series, from the marine tertiary to the Carboniferous eoal-mea.sures, are 
successively exposed along the line of the Texas Pacific [Railroad from 
Elmo to Millsap. The most interesting feature of Mr. Hill’s paper, how- 
ever, is that he demonstrates the existence of a marine group of the Cre- 
taceous in Texas lower than any heretofore recognized in America, and 
completely clears up, by methods of stratigraphic palaeontology, the vague- 
ness that has hitherto accompanied our knowledge of that region.”

(Am. Jour. iSci., HI, XXXilTI, 291-303), in which the writer protests 
against the duplication of names in the classification of the Cretaceous

American Naturalist, Yol. XXIII, pp. 160-165. Feb., 1889. 
“While the Equus Reds lare found at various localities in North America, 
the greater number of eharaeteristie species of vertebrata have been ob- 
tained in three regions* .First, the Oregon Desert; second, the country of 
the Nueces, 'S. W. Texas; third, the Valley of Mexico. I give lists of the 
species found at these and their localities.” 
The list from [S. W. Texas is as follows: ^‘Equus harcenaei, Cope, E. 
fraternus, Leidy, E. excelsus, Leidy, E. OGcidentalis , Leidy, E. crenidens, 
Cope, Elephas primigenius, 'Blum., Cams sp., Glyptodon petaliferous , Cope, 
Cistudo marnochii, ICope,” p. 161. An enumeration of the species common, to 
the Valley of Mexico and the Oregon Desert is given. “Of these, the Equus 
excelsus, and Elephas primigenius have been found in IS. W. Texas. These 
species, with the Equus harcenaei, E. crenidens, and probably the Glypto- 
don petaliferous are common to the last named locality and the Valley 
of Mexico.” iP. 164.
