Telson and uropod 3 unarmed. Remarks. This species is at once distinguished by the excavate hind margins of 2nd joints of peraeopods 4 and 5. The beading on side-plate 3 is much finer and more close- set than in the other species. The colour (as preserved) is an opaque creamy white like porcelain. Genus Thaumatelson, Wlkr.
