Plastomenus acupictus, Hay, Bull. Amir. Mus. Nat. Hist., xxiii, 1907, p. 852, plate liv, figs l-:, text-fig. 8. The fragmentary remains of this species are a part of the Cope collection in the American Museum of Natural History. The catalog number is 1025. The bones were collected for Professor Cope many years ago, apparently from Torrejon deposits, in New Mexico, by Mr. David Baldwin. The individual was a small one. A costal bone, believed to be the third, is 10 mm. wide and 3 mm. thick at the neural border. The seventh costal is 16 mm. wide at the distal end, 3 mm. thick at the sutural edge, and mm. thru the ridge formed by the rib. On the hinder costals are seen 6 or 7 welts. The pits covering all the upper surface except the beveled free bor- der, are unusually small, there being 5 in a line 5 mm. long. The hinder lobe had a width of about 60 mm. at the base. The suture between the hypoplastron and the xiphi- plastron (fig. 629) is 27 mm. long. At the bridge the hypo- plastron is 8 mm. wide and 5 mm. thick. As in other species of the genus, there seem to have been no fontanels on the midline of the plastron. There are no welts on the plastral bones and the pits are somewhat smaller than on the carapace.

National Museum and bears the number 1138. It was discovered in the Wasatch Eocene beds, in the region of the Gallinas River, New Mexico. When Cope came to figure the speci- men, i
