P. 5" longa, plumd oblongo-ovali, stipite terete ; rachidis dor so dilatato 

 ad latera granulato, et media sulcato ; pinnularum margine caliculis 

 dentato-setaceis pectinato. 



Five inches in length, base terete; back of the rachis dilated, with a 

 sulcus along the middle, and the sides granulous ; margin of the 

 pinnules pectinated with dentato-setaceous calicles. 



Mediterranean Sea. 



This species is rather larger than the phosphorea. The back of the 

 rachis is broader, and its middle smooth or nearly so. The colour, 

 according to Lamarck, is sometimes whitish, and on this account he 

 proposed to substitute the specific name granulosa in place of rubra. 

 The basal portion of the zoophyte is nearly half the length of the 

 whole, and the length of the plumose portion about two and a half 

 times its breadth. The axis is terete and whitish. It has been sug- 

 gested that this species is only a variety of the phosphorea.
