0-38 mm. by O'l mm. to 14 mm. (3) Tri- and quadri-radiate forms 053 mm. 

 X 0'07 mm. to 0"14 mm. Verriicte spicules with expanded ramifying basal 

 portion — q^ine smooth, length 0'35 to 0'65 mm., breadth 0'177 to 0"46 mm., spine 

 0'25 to 0'37 mm. by 0-053 to 0087 mm. Anthocodiae : curved fusiform spicules 

 with smooth ends. 



Localities: Port Curtis, Queensland, 5-11 fathoms; Port Molle, Queens- 

 land, 12-20 fathoms ; Warrior Reef, Torres Straits. 



Specimens from the Gulf of Manaar reveal the following differences : — 



(1) Verrucpe are twice as long as in the type specimen. 



(2) The verrucfe spicules with ramifying basal portion vary from 07 mm. 

 to on mm. in length.

Branched in one plane, anastomosing. Camenchyma thick, ends of branches 

 club-like. Polyps crowded all round the periphery at right angles to the stem. 

 Calyces cylindrical truncated, opercular region does not project. Polyps 0'8 

 to 1 mm. in diameter. The spicules of the crenenchyma are either (1) simple 

 spindles straight or curved with tubercles which are often branched, or (2) 

 spindles with lateral branched prominences. The spicules of the calyx are 

 pointed spindles with expanded basal portions which give off several (2-6) 

 downwardly directed lobes, provided with simple or complex spines. The 

 opercular coverings are composed of thin fusiform spicules placed on the basal 

 portion of each tentacle. Colour — dark red. 



Locality : Panay, Philippines ; 20 fathoms.

Plate III. 



Colony slightly branched ; branches of uniform thickness. Verrucre cover 

 the cortex, higher than broad, expanded " orally ". Polyps arise vertically, 

 close together ; the upper part of the verrucie is provided with numerous pro- 

 jecting spines, the upper bent over the mouth almost closing it. The tentacular 

 operculum is quite withdrawn. Axis horny, flexible, brown. The cortex is 

 thick with a coarse granular surface under the lens. The spicules are red, 

 heterogeneous spindles, clubs, stars and other irregular forms. The spindles 

 are strongly warted, straight or curved, often with longer or shorter warty 

 processes at one or both ends. Larger spindles are 065 mm. x 0'09 mm, to 015 

 mm. ; warty knobbed clubs sometimes apparently stellate at one end ; most 

 abundant are 3-5 rayed warty stars ; irregular perforated plates in calyces
