Shell small, transversely oval, broadest about tlie middle. 

 Hinge-line straight, shorter than the width of the shell ; car- 

 dinal angles roimded. Shell substance apparently corneous. 

 Surface marked with niimerous, sharply marked, concentric 

 lines of growth. 



Length 3 mm. Breadth 4 mm. 



As I have not had an opportunity of examining more than 

 a very few specimens, I have thought proper not to ereate a 

 new species at present, but provisionally to refer this species^ 

 as a variety, to the Kutorgina cingulata of Billings, though I 

 am by no means certain of the specific identity. Imperfect as 

 our knowledge is, as well of the Canadian as of the Scandi- 

 navian form, their agreement in general aspect makes it pr'o- 

 bable that they are at least nearly allied. The greatest dif- 

 ference is in the size, which in the Scandinavian is many times 

 less. It is also more transverse than the specimens figured by 

 Mr. Billings. More nearly it resembles the Englislx figured 

 by Mr. Datidson. In the specimens from Bornholm the only 

 ornamentation of the surface consists in the concentric lines; 

 in a specimen from Östra Ryninge in Nerike there is also a 

 slight indication of radlating ribs. 



This species is rare in the strata with Paradoxides Forch- 

 hammeri in the island of Bornholm (Museum of Copenhagen). 

 One single specimen, a little differing, 1 have found in the 

 strata with Agnostus l^vigatus at Östra Ryninge in Nerike.
