primaries themselves, from which they diverge at such an angle that they 

 mutually meet and coalesce at a point about midway between the origin 

 of the secondary of that system and the axis 

 of the calice, but at a level much lower than 

 the margin ; the two united plates thence pro- 

 ceed in the intermediate line to join the 

 columella. In many examples, however, this 

 continuation of the united quinarie3 is obsolete 

 in each .alternate system. Tho quinaries that 

 are contiguous to the secondaries (the 7th 

 order) are also much developed, but not so 

 as to equal 'the secondaries, with which they 

 often cohere. 



ANIMAL. 



Form. 



Column. Cylindrical, extensile, smooth, or somewhat invected. 



Dish Protrusile, in the form of a high truncate cone, on the summit 

 of which is the mouth, without any thickened or furrowed lip. No traco

Colour. 



Column and Disk. Yivid scarlet in adults, orange in youug individuals, 

 opaque. 



Tentacles. Gamboge yellow : the hue residing only in the warts. 



Size. 



Diameter of corallum one-fourth of an inch at margin, and occasionally

 in full expansion may reach one-third of an inch in diameter, and one-half 

 in height. 



Locality. 

 The coast of North Devon : on rocks at extreme low water. 



This showy little Coral, interesting not merely for its 

 "beauty while alive, but for its peculiar structure when dead, 

 was discovered by myself in 1852. I had been spending a
