本文报道了10种不可知虫，其中包括一新种：Utagnostus（？）nevel，描述了从两个地点内的较低的沉积序列的Radfords溪群，拨号范围槽，塔斯马尼亚州西北部。这两个地区（冈斯平原附近）的动物群都属于中寒武世晚期，一个是Lejopyge laevigata II带，另一个是L。laevigata Ⅲ区和L. laevigata III区或Damesella torosa-Acsionepea janitrix区。
Ten species of agnostid trilobites, including a new species, Utagnostus(?) nevel, are described from two localities within the lower sedimentary succession of the Radfords Creek Group, Dial Range Trough, north-western Tasmania. The faunas from both localities (near Gunns Plains) are of late Middle Cambrian age; one is either of the Lejopyge laevigata II Zone or the L. laevigata III Zone and the other is either of the L. laevigata III Zone or the Damesella torosa-Acsionepea janitrix Zone.
