| Compared with a much more greater specimen this one has a more flattend upper part, the posterior petals not so conspicuously fused, the highest point near to the rear end, a conical cross-section rather in the lower part and the area below the anal opening not sunken. The different numbers of pore pairs in the subanal fasciole may be due to the different size of the test. | |
