PLATE CLXVI. 



covered here, after passing through the collections of the late Dutchess 

 of Portland, and Dr. Fordyce, is at present in our possession. 



There are several interesting remarks upon this singular genus in 

 a paper written by the late Mr. John Ellis ; which is inserted in the 

 transactions of the Royal Society, for the year 1758 : the letter is 

 addressed to Mr. Isaac Romilly, a member of the society, and con- 

 tains in particular, the following observation upon Lepas Seal- 

 ■pellum. " Fig. 2," he says, referring to his illustrative plate, " is 

 the next animal of this class : this is not yet described. I found several 

 of them sticking to the vvarted Norway Sea Fan, which Dr. Pantop- 

 pidan, the Bishop of North Bergen, sent you : from its appearance, 

 I have called it the Norway Sea Fan Penknife". The stem of this is 

 covered with little testaceous scales. The Upper part of the animal 

 is enclosed in thirteen distinct shells, six on each side, besides the 

 hinge-shell, which is common to both sides : these are connected 

 together by a membrane that lines the whole inside. 



Gmelin speaks of it as a native of the Norway seas.
