7. Nidalia splendens n. sp. (Plate I, Fig. 7; Plate VI, Fig. 9; Plate XXV, Fig. 8). 
Stat. 251. 5°28'.4S., 132°o / .2 E. 204 M. Hard coral sand. 1 Ex. 
A very handsome, approximately cylindrical colony, standing rigidly to a total height of 
10 cm. There is a very short sterile stalk of about 2 cm. in height, and with a diameter of about 
the same. The polyps arise all round, but are distant from one another, a common vertical 
interval being 1 cm. The diameter of the stem about the middle of the colony is 1.3 cm. The 
calyces, 8-lobed at their margin, stand out very prominently to a height of about 5 mm., and 
are mostly directed upwards. The retractile upper portion of the polyp is when fully expanded 
about 4 mm. in height. As regards colour, the stem is creamy white and this is continued on 
the lower portion of the calyx; the rest of the calyx is coral-red, and the same is true of the 
retractile portion of the polyp, except that the tentacles are white. Elongated triangles of reddish 
spicules extend for some distance up the dorsal surface of the tentacles. Some of the polyps 
show numerous ova. The spicules include: — ( a ) stout colourless spindles with numerous very 
prominent warts, both simple and compound and often interlocking (0.4X0.06 mm.); ( b ) longer 
narrow red and colourless spindles with fewer warts (0.5X0.03 mm.); (c) spindles with warts in 
zones (0.3X0.06 mm.); ( d ) numerous small irregular and approximately spherical forms; and 
(c) a few quadruplets. 
Genus Metalcyonium. 
1. Metalcyo 7 mim capitatum Pfeffer. 
For description see: 
PFEFFER, Zur Fauna von Slid Georgien. Jahrb. Hamburg Wiss. Anstalt, 1888, VI, p. 50.

Stat. 213. Saleyer. Reef. 1 Ex. 
An unsatisfactory small specimen of a dark brown colour shows a short sterile stalk and 
a lobed head, the total height being 12 mm. It has not the spiculation of a Sarcophytum, 
Sinularia, or Lobophytum, but agrees on the whole with Pfeffer’s Metalcyonuun capitatum. 
Almost all the spicules are somewhat rod-like spindles, of variable breadth in proportion to length, 
bearing not crowded, blunt or more tapering prominences. Two or three four-rayed forms were 
seen on the slide. There is no hint of dimorphism, but the specimen is poor. 
Previously recorded from South-Georgia. 
Genus Lobularia. 
We propose to revive Savigny's genus Lobularia which has had a chequered history. 
By Klunzinger and others it was merged in the genus Alcyonium, from which it was again 
separated by Wright and Studer. But their view was not homologated; thus May regarded 
Lobularia as synonymous with Alcyonium. 
No doubt the two genera are very closely allied, but it seems to us to be convenient 
to revive the genus Lobularia for those Alcyonium-like forms whose spiculation mainly consists 
of a multitude of small double-clubs or double-spheres, generally with a waist. Also characteristic 
are very minute finger-biscuit-like forms.
