41. Lepadocystis^ Carpenter, generic characteristics 
Lepadocystinae^ with oval theca composed of plates arranged 
as follows : 
Basal row, with plates 4, 1, 2, 3. 
Second row, with plates 5, 6, 7, 8, 9. 
Third row, with plates 10, 11, 12, and 14. Plate 13 has been 
elevated sufficiently to be chiefly in the fourth row. 
Fourth row, with plates 16, 17, 18, 19, and 15. Also most of 
plate 13. 
Fifth row, with plates 22, 23, 24, 20 and 21. 
Column obliquely attached at the base, with anal area on that 
side of the theca which has the longest curvature. 
Anal area prominent, between plates 7, 8, 13 and 14. 
Pectinirhombs on plates 1-5, 10-15, 11-17, 12-18, and 14-15, 
with more or less discrete areas of a lunate form, usually deeply 
impressed on the convex margin, and crossed by rather numerous 
dichopores. 
Ambulacra five, reclining upon the surface of the theca and 
terminating usually at, or slightly beyond, the middle of plates 15, 
16, 17, 18, and 19. 
Genotype, Lepocrinites moorei, Aleek. 
The generic term Lepadocystis was proposed by Carpenter, in 
1894, in vol. 24 of the Journal of the Linnean Society, Zoology, on 
p. 10, in the following words: 
Another interesting and geologically earlier form is Lepocrinites 
{Lepadocrinus) Moorei of Meek, from the Cincinnati group of 
Indiana, which differs from L. Gehhardi in having five ambulacra 
and a poreuffiomb on plates 10-15, in addition to those on 1-5, 
12-13, and 14-15. I am inclined to regard these characters as 
of generic value, and would propose therefore to distinguish Meekh 
species by the name of Lepadocystis, 
To this list of pore-rhombs, as given by Carpenter, should be 
added that on plates 11-17, as already stated above. The latter 
had escaped the attention of Meek, owing to the imperfect 
cleaning of this part of the type specimen. 
The anus has been shifted upward and toward the right from 
its archetypal position between plates 7, 8, and 13, so as to come in 
cont/act also with plate 14. In this process, plates 7 and 8 have
