This species, as we have already pointed out, is the sole representative of 

 the genus formerly known as CtenoceUa ; .so that the diagnosis of that genus 

 in the early records summarizes the specific characters. 



Valenciennes, in establishing the genus (Comptes Eendus, t. xli., p. 14), 

 gave the following generic diagnosis : — " Le sclerobase s'allongeant en 

 baguettes droites et pectinees d'un .seul cote de la tige priiicipale." 



Milne-Edwards and Haime in 1857 refer to the genus as follows : — 



" Polypi^roide s'allongeant en baguettes droites et pectinees d'un seul 

 c6t^ " ; and also : " Polypieroide dont la tige et les branches sent cylindriques 

 et ressemblent beaucoup aux Juncelles. Sclerenchyme sub-verruqucux. 

 Couleur jaune-rougeatre. 



" Zoca^i^^.— Mers de I'Inde." 



Wright and Studer (1., p. Ixvi) gave tlu; fnllipwing diagnosis: — 



" The colony is branched in one plane ; and so tliat all the simple twigs 

 arise in an ascending order from the upjicr surface of the stem. The verrucac 

 are short on two sides of the twigs. There ar» distinct median furrows. The 

 spicules are warty double-clubs ; those of the polyp-calyces are, according to 

 Ridley, somewhat different from those of the coenenchyma, being longer and 

 pi'ovided with two, often three, whorls of tubercles. Tlio inner whorl so 

 approach in the middle of the spicules that the median naked zone which it. 

 characteristic of the spicules of the coenenchyma is here absent." 



With regard to the "Alert" specimens, Ridley says: — "The front and 

 back of the two main (outer) branches are bare of polyps for from one-third 

 to half their length from their origin. Tlie verrucae arc but slightly 

 prominent on the outer branches. The colour is pale salmon." 



Localities, — Warrior Reefs, Torres Straits, 12 fathoms.
