Syringopora burlingi n. sp. 
Plate III, figures 3, 4 
Tubes 1| mm. to 2 mm. in diameter, distant from one another 
about their own diameter, subparallel growth, rarely touching. Numerous, 
often verticillate, transverse tubules, stout, averaging as large as 1 mm. 
in diameter, closely placed, many less than 1 mm. apart. External surface 
covered with multitudinous wrinkled lines of growth. Diaphragms 
slightly concave, not funnel-shaped, four to five in 2 mm., as a rule more 
crowded in the region from which the transverse tubules are given off. 
S. burlingi is easily distinguished from any other species in a 
longitudinal section by the stout, relatively closely set corailites, and thick, 
crowded, transverse tubules, resulting in a closely compact strong corallum. 
The size of the corailites is not very different from 8. retiformis and a 
view of the top might suggest a comparison, but they are more closely 
set than in the latter species, and a longitudinal view makes the differences 
very evident. The corailites are smaller than S. dalmani and the tubules 
more crowded. 
The species is named after Mr. L. D. Burling, who made a collection 
in these Ordovician beds during his time spent on field work for the 
Geological Survey, Canada.

light grey Halysites beds. Beaverfoot range, northeast of mount McMurdo, 
near Golden, B.C. 
Syringopora Columbiana n. sp. 
Plate III, figures 5, 6 
A coral forming a large colony. No specimen is complete, but judging 
from the erect direction of the tubes of one large specimen it grows from 
a small base assuming an upright rather than a spreading form. Long, 
slender tubes f to f mm. in diameter, in some cases diverging slightly, 
mostly subparallel, in some cases contiguous, in some cases about 1 mm. 
apart. Connecting tubules at intervals of from to 3 mm. Ring growth- 
lines not evident, though the surface is frequently undulating. 
A longitudinal section shows the interior not well preserved. It is not 
possible to trace the usual funnel-shaped cups, but little projections inward 
from the walls suggest that they are oblique rather than horizontal. 
S. Columbiana resembles Cannapora junciformis Hall ( S.fibrata Romin- 
ger) in the fineness of its tubes, but differs from it in the smoothness of the 
exterior surface, and the length of the intervals between the transverse tubes 
is from four to five times as great, both of which characteristics tend to 
give it a more slender, delicate form. It differs from S. compada in that 
the tubes are subparallel, and a slight distance apart, not in the perfect 
contiguity exhibited by the latter species. 
Horizon and Locality. Richmond: Beaverfoot. From the Stoddart 
Creek section, Windermere area, and at Harrogate, B.C.
