in one plane, seem referable to this species. The cortex is covered with very long twisted spindles, 
up to 4 mm. in length, very coarsely and regularly warted. The polyps are much retracted 
into depressions among the spindles; they show (a) a low calyx more developed on its lower 
lip, and consisting of spindles longitudinally arranged, sloping upwards at an acute angle; (^) a 
crown of 4 —5 rows; and (r) well-developed triangular opercular points, each consisting- of about 
four pairs of spindles in chevron. 
We are inclined to think that M. ceylonensis should remain distinct from M. ramosa 
as Miss Gordon has emphasised, but that it should in the meantime remain in the genus 
Muricella, and not be referred, as Nutting does, to the new genus Versluysia. 
Previously recorded from Ceylon and by Nutting from Stations 50, 260, 289 and 305.

The features of the genus Anthogorgia are: the strongly projecting tubular verrucse, 
with the absence of chevron-arrangement in the spindles of the verruca wall, the presence of a 
well-defined crown and points on the anthocodia, and the restriction of the spicules to stout 
spindles with compound warts. 
The following species have been described: 
A. divaricata Verrill. < 
A. japonica Studer. 
A. verrilli Thomson & Henderson (1906) (non A. verrilli Nutting). 
A. glomerata Thomson & Simpson. 
A. racemosa Thomson & Simpson. 
A. verrilli Nutting (1910) (non A. verrilli Thomson & Henderson). 
A. atirea Nutting. 
Studer’s A. japoni'ca has not an anthocodial operculum and should be excluded from 
this genus. 
A small damaged specimen of a greyish-brown colour, rising to a height of 4 cm., with 
an average branch thickness of 3 mm. There are some well-preserved polyps, and we are unable 
to refer the specimen to any of the described species. It comes nearest to A. racemosa. 
Its features are the following :• 
(a) the prominent verrucee, rising to a maximum height of 3 mm., have typically a regularly 
arranged spiculation of stout 'tuberculate spindles vertically disposed, dovetailed into one 
another, without hint of chevron, but sometimes with hints of rows; 
(l) the typical operculum consists of a crown and points, two or three rows of horizontals forming 
the crown, while each point in the majority consists definitely of two pairs of spindles 
diverging in chevron fashion. In some cases there is a fifth spindle between the diverging 
bases; in other cases there are three pairs. 
The spicules show a varying degree of roughness; (a) the majority are covered with 
coarse compound warts, very dense in some of the stouter forms, sparser in others; some of
