142 The American Geologist. September, 1892 
Remarl's. The unique specimen from wliicli tiie above de- 
scription is made, was discovered by Mr. Charles Beachler, a very 
enthusiastic collector, in whose honor the species is named.

Calyx moderately small, turbinate, dorsal cup about as wide as 
high, gradually spreading to the arm bases, which are formed 
into five very conspicuous lobes, giving to the calj'x, as seen from 
above, a decidedly stellate outline. Plates without ornamen- 
tation, a little concave, except the median line of the radial 
plates, which is obtusely angular. The radial appendages, from 
which the arms are given off, composed of a single series of 
plates. 
Basals rather large, subequal, forming a shallow cup which is 
slightly truncate at the lower end. Radials twice as large as the 
first costals, hexagonal, about as wide as high ; their upper slop- 
ing faces a little larger than the corresponding lower ones. Second 
costals very small and curved like arm plates ; their upper slop- 
ing faces unequal, that toward the outer side of the ray much 
longer and supporting a distichal, the inner one the first arm 
plate. The free rays, which consist of a single series of plates, 
give off the arms at intervals from alternate sides, not from 
opposite sides, as generally in this genus. Interbrachial spaces 
wide, the first plate large, succeeded by two rows of two and 
three plates respectirely, which are followed by disk plates. The 
two outer plates of the upper row curve outward so as to form 
the sides of the lobes. At the anal side the first plate is larger, 
and followed by three plates in the second row, and four in the 
third. Ventral disk depressed, pentagonal; the ambulacral 
regions slightlj' raised above the general plane ; the plates without 
ornamentation, almost flat, and the sutures difficult to see. The 
disk ambulacra are completely subtegminal; the orals apparently 
unrepresented, and the anus is placed at the end of a large tube 
which bends to the posterior side.
