DovustruL SPECIES. 
Besides the foregoing species of Monticuliporide and 
Bryozoa which were obtained from the hard calcareous 
band of Céte d’Abraham, Quebec, there occur in addition, 
two forms whose generic and specific affinities are still 
doubtful, since the material from which Mr. Weston pre- 
pared the microscopic slides which contains both is some- 
what imperfect and poorly preserved, most of the structure 
of one polypary having been obliterated in the one, and in 
the other case the matrix is very granular, which fact gives 
a granular and obscure aspect to the organism. The spe- 
cimen from which the slide was prepared, was obtained 
also from Céte d’Abraham, Quebec, and the number of the 
slide or section is 2,117. For reference sake the two forms 
are designated A. and B. respectively. 
FORM A. 
GENUS ? — SPECIES — ? 
This form consists of a small, narrowly cylindrical or 
slightly flattened polypary, with one row of rather deeply 
and obliquely situate cells on each side of the median axis 
or line which separates the zoarium into two parts. The 
zoarium measures seven-sixtieths (-116) of an inch in 
diameter, whilst the width of the zocecia or tubes at their 
aperture measures less than 1-100th. of an inch in 
diameter. The polypary is obtusely rounded at one 
extremity—the distal extremity of the zoarium—and the 
cells are inclined at an angle of about 45° to the median axis. 
No evidence of tubule or diaphragms of any sort have been 
observed in the section. The microscopic section shows the 
skeletal parts of the polypary to be fibrous in structure. In 
a general way, this form appears to belong to the family of 
Ptilodictyonide, but its generic and specific affinities are 
still unknown.
