are smooth, flattened, spindle- to star-shaped forms. The pointed spindles 

 measure up to 0'9 mm. in length and 0'15 mm. in breadth. 



(/*) In the stalk there are spindles, three- and four-rayed forms, thickly 

 covered with more or less regularly arranged rough warts, some of which may 

 reach a height of about 0-08 mm. The spindles vary from 0-48 to 18 mm. in 

 length and from 009 to OiS mm. in breadth, and the three-rayed measure up 

 to 0'9 mm. in length. 



Colour — The stalk is whitish ; the main stem yellowish-white ; the main 

 branches more deeply tinged with yellow than the stem ; the smaller branches 

 and twigs are salmon-pink ; the polyps white, spicules and bodies alike.

Dendronephthya grandiflora, Henderson. 



The colony is large, very compact, much flattened in one plane, and has a 

 regular oval outline, with the long axis of the oval nearly perpendicular to the 

 stem. It measures 8"5 cm. in height and 8 cm. in maximum breadth. 



The stalk is short, 

 thick and fairly rigid, 

 wrinkled and ridged, gran- 

 ular in appearance, and 

 gives oft' a few stolons. It 

 measures about 2 cm. in 

 height, about one-fourth 

 of the total height of the 

 colony. 



The polyparium is 

 large, compact, regular in 

 outline, oval in shape, the 

 long axis being almost at 

 right angles to the stem. 

 From the lower part of the 

 stem a number of branches 

 are given off", and almost 

 directly above this the 

 main stem gives off" in one plane, opposite one another, two large branches 

 which rise obliquely at an angle to the stem. The stem rises for a short distance 

 and then divides into two main mutually divergent portions or branches in the 

 same plane as the lower. These four main branches give off in close proximity 

 on all sides numerous branches which by repeated divisions give rise to the flat- 

 tened twigs on which the polyp-stalks arise. The lower branches are flattened.
