Observations on Three Kinderhook Fossils. Among the fossils 
described as Kinderhook species, none are prettier or more instructive 
than Dr. White’s coral, Zaphrentis calceola. More correctly, this is 
White and Whitfield’s species. The authors of this species obtained 
the type specimens at Burlington, la., from the base of the Burlington 
limestone and the underlying Kinderhook beds. Afterward Prof. 
Broadhead found this fossil in the Chouteau limestone at Sedalia, Mo., 
and sent specimens of it to the National Museum, where they were ex¬ 
amined by Dr. White and one of them figured in Hayden’s 12th annual 
report of the survey of the territories. 
We have found this beautiful little polyp ranging through three 
quite distinct formations and undergoing in its ascent some noticeable 
changes. The first examples we collected were from the lower Bur¬ 
lington limestone at Louisiana, Mo., about ten feet from the base of 
this division. The specimens from the soft white cherts are small and 
flattened while those from the limestone are somewhat more robust and 
less compressed. 
About eight years after our first acquaintance with this cyathophyl- 
loid we discovered a very much weathered outcrop of about three feet 
of the very base of the lower Burlington group; and, among other 
peculiar fossils, we picked up two grotesque looking examples of Zaph¬ 
rentis calceola, somewhat larger than the limestone specimens above, 
strongly wrinkled, very much flattened and the point (base) in one, 
directed backward* contrary to the outline of the typical specimens. 
Four miles east of Curryville, Mo., in an outcrop of the upper Chou¬ 
teau limestone associated with Michelinia placenta, is a very small, 
wrinkled and flattened variety of this interesting little Zaphrentis. In 
the same formation at other localities in the western part of this
