This is sometimes reddish ; but this should not be made a 
specific character,for at Naples Filisparsa tubulosa , Entalophora 
proboscidea , Idmonea concava , &c. are found both red and 
white. 
Loc. Pliocene: Ficarazzi (Sicily), Castrocaro. Living: 
Northern Seas; Naples, on seaweed, from 2 fathoms and also 
20-30 fathoms ; Adriatic (Heller).

The specimens I have from Naples are strap-shaped or 
formed of elongated lobes. The tubular cells are very long, 
with a tendency to form in series ; the ends of the tubes are 
free. This is the T. serpens of some authors; but there 
does not seem any hard and fast line by which serpens can be 
separated from phalangea , which also passes into jlabellaris.

The zooecial tubes are about 0T6 millim., which is smaller 
than in the northern form.

Colony orbicular, 10-15 millims. in diameter, with zooecial 
tubes, indistinctly radial, short in the centre, very long and 
raised towards the edge; no adventitious tubuli; ooecial 
apertures («) small, not much raised. In the centre is often 
a small, round or triangular, open space; and from this can 
be seen that the growth is similar to Tubulipora jlabellaris ; 
and it might with equal propriety be called Tubulipora or 
Diastopora , though, in fact, it would seem most reasonable to 
call it T. jlabellaris, var. latomarginata. I have specimens 
confluent; but this is, perhaps, accidental, arising from inde¬ 
pendent colonies joining.
