Palaeopeltis inornatus Ameghino

The species is founded on four plates which are without ornamentation, and externally smooth except for numerous vascular perforations. They are of considerable size and entirely characteristic. The one such plate which we found is shown in [fig. 134].
Glyptatelus Ameghino
Glyptatelus Amegh., 1897, Bol. Inst. Geog. Argen., t. 18, p. 507.
The plates of the carapace are similar to those of Palaeohoplophorus, the O-figure being, however, nearer the rear of each plate, and the number of radial furrows being smaller, usually six. We found no specimens of this interesting form. Ameghino has made two species, G. tatusinus and G. malaspinensis.
