Longitudinal section. This section shows the characters 
of P. lycoperdon, save the smaller or interstitial cells -with 
closely arranged tabule which appear to be wanting: The 
curious oblique funnel-shaped or invaginating diaphragms 
with tabule developed in them at different heights, are 
exceedingly striking and characteristic; some of the 
zoeecia present horizontal and straight diaphragms 
from wall to wall. There are about 72 zocecia in the space 
of one inch, or each zozecium is -0138 inch in diameter. In 
this character this variety comes closer to the smallest 
representatives of the type (P. lycoperdon Vanuxem or P. 
Selwyni of Nicholson), which are 1-70th of an inch in 
diameter.

DipLotryPA QuEBECENSIS, N. SP. 
Zoarium sub-hemispherical, base concave, height about 
two lines, diameter about half an inch. 
Tangential or cross section. Zocecia about 1-60 th. inch in 
diameter, varying from 1-50 th. to 1-75 th. of an inch. In 
shape, the zocecia are polygonal, but often circular, mostly 
in contact, but at times one zocecium is almost completely 
isolated by the presence of interstitial cells, which are 
developed throughout the zoarium but in greater number’ 
in certain portions of it. The interstitial cells vary con- 
siderably in shape, size and distribution, being often 
triangular, hour-glass shaped, and four, five, and even six 
sided at other times. No spiniform tubuli are seen in this 
section. 
Vertical or longitudinal section. The tubes are perpendi- 
cular to the base of the zoarium and regularly disposed. The 
walls are comparatively thick, and especially in the upper 
portion of the zoarium. The zocecia have a few distinct 
horizontal or slightly curved tubule or diaphragms, whilst
