Unrecorded Species of Fossils. 99 
may be readily distinguished from the other two species, 
and on this account has had the varietal designation affixed. 
Locality. Cote d’Abraham, Quebec City, Quebec. 
Collectors —H. M. A. and N. J. Giroux, 1888. 
Micro Sections.—2,110 and 2,115. Prepared by Mr. T. C. 
Weston. 
DicRANOPORA PARVA, N. Sp. 
Length of the only specimen (fragment) examined: 175 
inch ; breadth, ‘05 of an inch. There are from six to eight 
rows of cells across the polypary which are obliquely dis- 
posed in lines, so as to give to the zoerium a quincunxial 
arrangement which is characteristic and evident. Between 
the cell apertures, whose margins are somewhat thickened, 
are seen low depressed and indistinct lines which give a 
slightly longitudinal aspect to the rows of cells, besides the 
oblique or quincunxial disposition. This form appears to be 
distinct from those described by Mr. Ulrich from the 
Cincinnati group of Ohio, and the name JD. parva is here 
suggested for this form. f 
Locality.—Gagnon’s Beach, near the boundary between 
Matanne and McNider Townships, Quebec. 
Collector.—T. C. Weston, 1887. 
PRASOPORA LYCOPERDON, Vanuxem var. SELWYNI, 
N. Var. 
Zoarium sub-hemispherical, massive, about half an inch 
in diameter and the same dimension in height; tubes 
erect, prismatic. 
Tangential or cross-section. This section exhibits the 
characters and general features of the genus Prasopora, 
Nich. and Ether, jr. The zocecia are polygonal however, 
and in close contact with one another, there being 
only an occasional interstitial cell developed between the 
zocecia. This almost total absence of interstitial cells, so 
prominent and characteristic in typical examples of Praso- 
pora lycoperdon, Vanuxem, (=P. Selwyni, Nicholson), from 
the Trenton formation of Canada and the United States, 
differentiate the Quebec species or variety from the typical 
species.
