ALC YON ARIA. 317 



In another specimen the branching was not at all in one plane ; in another there 

 was abundant anastomosis. 



Locality : -West of Periya Paar. 



Verrucella flexuosa, var. gallensis, n. Plate III., fig. 9 ; Plate V., fig. 11. 



This variety is represented by a slightly damaged colony and several large and small 

 pieces of colonies. The complete specimen has a height of 47 millims. and a maximum 

 diameter of 53 millims. The basal attachment consists of a flat plate-like spreading 

 portion from which the main stem rises. The stem is rigid and brittle, very 

 calcareous in nature, and rises to a height of 13 millims. before it gives off the first 

 branch. The branches are given off at right angles and they in their turn give off 

 branches in a similar manner. The tips of the twigs and branches are occupied by 

 two divergent polyps which gives them a slightly flattened appearance. The branches 

 are given off in an irregularly alternate manner from the main stem and from the 

 larger branches. The branching is confined to one plane. The colour varied from 

 rose-red to vermilion. 



The verrucse are blunt and conical shaped, measuring 0'7 millim. in height and 

 having a basal diameter of 0'8 millim. to 1 millim. They are confined to the lateral 

 surfaces of the stem and branches, but are directed a little more to one surface than 

 to the other. They are arranged in such a way that the verrucas on the one lateral 

 face alternate with the verruca on the other face. 



The general coenenchyma is very thin and is composed of spindles, double clubs and 

 double spindles. 



This variety is represented by a large number of fragments, mostly small. The 

 branching in some of the fragments is confined to one plane, but in others the 

 branches are given off on all sides. The axis is cylindrical, white in colour and very 

 calcareous. In the several fragments it shows considerable differences in diameter. 



The verrucse are small, conical shaped, with a wide base. They measure 0'5 millim. 

 in height and have a basal diameter of fully 1 millim. They occur all round the main 

 stem or branch and also on the other branches, but on portions of the older branches 

 and on the younger branches they are more or less confined to the lateral surfaces. 



The general ccenenchyma is thin and is chiefly composed of spindles and double 

 clubs. They are covered by whorls of rough warts. In the double clubs there is a 

 very short bare shaft in the middle. Their measurements, length by breadth in 

 millimetres, are as follows : 



Spindles, O'lO X 0'04 ; 0'08 X 0'03 ; O'lO X 0'03 ; 0'12 X 0'03. 



Double clubs, 0'08 X O'OG ; O'lO X 0"04 ; 0'07 X 0'04 ; 0'085 X 0'04. 



Localities : Deep water off Galle ; Gulf of Manaar. 



Verrucella sp. (?). 



A small fragment, from which several branches are given off in one plane, measures 

 63 millims. in height.
