Arachnophyllum luxurians, Edw. and Haime, 
(Brit. Fos. Cor. t. 69, fig. 2, p. 292. Siluria, 
2nd ed. pl. 39, fig. 6. A. ananas, Linn. (in 
part). Lonsdale, Sil. Syst. pl. 16, fig. 6. 
Siluria, 2nd ed. Foss. 53, fig. 6). There is 
no doubt this is the chief coral intended by 
Linneus, but as he included more than one, 
the A. ananas was described by Lamarck 
from the other species. 
Arachnophyllum, McCoy (Strombodes, Milne 
Edwards). McCoy's genus was certainly 
described shortly before or immediately after 
Milne Edwards’ first description of the ge- 
nus; and it seems hardly worth while to 
revive the doubtful genus of Schweigger, 
and displace a most excellent and graphic 
name for it. 
Arachnophyllum typus, McCoy (Milne Ed- 
wards, t. 71, fig. 1, as Strombodes, Siluria, 
2nd ed. Foss. 52, fig. 6). S. typus, diffluens, 
Murchisoni, Phillipsi, and Labechii, all are 
varieties of one common species. 
[Strombodes Wenlockensis, McCoy, is a Lons- 
daleia, Edwards, and is a common mountain 
limestone coral introduced by mistake; it 
never came from the Wenlock localities, 
J. W.S. 1867] 
Syringophyllum, Edwards and Haime (Sar- 
einula, Linn.in part). The projecting edges 
of the cups are the inner wall (endotheca), 
the interstices being filled by the coronate 
septa, and there are no bounding walls to 
the separate corallites—they are fused to- 
gether as in modern reef-corals, 
Syringophyllum organum, Linn. (Sarcinula, 
Lonsd. and Goldfuss, Pet. Germ. t. 24, fig. 
10). More common in the Lower Silurian 
rocks. (See Milne Edwards, t. 71, fig. 3, 
and Siluria, 2nd ed. Foss, 29, fig. 4.) 

a. 336, Dudley, F. C. is fig. 
2a in M. Edwards’ Mono- 
graph; a. 678 shews the 
buds well. 
b. 716, Dormington, Wool- 
hope; a. 361, near Aymes- 
try, MéCoy’s figure; a. 363, 
Dudley, F.C. as Murchisoni. 
From Shropshire or N, 
Wales. 
No specimen; but should 
be obtained from Dud-
