outer lip, nor the ridge on the inner, that is exhibited by 4. subordi- — 
cularis ; while A. syuamosa, although possessing the ridge, does not 
seem to have the groove ; and besides, the cells are in general linear, 
instead of sub-oval or sub-polygonal. 
Locality and formation.—Township of Cayuga. Corniferous Lime- 
stone.

Not S. ¢ubiporotdes (Yandell and Shumard), nor of M. Edwards 
and J. Haime. Polypiers fossiles des terrains paleozoiques, p. 292. 
Since the publication of this species in the Canadian Journal in 
March last, Professor Dana, of New Haven, has informed me that the 
true S. tubiporoides is a much larger form, and is supposed to be an 
Eridophyllum. 1 thought I could identify ours by the description 
given in the work of Edwards and Haime, but it now appears quite 
certain that it is not the same; and also that their fossil cannot be 
the S. tubiporoides of Yandell and Shumard. In order, therefore, to 
avoid confusion, I propose to change the name of this species to 
S. Maclurei. 
In my description, the corallites are said to have a diameter of about 
one line and a half; but, after examining other specimens, I find that 
in the greater number it is more nearly one line. In some of the colo- 
nies, many of the tubes are full one line and one-third in thickness, 
and it was upon these my first statement was founded. 
Sometimes the groups are exceedingly irregular, the corallites 
widely separated and straggling through the rock. 
FavOSITES TURBINATA. 
FavositEs TURBINATA (Billings.) Canadian Journal, March, 1859. 
The description of this species was published in the Canadian 
Journal for March, 1859. At that time the only specimens I had 
seen were from the Corniferous Limestone, but we have now several 
from the Hamilton Group. The species differs from all other favo- 
sites known, in its peculiar mode of growth. The form resembles 
that of a large cyathophylloid coral,—turbinate, the base or smaller
