232 The American Geologist. October > 1903 - 
Dichopores on plates i, 12 and 14 not shown at the surface 
as thcv are deeply situated within small oval pits each with a 
rim highly elevated above the surface of these plates. Those 
on plates 5, 18 and 15 show the dichopores with the excavation 
deepest orally and are here delimited by a crescentic lip. About 
eight folds in each half -rhomb. 
Hvdropore conspicuous, situated on a small piece (plate 
21), placed above and between plates 18 and 13. No madre- 
porite discernable here. 
Anal pyramid small, not strongly elevated, composed of 
six pieces, but made quite prominent by the protrusion of the 
bounding margins of the thecal plates 7, 8, 13 and 14. 
Column comparatively stout and, as is usual in cystids, com- 
posed of thick segments near the theca. Length unknown. 
Formation and locality. — A very common species in the 
quarries and elsewhere near Keyser, West Virginia. Several 
hundred specimens have been seen. The first specimen was 
dug up near Judge Alkire's house by Mr. Frank Hartley of 
Cumberland, Maryland. It is associated with Sphaerocystites 
multifasciatits, S. globularis, and Pscudocrinites gordoni, to- 
gether with the above, these being the four common species of 
the cvstid beds of the lower Manlius formation about Keyser. 
It gives the writer pleasure to name this species for its discov- 
erer in recognition of his enthusiasm and untiring efforts in the 
unearthing of many new Siluric and Devonic species of West- 
ern Maryland.

Jack-el's* definition of Sphaerocystites cannot be accepted 
as it is based not on the genotype 6". multifasciatus, but on 6".
