contact with the sides of plates 18 and 19, instead of touching 
them only at their lateral bases. 
42. Lepadocystis moorei, Meek 
(Plate 5, Figs. 1 A, B, C, D) 
The type of Lepadocrinites moorei, Meek, is preserved in the 
Museum of Earlham College, at Richmond, Indiana. It was 
found by H. C. Balls, a student at the college, and submitted by 
Prof. Joseph Moore to Meek. Through the courtesy of Prof. 
A. D. Hole, I was permitted to examine this type. 
The following is an attempt at an independent analysis of the 
plate system of the type, which is intended to show where the

the ray is indicated. The natural size of the specimen is indicated by an outline

details are clearly defined and where they are imperfectly exhib- 
ited by the type specimen. This diagram differs but slightly 
from that presented by Bather in his volume on the Echinoderma, 
forming Part III of Lancaster’s Treatise on Zoology, published in 
1900. 
In this diagram, the character of the surface ornamentation, 
consisting chiefly of parallel lines radiating in different directions, 
is indicated, wherever preserved. The ornamentation of plate 13, 
and of plates 15 to 19, probably was very faint or practically 
absent. The outlines of plates 11 and 17, and those of the adja- 
cent parts of plates 5, 6, and 12 are so poorly defined that they can 
not be indicated with exactness. The surface ornamentation of
