Alcyonium klunzingeri, n. sp. 



Two exqui.site and distinctive colonies, one of a cream colour, the other 

 pink with just a hint of purple. Both are of an encrusting nature and have been 



attached to rocks, so that the general basal 

 contour is irregular. The basal portion of the 

 larger is 65 mm. long and 60 mm. in breadth ; 

 similar measurements in the other are 65 mm. 

 and 50 nun. In neither does the height exceed 

 25 mm. 



From the flat expanded base numerous 

 small mamilliform lobes arise. The largest of 

 these are about 12 mm. in height and 8 mm. in 

 diameter. They terminate in blunt cones or 

 domes, Init otherwise are cylindrical. Some of 

 the lobes are slightly flattened, and several bifur- 

 cate or even give rise to three smaller lobes. The 

 whole colony may be said to be more hard than 

 fleshy ; the canal walls are densely packed with 

 small spicules. The coenenchymal canals are cylindrical and very distinct;
