 Vol. LI, page 597, pi. 55, fig. 3, 3 a— f. 



The form from Tømten is referred to Walcott's species, which is described 

 and depicted thoroughly. 



This form was first mentioned and depicted by Th. Kjerulf. Walcott 

 refers it, although with some hesitation, to Obolella Mobergi, the description 

 of which is based upon specimens from the Lower Cambrian sandstone in 

 Skaane, from a somewhat older zone than that of the Holmia shale.
