Of KuTORGiNA the following species have been described by American an- 

 thors : K. cingulata, Billings {he. cit.) ; K. sculptilis, Meek {Iphidea ? ? sculptilis, 

 Meek, referred to KuTORorNA t)y Mr. Walcott*) ; K. pannula, White (Trematis? 

 pannulus, White, referred to Kutorgina by Mr. WALCOTTf) ; K. minutissima, 

 Hall and Whitfield ;i Mr. Walcott§ makes this name a synonym for K. sculp-

In 1868, Davidson identified the species Obolella Phillipsi, Holl, from the 

 Lingula Flags and Lower Tremadoc, as K. cingulata, Billings, and in 1876, Lin- 

 narsson described from the Paradoxides beds of Sweden a simibir form as K. 

 cingulata var. pusilla. 



All the representatives of this genus known are from primordial faunas.
