摘要：

A second species of the characteristic Burgess Shale euarthropod Molaria Walcott, 1912 is described from the Sirius Passet Lagerstatte of North Greenland, thus extending its range from Cambrian Series 3 (Stage 5) back into Series 2 ( Stage 3). Molaria steini sp. nov. differs from the type species, M. spinifera Walcott, 1912, in having 9 trunk tergites and lacking an elongate connecting segment between the trunk and the jointed telson. Exopod setal fringes are similar to those in the artiopod Emeraldella Walcott, 1912 from the Burgess Shale but other details of limbs remain obscure.
