This specimen forms No. 2823 of the Yale University collection. It was found in the Niobrara deposits, near Monument Rocks, Gove County, Kansas. It furnishes all the neurals, and the nuchal; large portions of all the costals of the right side, except the fifth; the proximal ends of all the costals of the left side; all the peripherals of the right side, except the fifth to the eighth inclusive; all of those of the left side, except the first three and the seventh, ninth, and eleventh. Of the plastron there is present a considerable part of the right hyoplastron and hypoplastron. A number of Wieland's figures are here reproduced. As to the distinctness of this species from all that have hitherto been described there may be doubts, which it is too early to remove. Of two of the described species, T. brachyrhina and.

Of T. lata, ini\ only small portions of the shell are known; but to judge from the figures of the nuchal that have been publisht, the species is distinct from T. bauri. The latter appears pretty certainly to be distinct from T. stenopora. Of the carapace of T. serrijer Cope there are known only two peripherals, apparently the eighth and the ninth
