Unrecorded Species of Fossils. 101 
the interstitial cells have more numerous and horizontal 
diaphragms developed. 
Norte. The paucity of tubuli in the specimen examined 
may be due to its state of preservation or fossilization, as 
the few that are seen in the zoecia are only faintly visible 
in the coarsely crystalline calcite which fills the tube. No 
spiniform tubuli are seen in this section. 
This species is most nearly related to Diplotrypa Milleri, 
Ulrich, but differs therefrom in possessing much fewer 
diaphragms, both in the zocecia and in the interstitial cells. 
It differs also from. D. Whiteavesii, Nicholson, D. Petro- 
politana, Pander, D. regularis, Foord, and D. infida, Ulrich, 
in possessing no spiniform tubuli.

Monorrypa INcERTA, N. Sp. 
Zoarium, small, sub-cylindrical or irregularly elongate 
sub-spherical, height, -25 inch; longer diameter, 375 inch ; 
shorter diameter, °25 inch. 
Tangential section. In tangential sections, the zocecia are 
seen to be regularly polygonal of uniform size, and 
apparently of one kind only. The walls around each are 
clearly visible and are only moderately thickened. Occa- 
sionally a smaller zocecium is developed between the larger 
ones, but appears to be only an immature zocecium and 
differs in no respect from the larger or proper zocecia. 
There are no interstitial cells at all. The other generic 
characters are also evident. 
Longitudinal section. This section exhibits the uniform 
prismatic character and regular size of the tubes. Dia- 
phragms are tolerably numerous and straight, whilst at 
times they have a decided curvature. These are distant 
from each other one tube diameter or thereabouts. 
The zocecia are -0156 inch in diameter, or number 64 in 
the space of oneinch, as measured both in the tangential 
and longitudinal sections.
