G. tatusinus, Amegh., 1897, Bol. Inst. Geog. Argen., t. 18, p. 507.
I reproduce Ameghino’s figure of this species which shows all that is known of the form.

Glyptatelus malaspinensis Ameghino
G. malaspinensis Amegh., 1902, Bol. Acad. Nac. Cienc., Cordoba, t. 17, p. 50.
This species is described (no figure) as about the same size as the preceding, but with subordinate figures in the central O-figure, and also outside of it. A dorsal plate measures 26 mm. long by 20 mm. wide.
GRAVIGRADA
Remains of this suborder are almost as rare as those of the glyptodonts, and apparently for the same reason, unfavorable habitat. We found no remains of this group, but Ameghino has described a skull and some teeth as belonging to this group; so, in order to present a complete view of the Deseado fauna, I give a digest of his descriptions.
