GENERAL DESCRIPTION. 



Form. 



Base. Adherent to rocks; considerably exceeding the column; generally 

 lengthened-ovate in outline. 



Column. Low and broad, scarcely rising to a pillar-form. Surface 

 covered with warts about equal in size, arranged in forty-eight longitu- 

 dinal rows, of which the alternate rows are traceable from the margin only 

 about half-way down the column ; the warts are contiguous vertically, but 

 the rows are separated laterally, by interspaces of equal width, of corru- 

 gated skin. The primary rows consist of about twenty-four warts, 

 becoming indistinct towards the base; the uppermost individuals of all 

 the rows crowning the margin as blunt teeth. 



Dish. Flat ; the outline nearly circular, often much overlapping the 

 column. Radii distinct ; gonidial radii broad and strongly marked. 



Tentacles. Nearly marginal, set in five rows ; 6, 6, 12, 24, 24 = 72 : the 

 first three rows nearly equidistant from the centre. They are longer and 

 more slender than in gemmacea, conical, obtuse ; decreasing in size from 

 the first row outwards ; and are usually carried horizontally spread, with 

 a very constant tendency to curl upward at the tips. 



Mouth. Raised on a cone ; often gaping ; throat membranous, protru- 

 sile : gonidial tubercles usually prominent, often inflated. 



Colour. 

 Base. Red, sometimes rich crimson.
