Armadillidium depressum Brandt. [Plate XXV.]

The frontal lobe in Armadillidium depressum is very prominent and much recurved. The antennæ are fairly long and while the two joints of the flagellum are nearly equal they are together not so long as the last peduncular joint.
The telson is slightly longer than it is broad at the base, and its sides are incurved. As in Armadillidium vulgare and Armadillidium pulchellum the outer divisions of the tail appendages are broader than they are long.
The body is flatter than in the other species and bears tubercles; its colour is a slate-grey with yellowish markings. The first thoracic segment is well developed and the head appears as if almost completely imbedded in it.
