Halysites catenularius, Linn. (Catenipora es- 
charoides, Siluria, 2nd ed. pl. 40, fig. 14, 
Goldfuss, Pet. Germ. t. 25, fig. 4). The 
commonest of common fossils, in every 
region where Upper Silurian is known. 
Arctic circle, &e. 
Halysites, var. labyrinthicus, Goldfuss, is only 
a variety with very large tubes. 
Syringopora, Goldfuss. This is perhaps the 
extreme form which could be taken by 
Millepores, the tubes or corallites being 
absolutely separate except at the creeping 
base. They throw out lateral appendicles 
which unite and help to support the reti- 
cular mass. The base is known as Aulopora, 
Goldfuss. 
Syringopora fascicularis, Linn. (S. filiformis, 
Lonsd.? Goldfuss, Pet. t. 38, fig. 6, Milne 
Edwards, t. 65, fig. 1), the most slender 
tubed of British Silurian species. Aulopora 
tubeformis, Lonsd. Sil. Syst. (Siluria, 2nd 
ed. pl. 40, fig. 12, pl. 41, fig. 8). 
Syringopora bifurcata, Lonsdale, S. reticulata, 
Sil. Syst. t. 15 bis, f. 11 (Siluria, 2nd ed. pl. 
40, figs. 10, 11). A very large-tubed species, 
the largest indeed, and with branches most 
remote. Siluria, 2nd ed. Foss. 19, figs. 
2, 4, 5. 
Syringopora serpens, Linn. (M. Edw. t. 65, 
fig. 2). Aulopora serpens, and conglomerata. 
Lonsd. Siluria, 2nd ed. pl. 41, figs. 6—9. 
ZOANTHARIA RUGOSA, 
M. Edwards and Haime. 
The cup and star-corals of the Silurian rocks 
are found to have more of the character of 
the Tabulata than any recent reef-building 
or cup-corals; and as a very remarkable 
character, the number of the septa is either 
four or a multiple of four, a character only 
found in the Alcyonarian Zoophytes of the 
present seas (Edwards and Haime).
