sides of every plate of the proboscis from the second brachials to 
the very top; some specimens of the proboscis have one or more 
intercalated plates near the lower end, and all are more or less 
twisted. There is a bifurcated proboscis in the collection which 
has five series of plates below the bifurcation, and three intercalated 
series at the bifurcation, so that each branch has four series, which 
we have illustrated. It is an abnormal specimen that may have 
resulted from an injury. The column is small, pentagonal, tuber- 
culated and bore cirrhi to a greater or less extent. 
This species was collected in the Upper Coal Measures, at Kan- 
sas City, and the specimens are in the collection of Wm. F. E. 
Gurley, of Danville, Illinois.

flate [I[l., Fig. 1, natural size as it lies upon a slab. 
This species is distinguished from A. magnificus, by having pro- 
portionally a much smaller and a smooth proboscis. The calyx is 
bowl-shaped ; column pentagonal; basals of moderate size; subra- 
dials convex and extending half the hight of the calyx; first radials 
wider than high; first and second brachials and arms as in A. 
magnificus but proportionally smaller. The proboscis is much 
smaller in proportion to the size of the calyx than it is in A. 
magnificus, and the exterior of the plates is smooth, though the 
respiratory fissures in the two species are alike. This species is 
thus founded upon the surface character of the proboscis, and the 
proportionally larger calyx when compared with other parts of the 
body and arms. 
These Kansas City fossils were collected in blue clay, where they 
were remarkably well preserved; but some specimens were injured 
by the collectors, who undertook to wash them when no water should 
have been applied. Many of the specimens were found with the 
heads downward and the arms spread out, leaving the base of the 
calyx upward, with the strong proboscis pressed to one side as 
shown in the illustration of this species. 
From the Upper Coal Measures of Kansas City, and now in the 
collection of Wm. F. E. Gurley. The specific name is in honor 
of Sidney J. Hare.
