*Through the kindness of Prof. Stuart Weller, of Chicago, I was informed that our Fusu- 
lina cylindrica, described by Fischer in 1837, was described by Say, under the name of Miliolites 
secalicus, from near the Platte river on the ‘Missouri river, in Nebraska, in Long's Expedition, 
published in 1823, p. 151, foot-note. As it is impossible to confound it with any other species in 
the region, it gives the specific name secalica (Say) priority. 
tr=rare, rr=very rare, c=common, a=abundant, aa=very abundant.
