Celliferous Corallines. jp 



placed alternately, and clofely united at the lower Part of 

 the Sides : Their Entrances are very wide ; and the upper 

 Part of them, which projeds, is full of fniall Hairs like Eye- 

 laflies. Their Bafes are narrow, and feem to be jointed ; 

 and if we look attentively in the Microfcope, we may difco- 

 ver a fmall white Hair, which feems to pafs through the 

 Middle of each Branch at the joining of the Cells. This Co- 

 ralline bears teftaceous Bodies on the Front of the Cells, 

 fomewhat refembling the upper Part of an Helmet ; and at 

 the Sides of fome of tlie Cells, little Figures like Birds Heads, 

 not unhke thofe of the fecond celliferous Coralline. 



At Fig. Z), we have the magnified Figure of this Coral- 

 line : And at d, N^ 5. the natural Size of it. Of all this Clafs 

 of Qorallines, this is one of the moft delicate and tender.

 Tufted Ivory Coralline. 



This Coralline, carefully examined in the Microfcope, ap- 

 pears to arife from minute compreffed Globules, which have 

 been depofited on a Fucus : In the Centre of each of thefe, 

 we may obferve a fmall Hole, from whence proceed very 

 (lender jointed Tubes, which pafs into Branches confifting ot 

 double Rows of tubular Cells placed almoft oppofite, and 

 united at the Sides ; but the Tops ftanding out a little : From 

 the Side of thefe Branches proceed here and there fmall hol- 

 low Veficles, which are very brittle, and full of fmall Specks. 

 Clofe to one Side of the Veficles, we have obferved a fmall 

 Tube, which, no doubt, is the Entrance into them. This 

 Species comes very near to the Clafs of veficular Corallines; 

 for in fome Specimens of this Species at the Sea-fide, we have
