarycheva and Sokolskaya 

 (1952) and Dunbar (1955) are important references employing W. 

 King's name for the genus. 



Despite Dall's clear exposition of the case, obviously there was 

 strong reluctance to put King's name into the synonymy of Steno- 

 scisma. Hall's argument that Conrad's original intent for Stenoscisma 

 included an American Devonian form rather than the Permian .S. 

 schlotheimi was restated as late as 1955. Cooper ( 1942, p. 229) recalled 

 attention to Dall's (1877) statement, pointed out the clear designation 

 of the type by Conrad, and revived Stenocisma (sic) in favor of Cam- 

 arophoria King. In 1944 Cooper illustrated specimens related to 5\ 

 schlotheimi, included Camerophoria in synonymy, and used the name
