Original description: [Smooth, three-segmented, cephalis missing. Second segment broadly urceolate, passing into the third without a stricture, with loosely longitudinal rows of small pores. Third segment contracted at both ends, swollen posteriorly, with larger round sub-quincuncial pores, seven in a median row, and with three sinuose-lobate broad, longer appendages. Length without appendages and cephalis 175 µ, of second segment 47 µ, of third segment 135 µ, of appendage 86 µ. Maximum breadth 150 µ. Approx. 3 smaller pores in 23 µ, and approx. 1 1/2 larger ones. (Translated from Latin by E.M.R. and W.R.R.)]
