66 TRANSACTIONS OF THE [DEc. 9, 
STATED MEETING. 
December 9th, 1895. 
The Academy met, with Prof. Brirron in the chair. There 
was an attendance of about thirty (30). 
In the absence of regular business, the Biological Section at 
once organized, Prof. William Stratford becoming Temporary 
Chairman. 
On motion of Prof. Stratford, a report of the Huxley Me-

The nominating committee then reported the names of Profs. 
J.G. Curtis and C. L. Bristol as candidates for the Sectional

Secretary to cast the vote electing them was carried. 
Prof. C. L. Brisron presented a paper on “ The Classification

an examination of a great range of specimens from New England 
to Dakota that coloration could in no way be depended upon 
for the determination of species, and that a careful examination 
of his material, based upon a study of metameral characters, 
rendered it exceedingly probable that no more than a single 
species is represented in this country. 
Prof. Henry F. Osporn, deferring his paper on the “ New and 
Little Known Perissodactyla of the Lower Miocene Lake Basin, 
South Dakota,” referred briefly to the work of the American 
Museum in preparing for the exhibition of skeletons of the 
Titanotheres, and exhibited a number of drawings and a lantern 
slide showing the entire skeleton of Zitanotherium robustum. 
This is remarkable in possessing but twenty dorso-lumbar verte- 
bree, a number identical with that typical of the Artiodactyla, 
but entirely unique among Perissodactyla. It now appears 
probable that the development of horns in the Titanotheres was 
a purely sexual character, and that the genera Titanops, Marsh,
