"Colour — Stem and main branches yellowish-white; twigs becoming 

 gradually orange ; polyps white. 



" //'//'. : Two specimens from Bay of Bengal. 



" Spongodes elegans, Harrison. 



" IMain stem divides into two branches, each of which divides again into 

 two, and these further subdivide into numerous twigs ; two lower branches 

 form a flattened collar nearly encircling the stem. Polyps, borne on stalks 

 1 mm. long, in clusters of four to eight ; one large spicule projects about '2 mm. 

 below each polyp. Anthocodia with eight double rows of four to six spicules 

 arranged ' en chevron,' outermost lai'ger and projecting beyond bases of ten- 

 tacles. Tentacles with double row of colourless spicules. 



"Colour — Sterile stem a light brick-red; main branches white, shading 

 gradually from pink to red twigs ; polyps red with white tentacles. 



" HafK : Bay of Bengal. 



"Spongodes biformata, Harrison. 



" Two lower branches flattened, forming two nearly complete semicircles 

 round stem ; above these two lateral branches, and above these again the main 

 stem divides into two branches which further subdivide and bear polyps in 

 biuidles of four to eight on stalks of 1-2 mm. Polyp-heads protected by bundle 

 of three to five .spicules, two or three of which project slightly. On the lower 

 flattened branches polyps alternately borne on stalks or sessile on the edge of 

 the flattened branch. Branches very distinctly in one plane. Spicules of 

 anthocodia 'en chevron' in eight double rows of four to six spicules each, all 

 the same size and not projecting beyond bases of tentacles. 



" Colour — Base nearly white ; all other spicules of stem, branches, antho- 

 codia, and tentacles yellow. 



"Hah..- Bay of Bengal." 



" B. Form belonging to the Divaricate rigida group of Kiikenthal. 



"Spongodes rubescens, Harrison. 



" Whole colony very firm and rigid ; main stem divided into numerous short 

 branches which subdivide into smaller branches and twigs bearing polyjjs in 

 groups of two to eight at about right angles to branch. Lower branches 

 flattened, one partly encircling the stem, others forming flattened plates with 

 polyps all round the edges. One spicule projects about 1 mm. beyond each 

 polyp. Spicules of anthocodia more or less in eight double rows, but chevron
