NO. 2 BRACHI0P0D SUPERFAMILY STENOSCISMATACEA — GRANT 1 59 



plicata (Kutorga) from the Permian of Oregon (Cooper, 1957). 

 Specimens in the U.S. National Museum collections have the external 

 generic features of the genus, but lack the lateral buttress plates of the 

 spondylium. This constitutes the only evidence from specimens that 

 such plates may be lacking in the genus; it does not preclude their 

 presence in other species of Septacamera. 



Range. — Species of Septacamera have been found in the Lower 

 Permian (Sakmarian) in the Ural foothills, and in the Lower Permian 

 of Oregon (Word equivalent). According to Licharev (1960, p. 249), 

 its range extends doubtfully into the Upper Carboniferous in the Ural 

 area and Timan.

Remarks. — 5*. kutorgae is about average size for the genus, as well 

 as can be determined from the literature. It is strongly plicate and has 

 a high fold at the anterior, but the fold is not prominent above the 

 flanks, and the sulcus is not deeply depressed. The anterior is uncinuli- 

 form, with valves meeting in a broad arc, not acutely and not in a 

 plane. 5". kutorgae differs from 5". cf. S. plicata (Kutorga) in its 

 sharper costae, fewer costae on the fold, and less strongly geniculate 

 anterior surface (although the last feature may have been exaggerated 

 by crushing of the anterior of the Oregon specimens). No evidence in 

 Tschernyschev's (1902) work indicates that lateral buttress plates are 

 present in the pedicle valve as Stepanov (1937) contended (see dis- 

 cussion of genus, above) .
