A fingle fpecimen only of this curious and certainly nondefcript 

 j^lga was received by Mr. Wigg from the Mediterranean, along 

 with fome other marine plants; but of the particular place of 

 growth he could obtain no certain information. It had fo much 

 the habit and appearance of Fucus loreus, that it was at firfl: looked 

 upon as a fpecimen of that plant, overgrown and fpoiled by Flujira 

 ■p'tlofa. On putting it into water, it loft its comprefled, and affumed 

 a round form; and it was then obferved that the whole farface was 

 compofed of minute granulations, which had, whilft it was dry, given 

 it that roughncfs of appearance, but which in reality more refem- 

 bled a wooUinefs or hairinefs than the FluJlra pilofa. From a care- 

 ful examination of it in this fituation, the above fpecific chara£ler 

 and defcription were drawn up ; and from the very fingular circum- 

 flance of the exterior granulations appearing entirely naked, and 

 not being covered by any outer coat or epidermis whatever, the 

 trivial rtame of ^fcorZ/Vd'/^ was given to it. The whole length of 

 this particular fpecimen is fix feet fix inches ; the breadth of the 

 laro-eft branch, where uncomprefied, four lines. There is no ap- 

 pearance of any root, but the bafe of the frond is expanded, and by 

 this it has evidently adhered to its place of growth. Near the bafe 

 it is branched into three or four or more parts ; one of thefe is 

 very Ihort; two others are dichotoraoufly divided at about fix 

 inches from their origin, after which they continue fimple to their 

 terminations. The longeft branch, or, as it may be confidered,
