694 A. W. WATERS ON FOSSIL CYCLOSTOMATOUS 
The dilatation of the fasciculi at the summit occurs in these 
specimens only where the fasciculi are beginning to branch. 
This differs from Fascicularia tubipora, Busk, in not having the 
fasciculi united by what Busk calls “horizontal tabular concentric 
lamin ;” these are probably represented by the small multitubular 
connexions, and in a specimen of Fascicularia tubipora collected in 
Rametto, near Messina, Sicily, from the Pliocene, there is, besides 
the larger “laminz,” an occasional connexion like that of F. ramosa. 
F’, tubypora also occurs from Napier, New Zealand. 
The genera Fascicularia and Fasciculipora seem most closely 
allied, 
Loc. Mt. Brown beds (Upper Eocene of Hector), New Zealand, 
River Murray Cliffs.

For synonyms see Hincks’s Brit. Mar. Polyz. p. 473; but as to 
Discocavea aculeata, dOrb., I am in doubt. Discoporella echinulata, 
Rss., Die foss. Polyp. des W. Tert. p. 50, Taf. vii. fig. 6; Manzoni, 
I Brioz. foss. del Mioc. d’Austr. ed Ungh. p. 15, pl. xiv. fig. 56. 
Specimens from Muddy Creek, Murray River, and Waurn Ponds 
correspond most closely with a simple colony from Naples. 
Ineach case the zocecial openings are about 0-1 millim. to 0-2 millim. 
in diameter, and in the Naples and River-Murray specimens the 
central cancelli are rather over 0:07 millim., while the interradial 
cancelli are 0:06 millim.; but in the Muddy-Creek specimen the 
central and interradial cancelli are of about the same size, viz. 0°06— 
0°07 millim. | 
In the Muddy-Creek specimen I am able to see a distinct row of 
spicular denticles a short distance down the zocecial tube. This 
small colony of about 2 millim. diam. is not well preserved, whereas 
those from Murray Cliffs are less damaged, and are about 5—6 millim., 
and the radial arrangement of the zocecia is more distinct. A specimen 
from Waurn Ponds may bea variety. The zoarium is 10 millim, in 
diam., and the zoccia are 0-07 in regular uniserial distinct rows 
towards the centre. 
In the central part of the Naples specimen there is at the junction 
of the wall of each opening a small protuberance reminding us of 
the “ Spiniform corallites,” of Prof. A. Nicholson (‘Structure of 
Heteropora,” &c. Ann. & Mag. Nat. Hist. 1880, p. 14, fig. 4). 
Loc. Miocene: Eisenstadt and Morbisch (1/.). Pliocene: Crag, 
Italy (Reggiano in the Zanclian, Astian, Sicilian, and Saharian of 
Seguenza); Scotch Glacial deposits (Geckze). Post-Pliocene of 
Canada (Dawson). Mt. Gambier, Bairnsdale, Muddy Creek, Murray 
River, Waurn Ponds. Living: European seas generally. 
28. LicHENOPoRA RADIATA, Aud. 
The zocecial opening in specimens from the Mediterranean and 
also in the fossils is 0:07-0:08 millim., and in the specimen from 
Adelaide is only a trifle smaller.
