Family 

 Callistephanus koreni, Wright and Sluder. 



This species is represented by a portion of a colony, of a beautiful coral red 

 colour, 83 mm. in height. 



The main stem, or branch, is about 2'5 mm. in diameter, and -iff eight 



branches (6-28 mm. in length), two of which again branch. All the branches 

 arise nearly at right angles, and lie for the most part in one plane. Two of the 

 smaller branches and one of the twigs arise almost at right angles to the general 

 plane of branching. The branching is more profuse than Wright and Stutler 

 supposed. 



The verrucse are arranged alternately on all sides of the main stem, but in tlir 

 smaller branches they are more or less confined to the lateral faces. Wright and 

 Studer describe them as altogether lateral. The termination of a branch or twig- 

 is occupied by two diverging verrucse. The distance between two verrucse on the 

 same side varies from 3-4 mm. in the main stem, but is usually less in the 

 smaller branches and twigs. The verrucse have a maximum height and a 

 maximum basal width of 2 mm. The polyps are capable of complete retraction ; 

 the tips of the tentacles are visible in a few. 



The coenenchyma is rough and of moderate thickness. The spicules com- 

 posing it are warty spindles, club-like spicules, and a few irregularly quadri- 

 radiate forms. They vary in size as follows : 



1. Warty spindles, 0'15-0'35 mm. in length and from '02-0 '05 mm. in 



breadth. 



2. Club-like spicules, 0'09-0'12 mm. in length, and from 0'04-0'07 mm. 



in breadth. 



3. Quadriradiate forms, '13-0 '16 mm. from tip to tip in one direction, 



0' 1-0 '12 mm. in the other. 

 Locality : Andaman Sea ; 238-290 fathoms. 



Previously recorded from "Challenger" Station 344 off the Island of Ascen- 

 sion ; 420 fathoms.
