largest and longest, but they are barely exsert; and the secondaries often have a tertiary 
united to them very low down in the very deep calice, near the rudimentary columella. 
The calicular margin is stout. 
Height ;‘4, inch; breadth of calice ,%-inch. 
The buds are bent slightly; and the smaller ones have three cycles of septa. 
The form resembles Blastotrochus ; but the buds do not fall off, but remain to form 
the tuft-like corallum. It is a genus allied to Smilotrochus, Ed. & H., and Onchotrochus, 
nobis ; but the gemmation and epitheca separate it. 
Much resembling in its calice, except in the thick margin, Cenocyathus anthophyllites ; 
this species, however, has no pali. 
Locality: Northern shores of Mediterranean, below tide-marks. 
Genus BLASTOSMILIA, gen. nov. 
The corallum is compound ; and there are repeated gemmations from the wall of the 
parent corallite, and occasionally from the walls of buds. The corallites are conico- 
cylindrical, long, bent, except the parent; and the calice is circular in outline and deep. 
The wall is thin, and is covered with a granular epitheca, the rudimentary coste being 
only visible close to the calices. The columella is rudimentary, but exists as trabecule 
from the septal ends. The septa are very thin, slightly exsert, not incised, project 
but little into the calice; and the primaries, and sometimes the secondaries, unite 
at the base of the fossa with the small deeply seated columella. There are six systems 
of septa; and the fourth cycle is usually incomplete in some systems. 
The dissepiments are wide apart, and are formed at the bottom of the calice by the 
septal ends becoming oblique and wide and occluding the space below. 
BLASTOSMILIA POURTALESI, sp. nov. (Pl. XLV. figs. 14-17.) 
The corallum has a long parent corallite, with long cylindroid curved buds, curving 
more or less in oblique series. The septa are unequal, the primaries being larger than 
the secondaries; they are also slightly exsert. The coste near the margin are broader 
than the septa; and the margin is unequally circular in young specimens, the intercostal 
spaces bulging out in elegant curves. ‘The septa of the parent are in six systems; and 
the fourth cycle is in all of them; but there are only three cycles in the next in size. 
The columella is small. 
Height nearly 1} inch; breadth of parent calice 3; inch. 
Locality: Mediterranean, from red-coral zone. 
Count L. F. Pourtales, in his admirable description of the Deep-sea Corals (Illust. 
Catalogue, No. iv. p. 21), described and figured a coral, Calosmilia fecunda, Poutt., 
which evidently has the closest alliance with this Blastosmilia. He remarks, after 
describing his species, that the generic affinities are a little doubtful, and distinguishes
