 ty. The flat Side is that diredlly forwards, 

 whofe Appearance makes it probable it may 

 be furnifhed from End to End with Rows 

 of Httle moveable Pipes or Suckers, as the 

 Arms of a Star-Fiih are : but this Confor-

 either in part, or in the whole. On the con- 

 vex-fide, and along the Edges, are numberlefs 

 Papilla or Protuberances, from each whereof

 Veflel like a Spine paffing through them from 

 the Polype\ Body to the Extremity of the 

 Arm. Thefe Articulations, w^hen the Arm

 then examining them by the Microfcope: for when the Crea- 

 ture was a]ive, and the Arms moving in the Water, I could 

 not be certain of them.
