82 BRITISH PALAOZOIC FOSSILS. [ Zoopuyva. 
Owing to the fissiparous generation, the adjacent tubes have only one common wall, and a rough vertical 
fracture always exposes the inner cavity of the tubes, instead of the external walls as in Stenopora or Favosites. 
CH#TETES CAPILLARIS (P/ill. Sp.) 
Ref. and Syn.—Favosites capillaris Phill. Geol. York. V. 2. t. 2. f. 3, 4, and 5. 
Sp. Ch.—Corallum forming rounded masses of three or four inches in diameter, composed of slightly diverg- 
ing prismatic tubes, opening at right angles to the surface, averaging fourteen in the space of two lines; 
diaphragms at nearly equal heights in adjacent tubes, and usually a little more or less than the diameter of the 
tubes apart. 
The very small size of the tubes separates this species from the C. septosus. 
Position and Locality —Carboniferous limestone of Kendal, Westmoreland. 
CH#TETES SEPTOSUS (Lem. Sp.) 
Ref. and Syn—Favosites septosus Flem. Phill. Geol. York. V. 2. t. 2. f. 6, 7, and 8. 
“Sp. Ch.—Corallum forming very large tuberose masses, composed of radiating cell-tubes, averaging seven 
or eight in two lines; walls thin, diaphragms at very irregularly unequal heights, in the adjacent tubes, varying 
from one third to nearly twice the diameter of the tubes apart ; fissiparous development of the young tubes very 
frequent and easily observed ; boundaries of the cells coarsely granulated on the surface. 
One very large specimen of irregular growth from Kendal has on some parts of the undulations the cell- 
mouths oblique, as in the F’. spongites, and only five or six in two lines, with the boundary ridges strongly 
tuberculated, other portions of the same mass shew the usual size and direction of the cells; the specimens of 
luxuriant growth seem to have the diaphragms at the most unequal distances, while the more stunted groups, 
which have grown in a regular manner, incrusting a level surface, seem to have the diaphragms at as equal a 
distance and as nearly at the same level in adjacent tubes, as in the Favosites capillaris of Phillips, which may 
thus prove to be an extreme variety of the present species. 
Position and Locality —Forms great masses in the carboniferous limestone of Derbyshire, and Kendal. 
Genus. STENOPORA. See page 24. 
STENOPORA INFLATA (Kon. Sp.) 
Ref. and Syn.—Calamopora inflata Koninck, Anim. Foss. t. A. f. 8. 
Sp. Ch.—Corallum usually forming irregularly tumid or hollow lobulated masses, one or two inches long, 
and usually under three quarters of an inch in diameter; composed of an outer layer, about one-third of a 
line thick, of subequal prismatic tubes, perpendicular to the surface, averaging from twenty-one to twenty- 
two in one line; interior of the tubes cylindrical. 
Owing to the extreme minuteness of the structure of this very distinct coral, I am unable to see all the 
generic characters. It has no relation to the Calamopora dentifera, as M. de Koninck seemed to think, 
being far more minute in structural details. The hemispherical granules of the surface he figures and 
describes are the casts of the cylindrical interiors of the tubes. I have identified the English specimens 
with authentic Belgian examples from the author. 
Position and Locality—Abundant in the carboniferous limestone of Kendal, Westmoreland. 
STENOPORA TUMIDA (Phill. Sp.) 
Ref. and Syn.—Calamopora tumida Phill. Geol. York. Vol. II. t. 1. f. 25. 
Sp. Ch.—Corallum forming cylindrical, irregularly tumid branches, dichotomising at an angle of about 
40° to 75°, composed of close, nearly equal tubes, averaging seven to eight in the space of one line, 
apparently cylindrical within, prismatic without, nearly vertical in the central part of the branches, abruptly
