in breadth from which there arise four digitiform processes almost at right angles. 

 These average 2'5 cm. in height and 1 cm. broad, each again bearing a similar 

 ott'shoot.

The interior of the stalk is very soft and has very few spicules. The 

 partitions of the walls are thicker than usual, and there is a distinctly gelatinous 

 mesogla?a. 



The whole surface of the colony bears verruca^, '2 5 mm. high and 2 mm. 

 broad, built up of long spicules bound together. They stand appressed to the 

 main mass so that the openings are directed upwards. They are separated by 

 short intervals, being distant about 2 mm., and are so disposed that the top of 

 one is on the same level as the base of the next above it, alternating slightly but 

 not regularly. 



The anthocodite are wholly retractile within these verrucpe, and show a 

 distinct " crown and points ". The " points " are composed of five to eight 

 spindles arranged somewhat irregularly. The " crown " contains about five 

 rows of curved interlocking spindles all red in colour. 



The spicules of the coenenchyma are lai-ge, red, transparent, irregularly 

 tvvisted spindles and have the following measurements in millimetres : 1"5 x 05 ; 

 1-8 X 0-2; 2x0-3. 



Those of the anthocodia; are club-shaped and curved spindles, red and 

 transparent, with the following measurements" in millimeti'es : 0*8 x 0'06 ; 

 0-6 X 005 ; 0-5 x 004. 



This species bears a strong resemblance to Nidalia macrospina, Kiikenthal. 



Locality : Off Puri Orissa Coast, 10 fathoms.
