a 
cun&e empty. As I know Trochocyathus only by figures, it may be that the tubes of 
its basis require another explanation than I have given, but, however, it cannot be 
considered as having ”tubercles” of the same kind as Schizocyathus or Stenocyathus.

This species varies much as to its columella, which in some is entirely absent, in 
others abundant. The compound corals generally do not arise through gemmation. 
The young have attached themselves on the surface or epitheca of the old, as may 
be easily observed by cautiously removing one of them from its base, when they are 
seen to be in no intimate connection with the subjacent coral. It cannot be placed in 
the genus Coelosmilia, as M. EbwaARrRps expressly states that none of its species has a 
columella. It may be that the presence or absence of that variable part of the coral 
cannot weigh much, but when on the other hand the genus Parasmilia is characte- 
rized as being provided with a columella and PoUrTALES himself says that his speci- 
mens have one, it is best to follow the precedence of M. Epwarps. The genus Cocno- 
smilia of POoUrRTALES belongs also, according to my opinion, to Parasmilia as there is 
no other distinctive character besides that of its propagating by buds.

Off Anguilla in 200 fathoms (Gois). 
Ås there is only one specimen I with some diffidence place it in the genus 
Parasmilia. It is broadly affixed to what seems to be a fragment of another speci- 
men of the same species. Length 10 millimeters, breadth of calicle in one part Y 
millim., in another at right angles to the first 8 millim. There is no epitheca, the 
wall is densely covered with small tubercles, which are arranged in regular longitu- 
dinal costal lines in the vicinity of the calicle. Septa, especially those of the first order 
highly exsert, thin, lamellar, with entire edges and the lateral surfaces ornamented by 
perpendicular rows of small tubercles. The septa are in six systems, of which four 
systems consist of five cycles and two opposite systems of only four cycles of smaller 
size. The columella is composed of a few twisted papillr, four of which are detached 
and placed opposite the interior ends of the secondary septa so as to resemble paluli.
