42. Gorgon I A pectinata. Branching ; principal 

 branches dispersed, and pectinated on the inside ; 

 smaller branches proceeding from only one side, sim- 

 ple, upright, parallel, long, and pointed ; polypi tu- 

 berculous, and scattered ; axe whitish ; rind red, and

Indian Ocean. 



Noia. This species has been regarded, and with rea- 

 son, as one of the most beautiful and remarkable of 

 the Gorgonian Polypidoms. 



I am inclined to believe it is to be met with in the 

 Mediterranean, and also in the Red sea.

 only on one part, always curved in the upper part 

 and near the stem.

 branches.

 nated ; pinules alternate, stiff, either simple or slightly 

 branching ; papillous polypi, verticillated, ascending,
