smooth, flat rods, bars and spindles, with projections on the two lateral surfaces 

 only. Spindles are from 012 to 16 mm. long and fi'oni 0048 to 0"19 mm. broad. 

 Clubs reach a length of 0"64 mm. Smooth rods, bars or spindles are from 

 0'06 to 012 mm. long and average 0012 mm. in breadth. 



(h) The stalk spicules are straight or curved spindles and three-rayed forms 

 thickly covered by very prominent rough warts. There are also irregular stars 

 and globular forms, and smooth, flat forms similar to those of the stem except 

 that they have longer lateral projections. Spindles vary from 0"24 to 088 mm. 

 in length and from 006 to 0'16 mm. in breadth. The three-rayed forms have a 

 maximum length of 0"88 mm. while a ray often measures 0'12 mm. in breadth. 

 Smooth, flat forms vary from 006 to 0"24 mm. in length and have an average 

 breadth of 002 mm. 



Colour — Stalk brownish in lower part, becoming gradually lighter till it is 

 greyish in upper part ; the stem gradually becomes pinkish-grey ; principal 

 branches almost a salmon-pink ; polyps pink or grey, according to the 

 spicules ; tentacles a translucent grey.

The colony is characterised by its roundish polyparium, its regular outline, 

 its distinctly flattened lower branches, and the fact that the polyps are all or 

 nearly all on the surface. It presents a fairly compact appearance owing to 

 the method of branching. The colony is about 4 cm. high and about 3o cm. 

 broad. 



The stalk is short, [^but its actual length cannot be given, as the lower 

 part is evidently torn away ; its upper part is covered by a collar formed by the 

 reflexed flattened branches. It is granular in appearance and speckled red. 



The polyparium is compact and rounded, showing a slight flattening and 

 tending to develop into two main knob-like portions. At the upper end of the 

 stalk three flattened branches are given off", two of which have very wide 

 bases and may be called leaf-like, while the third has a cylindrical stalk and a 

 flattened upper portion resembling an umbrella turned inside-out. Above this 

 the stem divides into two main portions which form the bases of the knob-like 

 processes above-mentioned. From these branches are given off", which divide 

 into smaller l>ranches, which in turn give rise to the small flattened twigs from 

 which the polyp-stalks arise, thus bringing all the polyps to the surface and 

 giving the colony a spiny appearance, due to the projecting Stiitzbundel si)icules. 



The polyps are placed on short stalks at an obtuse angle, and are arranged 

 in small groups of four to seven individuals ; several groups may be closely 

 pressed together, giving the appearance of a large group with many more in-
