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

 the genus formerly known as Ctenocella ; so that the diagnosis of that genus 

 in the early records summarizes the specific characters. 



Valenciennes, in establishing the genus (C'omi)tes Eendus, t. xli., p. 14), 

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

 baguettes droites et pectin^es d'uu seul cote de la tige prineipale." 



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



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

 cote " ; and also : " Polypieroide dont la tige etles branches sont cylindriques 

 et ressemblent beaucoup aux Juucelles. Scl^renchyme sub-verruqueux. 

 Couleur jaune-rougeatre. 



" Localitd. — Mers de I'lnde." 



Wright and Studer (1., p. Ixvi) gave the following diagnosis : — 



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

 arise in an ascending order from the upper surface of the stem. Tiie verrucae 

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

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

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

 provided with two, often three, whorls of tubercles. The inner whorl so 

 approach in the middle of the spicules that the median naked zone which us 

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



With regard to the "Alert" specimens, PJdley 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. The verrucae are but slightly 

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