colour but are partly overgrown by a white spongy growth. The verruca; are 

 large and cylindrical and are disposed in irregular spirals ; the anthocodini are 

 white and retractile. 



Telesto rubra, Hickson. 



This species is represented by a number of fragments of a bright coral-red 

 colour, one of which has a basal attachment on a piece of rock overgrown by 

 Polyzoa. The largest is 70 mm. in height. The diameter of the main stem is 

 3 mm., that of the branches 1 mm. 



The polyps are borne in irregular spiral s, those on one side being about 

 3 mm. apart. The verrucii2 vary in height from 1 to 25 mm. The anthocodii^ 

 are white and are completely retractile ; they contain numerous small colourless 

 spicules. When contracted they display an octo-radiate stellate structure. 

 The axial portion, though apparently composite, does not disintegrate on 

 boiling. At the ends of the verructii, when the polyps are partially retracted, 

 individual spicules occur in eight groups meeting in the centre and forming 

 a cone ; these bands are the continuation of eight ridges on the hollow tubes. 

 The spicules agree with those of the type specimen.

Previously recorded from Maldive Islands, 23-25 fathoms ; and Trincomalee. 



Telesto trichoste mma, Dana. 



In the Wood-Mason Collection there is a small terminal twig of a Telesto 

 colony which we refer to the species tricJiostenwia. It is 70 mm. in length and 

 is of a cream-white colour ; it agrees in great detail {ej/., as to form and 

 dimensions of spicules) with the description given by Wright and Studer in 

 the " ' Challenger ' Report " on Aleyonaria. See also Thomson and Henderson, 

 Alcyonaria, in "Ceylon Pearl Oyster Report".

A beautiful colony of a creamy-white colour, flattened in one plane with 

 bilateral symmetry, so that the pro-, meta- and para-rachidial surfaces are easily 

 distinguished. The following are some of the measurements in millimetres : —
