1882. ] CORALS FROM MADEIRA. 217 
the other half the higher orders are not developed. The pali follow 
the ordinary rule, and are before the tertiary septa in all systems 
where the higher orders are fully developed ; and consequently there 
are eleven long, narrow, wavy, very distinct, and well-developed 
ali. 
5 There is a decided endotheca just within the margin, whose edge 
is somewhat inverted ; and it covers some of the pali and occludes 
several interseptal loculi. In other parts dissepiments may be seen 
stretching between the septa. The cost are numerous at the base, 
and are in lines of granules or in faint ridges. Near the calice the 
coste of the larger septa are the most projecting; and all are marked 
with granules, which, in some instances, assume a serpentine arrange- 
meut. There are faint traces of a pellicular epitheca.

From Madeira. 
Subfamily Trochocyathacee. 
Genus Paracyaruus, Milne-Edwards & Haime, 1848. 
PARACYATHUS STRIATUS, Philippi, sp. 
Several specimens of this widely-distributed form, with unlobed 
pali and well-developed cost, are from Madeira. The species is 
common in the Mediterranean and in the Caribbean Sea. 
Subfamily Turbinoline. 
There are four specimens of a simple coral in the collection from 
Madeira, which were dredged at a depth of 30 fathoms in Funchal 
Bay; and they represent three stages of the growth of the species.

The coral is horn-shaped, bent, and has several growth-rings on 
it; it was attached by a narrow circular base, which has broken 
from its support, The calice is wider than the rest of the body, is 
almost circular in outline, and its marginal wall is thin. The axial 
space is wide and deep; the septa are thin, wide apart, and rather 
bent ; they are unequal, very slightly exsert, and do not reach far into 
the calice except in the instance of the larger ones. There are 
several quite rudimentary septa in some parts of the calice; but 
they correspond to cost which are much larger in every respect. 
Omitting these, the septa are twenty-seven in number, and counting 
them, are forty-four in all. The arrangement in cycles is irregular ; 
and there appear to be five primaries only. The margin between 
the septa has a festooned edge; and the interseptal Spaces are 
wide. It is at the lowest point of the concavity of the festoon that 
the minute septa arise. The tertiary septa are smaller than the 
secondaries, and they project well from the wall and reach down 
into the depths of the calice. The septa are rounded above; their 
edge is rather straight within ; and they are sometimes bent; and
