Blanco and 'G-oodnight (beds not only present new species, but are strictly 
intermediate between the Loup Fork and Bquus beds, and, as be says, 
more strictly Pliocene in character than any of the interior lake deposits 
heretofore described. 
“'The paper here presented is therefore of importance, not only as defi- 
nitely determining the ages of certain portions of the Plains deposits, but 
as ,a valuable addition to our knowledge of these most interesting forms of 
life which were the precursors of tho'se of the present.” From Introduction 
by E. T. Dumble, p. 9.

Tomiopsis — description of a tooth upon which the new genus is founded. 
“The general characters of this tooth are those c^f mammal of the order 
Bruta ( Edentata ) . It resembles no known form of the order, but might 
be said to be intermediate between those of an armadillo and a sloth.” 
iSipeeific characters. 
“This animal left its remains in a bed of probably Neocene age, which 
is exposed on the Lapara creek in Western Texas. It was associated with 
the scales of Lepidosteus, and the bones of Trionyx and a tooth of a croco- 
dile, which do not furnish an exact clue to the age of the formation.” 
f The specimen was obtained by State Geologist Dumble.

Description of a Lower J aw of Tetrabelodon sliepardii Leidy. 
Proceedings of Acad, of Xat. 'Sciences, Phila., Pt. II, pp. 202- 
204. Apr.-'Sept., 1893. 
“This species ‘has been known hitherto by a third inferior molar only. 
This has been described or figured at the following places of reference: 
Mastodon shepardii Leidy, Proe. 'Acad., Philadelphia, 1870, p. 98; 1872, 
p. 472. Cope, American Naturalist, 1884, p. 524. 
Dihelodon shepardii Cope, Proc. Aaner. Philosoph. Soc., 1884, p. 5, par- 
tim. 
Mastodon ohservus Leidy, partim, (Report U. 'S. Geol. Survey Terrs., I, 
ip. 330, pi. XX'I, 1873. 
“A lower jaw of this species, lacking the condyles and supporting the 
second and third true molars, was taken from the bluff in Crosby county, 
Texas, from the same excavation that yielded the Pliauchenia spatula 
Cope, and within fifty feet of that at which the tooth of the Dihelodon prae- 
cursor was obtained^ It came into possession of Mr. M. M. Cox, of Esta- 
cado, from whom I obtained it by purchase after my return from Texas. 
The acquisition of this specimen is important as enabling me to determine 
the true characters of the species* (Besides the last inferior molar, Leidy 
has referred to it provisionally a fragment of a tusk, which, like the 
molar, came from California.”
