Of the remaining ten species, he was satisfied that those referred

discovered by Chas. M. Wheatley in the Triassic tracks of Phoenix 
ville, Pennsylvania, which was apparently distinet from the above, 
and of larger size. The remains preserved were dorsal, lumbar, and 
caudal vertebra, with costal and abdominal ribs; left femur and 
“i nearly perfect ; portion of pelvis; ungueal and chevron 
bones, &e. "The femur measured 13 inches i in gemis and the lum- 
bar rm exhibited slender cylindrie diapophyses, which bore 
ribs to the sacrum. This reptile = named Belodon lepturus, and 
was aer to have attained a length of about 12 feet. 
ven ofthe thirteen species being thus disposed of, there re-. 
t ue the Dicynodon rosmarus, Cope, and Rhabdopelix longispinis, 
Cope. The latter he had formerly suspected to be a Pterosaurian, 
but he thought it more likely that it would turn out to be a Rhyn- 
chocephalian reptile. 
He called attention ud four remarkable vertebre from the Creta- 
ceous greensand of ersey, which were characterized by the 
possession of enormous dieser er foramina. e articular ex- 
tremiti r ose, and with scarcely any T layer, so 
that they probably belonged to an immature animal, and were to 
be referred to the sacral or the lumbar region. If they be- 
longed ‘to the latter, they indicated a coossification similar to that 
seen in many birds. That they were not dorsal is indicated by the 
lack of capitular articulations. The pneumatic foramina occupied 
half of the centrum, along its middle, leaving abutments fore and 
aft for the support of the neural arch, which was lost in each one.

as well as contracted upwards ; articular extremity subtriangular, 
with rounded angles and notch for neural canal one-third its vertical 
diameter. Cancellous tissue coarse, but much finer than in Lælaps; 
the dense layer thin. The total length of the four is 174 inches, o 
shortest measuring 4, the other three 4j inches in length.
