| The tail of this description of pup is in many instances armed with a mucro, or sharp point, emerging from its upper side. |
| The leaves are deciduous, and they are ovate, slightly hairy, and terminate in a mucro or stiff point. |
| However, populations of B. xylophilus were subsequently discovered in the USA which also carried a mucro on the tail. |
| In addition, the posterior plate of this chiton shows a distinct mucro. |
| Its separation from other species of the 'xylophilus' group is mainly based on female tail shape, spicules size and the mucro length. |
| Furthermore, juveniles with a long antennule and a mucro were classified as being of the species Bosmina coregoni. |
