The species of this genus resembles in structure of the thorax those of [/laenus, from 
which they differ by the more arched axis, and the side spines of the pygidium, 
Angelina differs from Giordanella in its flat head, and the margin around it; also in 
the size of its pygidium.

Under the new generic name of Anthracopeltis, the author describes and illustrates 
a pygidium as Anthracopeltis Crepini. 
The pygidium resembles that of Phaeton Barrande, but may be distinguished by the 
shape of the axis, also by a groove which runs around the tail near the base of the 
spires.
