342 The American Geologist. 
June, 1905- 
the land tortoises now living in North America have 
descended from Hadrianus. They have been separated 
under the name Xerobates, on account of the symphysial 
ridge of the upper jaw. During the White River and John 
Day epochs there existed a few species of the genus Style- 
mys. An imperfect skull, referred to ^. nebrascensis, nwo 
belonging to Princeton University, displays the same pecu- 
liar structure. There are also various resemblances be- 
tween the shells of the living and the extinct forms ; so that 
a real relationship is suggested. 
ON THE LANSING MAN.*

In the latter part of March of the present year a brief 
newspaper note announced the discovery of a human skull 
and other bones in a deep excavation made by Mr. Martin 
Concannon, for the purpose of storing vegetables and dairy 
products, in the vicinity of Lansing, Kansas. The excava- 
tion had been begun more than a year previously, but was 
not completed until in February, 1902, at which time the 
skeleton was discovered by the two sons, Messrs. Michael 
T. and Joseph H. Concannon, near its extremity, or about 
sixty-nine feet from the entrance. Occasional bones, prob- 
ably of other animals, had been discovered during the pro- 
gress of the work, and not a great deal of interest was ex- 
cited by the exhumation of the human bones. They were,, 
however, for the most part, laid aside, though many frag- 
ments of small bones had been cast out with the excavated 
material. It was not until the latter part of March follow- 
ing that Mr. Michael Concannon showed a part of the man- 
dible to a newspaper reporter, who published the first brief 
notice of the discovery. This notice attracted the attention 
of Mr. M. C. Long, of Kansas City, who immediately visited 
the site of the discovery in company with Mr. Butts, a civil 
engineer, of Kansas City, who secured such of the bones as-
