ral anastom Vlmost immediately above the lïrst branch the main stem is rather abruptly 



ide and gives off numerous lateral bram hes which are irregularly spaced and 



compound and anastomose through their branchlets with other branches, forming a loose 



and irregular network of very delicate texturc. Many <>f tin- luanchlets are nol more than 



.; mm, in diameter, while the larger branches are scarcely i mm. thick. The calyces are 



alarlv but rather thickly distributed on all sides ol the terminal twigs, and on three sides 



<>t" the othei j average a little more than i mm. apart from summit to summit. 



1'Ih- individual calyces are small but prominenl for the genus, being in the shape of a 

 dome averaging about .8 mm. in height and 1.5 mm. in diameter al base. The margin is 

 surrounded by eight lobes and the walls are provided with eight rather indefmite Iongitudinal 

 rihs which art- also seen in the general coenenchyma as rude Iongitudinal corrugations resembling 

 the bark of a tree. There is a superficial layer of small oval spicules and minute doublé heads 

 in the calyx walls, beneath which are larger regular spindles. The polyps are complet* ly 

 retracted and much flattened or disk-shaped in retraction. They are provided with a rather 

 with the spindles arranged en chevron on tentacle bases. There are rather 

 narrow Iongitudinal bands of spindles on the dorsal surfaces of the tentacles. 

 ["hè axis is the typical one as described for the genus. 



Spicules. These differ materially from other forms in this genus. There is a superficial 

 incomplete layer of quite small doublé heads or dumb-bell-shaped forms under which is a much 

 thicker layer of comparatively large spindles, often curved, with thick-set verrucae arranged in 

 ilar whorls.

Color. The colony is a very light grayish brown. 



General distri but ion. Type locality. Andaman Islands, Indian Ocean; also from the 



idives. Although much more delicate that the type described by Thomson and Henderson, 



this form agrees well with that species. The describers speak of spicules which they call 



■doublé clubs", but their measurements show that they are doublé heads, as the term is used 



in the present work. "Stelfate forms" would appear when doublé heads were viewed end on.
