The diameter (if the ,st(Mu is 4 miii. near the base, Ijiit iliiuiiiishesfiraihially 

 to 3 mm. near the tip. The coenenchyraa is thick ; the general colour of the 

 colony is pale yellow ; but the tips of the verrucae and the anthocodiae are 

 white. 



The present specimen agrees in detail with the last, except in the nature 

 of the verrucae (cf. figs. 84 and 85). 



Locality. — Off and east of Cape Morgan, 36 fms. Bottom : stones. 



A beautiful, complete, simple colony, 22'5 cm. in length ; the 

 coenenchyma is moderately thick and densely granular ; the general 

 colour is a bright orange-yellow ; but the tips of the verrucae and tlie 

 anthocodiae are white, and there are also white streaks throughout the 

 coenenchyma. 



The polyps are distributed in two lateral, longitudinal series ; the bare 

 median tracts are fairly well defined. The number of rows in each series 

 varies from two to four. The verrucae are sub-cylindrical, directed 

 upwards, and adpressed to the stem (fig. 86). The members of two adjacent 

 rows alternate with one another so that the tip of one verruca is on a level 

 with the base of the next higher in the adjacent row. The verrucae are 

 about 1'25 mm. in height and 0'75 mm. in diameter. Near the base they 

 are much smaller, more distant, and a few are even sunk into pits in the 

 coenenchyma. The anthocodiae are white ; the tentacles are short, but have 

 a dense aboral armature. 



The canal system is typical and well developed ; the two main canals are 

 easily seen when a piece of the coenenchyma is detached. 



The axis is slender, flexible, but very calcareous ; the surface is marked 

 by longitudinal striae. 



Lvcality. — Umhloti Eiver mouth, N. by W. half W., 8| miles, 43 fms. 

 Bottom : sand, shells, and hard ground. 



A small, complete colony, 15"5 cm. in height; is almost identical with the 

 last specimen. 



The following diiferences may be noted : — 



(1) The colour is almost brick-red. 



(2) The verrucae are slightly smaller and are more adpressed to the 



coenenchyma. (Both these differences are probably due to greater 

 retraction and to the fact that the colony itself is smaller.)

In the Littoral Collection of the Indian Museum there are four filiform 

 colonies which have the characteristic spiculation of S. fwrcata, to which 

 species we have therefore assigned them. They difler considerably in
